Typhoon Goni

Typhoon Goni, known in the Philippines as Super Typhoon Rolly, was an extremely powerful tropical cyclone that made landfall as a Category 5–equivalent super typhoon on Catanduanes in the Philippines and in Vietnam as a tropical storm, and became the strongest landfalling tropical cyclone on record by 1-minute winds, eclipsing the previous record held by Haiyan and Meranti. The nineteenth named storm, ninth typhoon, and second super typhoon of the 2020 Pacific typhoon season, Goni originated as a tropical depression south of Guam on October 26. It was then named as Tropical Storm Goni on October 27. On the next day, Goni explosively intensified over the Philippine Sea, becoming a Category 5–equivalent super typhoon on October 30. Goni maintained Category 5 strength for over a day, before making landfall on Catanduanes at peak intensity, with 10-minute sustained winds of 220 km/h (140 mph), [1] and 1-minute sustained winds of 315 km/h (195 mph), with a minimum central pressure of 905 hPa (mbar; 26.72 inHg). It was the second-most intense tropical cyclone observed worldwide in 2020, after Cyclone Yasa, and one of the most intense tropical cyclones on record. [2]

Following its first landfall, Goni rapidly weakened while it moved over the Philippines. The storm brought severe flash flooding to Legazpi, as well as lahar flow from the nearby Mayon Volcano. There were widespread power outages as well as damaged power and transmission lines in Bicol. Crops were also heavily damaged. Over 390,000 out of 1 million evacuated individuals have been displaced in the region. Due to the extreme wind speed of the typhoon, two evacuation shelters had their roofing lost. Debris and lahars had also blocked various roads, as well as rendering the Basud Bridge impassible. In Vietnam, where Goni made landfall as a tropical depression, there was flooding in numerous areas, as well as eroded and damaged roads. This exacerbated the 2020 Central Vietnam floods, causing an estiamted ₫543 billion (US$23.5 million). In all, the typhoon killed at least 32 people and caused at least ₱20 billion (US$415 million) worth of damage. [3] The COVID-19 pandemic was also a concern for people in evacuation centers. [4]

After Goni moved into the West Philippine Sea, it subsequently weakened into a tropical storm. It started to move generally westward towards Vietnam. It eventually reached the country late on November 5 as a tropical depression, bringing heavy rain and gusty winds. International relief from several countries as well as the United Nations followed soon after the typhoon moved away from the Philippines. [5] The relief included donations totaling up to $11.48 million and protection from the pandemic, among other items. Due to the damages caused by the typhoon, the name Rolly will be retired and will be replaced with a new name for a future typhoon season.

Typhoon Hagibis
Typhoon Hagibis at peak intensity on October 7

Typhoon Hagibis, known in Japan as Reiwa 1 East Japan Typhoon (令和元年東日本台風, Reiwa Gannen Higashi-Nihon Taifū), was an extremely violent and large tropical cyclone that caused widespread destruction across its path. The thirty-eighth depression, ninth typhoon, and third super typhoon of the 2019 Pacific typhoon season, it was the strongest typhoon in decades to strike mainland Japan, and one of the largest typhoons ever recorded, with a peak gale-force diameter of 825 nautical miles (950 mi; 1529 km). Hagibis was also the deadliest typhoon to strike Japan since Typhoon Tip in 1979. Its death toll is marginally higher than that of Typhoon Bess in 1982 and Typhoon Tokage in 2004.

Hagibis developed from a tropical disturbance located a couple hundred miles north of the Marshall Islands on October 2, 2019. The Joint Typhoon Warning Center issued a red tropical cyclone formation alert - noting that the disturbance could undergo rapid intensification upon being identified as a tropical depression. On the next day, October 3, both the Japan Meteorological Agency and the Joint Typhoon Warning Center began issuing advisories on Tropical Depression 20W. The depression stayed at the same intensity as it travelled west toward the Mariana Islands on October 4, but on October 5, 20W began undergoing rapid intensification and early that day, the system was issued with the name "Hagibis" by the JMA, which means speed in Filipino. Sea surface temperatures and wind shear became extremely favourable for tropical cyclogenesis and Hagibis started extremely rapid intensification on October 6, and became a Category 5 super typhoon in under 12 hours - the second of the 2019 Pacific typhoon season. Edging closer to the uninhabited areas of the Mariana Islands, Hagibis displayed excellent convection as well as a well-defined circulation. The system developed a pinhole eye and made landfall on the Northern Mariana Islands at peak intensity, with 10-minute sustained winds of 195 km/h (120 mph) and a central pressure of 915 hPa (27.02 inHg).

Land interaction did not affect Hagibis much, but as the system continued to move westward, it underwent an eyewall replacement cycle, which is usual for all tropical cyclones of a similar intensity. The inner eyewall was robbed of its needed moisture and Hagibis began to weaken, but it formed a large and cloud-filled eye, which then became clear, and Hagibis reached its second peak. Travelling toward Japan, Hagibis encountered high vertical wind shear and its inner eyewall began to degrade, and the outer eyewalls rapidly eroded as its center began to be exposed. On October 12, Hagibis made landfall on Japan at 19:00 p.m JST (10:00 UTC) on the Izu Peninsula near Shizuoka. Then, an hour later at 20:00 p.m. JST, (11:00 UTC), Hagibis made its second landfall on Japan in the Greater Tokyo Area. Wind shear was now at 60 knots (69 mph; 111 km/h), and Hagibis' structure became torn apart as it sped at 34 knots (39 mph; 63 km/h) north-northeast toward more hostile conditions. On October 13, Hagibis became an extratropical low and the JMA and JTWC issued their final advisories on the system. However, the extratropical remnant of Hagibis persistent for more than a week, before dissipating on October 22. Hagibis caused catastrophic destruction across much of eastern Japan. Hagibis spawned a large tornado on October 12, which struck the Ichihara area of Chiba Prefecture during the onset of Hagibis,; the tornado, along with a 5.7 magnitude earthquake off the coast, caused additional damage those areas that were damaged by Hagibis. Hagibis caused $15 billion (2019 USD), making it the costliest typhoon on record.

Cyclone Winston
Winston at record peak intensity near Fiji on 20 February

Severe Tropical Cyclone Winston was the most intense tropical cyclone in the Southern Hemisphere on record, as well as the strongest to make landfall in the Southern Hemisphere, with the possible exception of 1899's Cyclone Mahina in both regards. Winston is also the costliest tropical cyclone on record in the South Pacific basin. The system was first noted as a tropical disturbance on 7 February 2016, when it was located to the northwest of Port Vila, Vanuatu. Over the next few days, the system gradually developed as it moved southeast, acquiring gale-force winds by 11 February. The following day, it underwent rapid intensification and attained ten-minute maximum sustained winds of 175 km/h (110 mph). Less favourable environmental conditions prompted weakening thereafter. After turning northeast on 14 February, Winston stalled to the north of Tonga on 17 February. Due to a change in higher level steering, the storm drifted back to the west. In the process, Winston again rapidly intensified, reaching Category 5 intensity on both the Australian tropical cyclone scale and the Saffir–Simpson hurricane wind scale on 19 February. The storm passed directly over Vanua Balavu, where a national record wind gust of 306 km/h (190 mph) was observed.

The cyclone reached its peak intensity on 20 February, with ten-minute sustained winds of 280 km/h (175 mph) and a pressure of 884 hPa (mbar; 26.10 inHg), shortly before making landfall on Viti Levu, Fiji. Thereafter, the storm slowly weakened within a less favourable environment; the system turned southeast during this time, though remained well away from Fiji. It later degenerated into a remnant low, with some subtropical characteristics, on 24 February as it turned to the west and later northwest. The system persisted for more than a week over the Coral Sea before ultimately moving over Queensland, Australia and dissipating on 3 March, 26 days after being classified a tropical disturbance.

In advance of the storm's arrival in Fiji, numerous shelters were opened, and a nationwide curfew was instituted during the evening of 20 February. Striking Fiji at Category 5 intensity on 20 February, Winston inflicted extensive damage on many islands and killed 44 people. Communications were temporarily lost with at least six islands, with some remaining isolated more than two days after the storm's passage. A total of 40,000 homes were damaged or destroyed and approximately 350,000 people—roughly 40 percent of Fiji's population—were significantly impacted by the storm. Total damage from Winston amounted to FJ$2.98 billion (US$1.4 billion). The nation's government declared a state of emergency on 20 February, which remained in place for 60 days. Immediately following the cyclone, the governments of Australia and New Zealand provided logistical support and relief packages. In the following weeks, a coalition of international support, including intergovernmental agencies, brought tens of millions of dollars in aid and hundreds of tons of supplies to residents in Fiji.

Hurricane Patricia

Hurricane Patricia was an exceptionally powerful tropical cyclone that became the strongest on record worldwide in terms of wind speed and the second-most intense on record worldwide in terms of pressure, behind Typhoon Tip in 1979, with a minimum atmospheric pressure of 872 mbar (hPa; 25.75 inHg). Originating from a sprawling disturbance near the Gulf of Tehuantepec, south of Mexico, in mid-October 2015, Patricia was first classified a tropical depression on October 20. Initial development was slow, with only modest strengthening within the first day of its classification. The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. Exceptionally favorable environmental conditions fueled explosive intensification on October 22. A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. On October 23, the hurricane achieved its record peak intensity with maximum sustained winds of 215 mph (345 km/h). This made it the most intense tropical cyclone on record in the Western Hemisphere and the strongest globally in terms of one-minute maximum sustained winds.

Late on October 23, dramatic weakening ensued and Patricia made landfall near Cuixmala, Jalisco, with winds of 150 mph (240 km/h). This made it the strongest landfalling hurricane on record along the Pacific coast of Mexico. Patricia continued to weaken extremely quickly, faster than it had intensified, as it interacted with the mountainous terrain of Mexico. Within 24 hours of moving ashore, Patricia weakened into a tropical depression and dissipated soon thereafter, late on October 24.

The precursor to Patricia produced widespread flooding rains in Central America. Hundreds of thousands of people were directly affected by the storm, mostly in Guatemala. At least six fatalities were attributed to the event: four in El Salvador, one in Guatemala, and one in Nicaragua. Torrential rains extended into southeastern Mexico, with areas of Quintana Roo and Veracruz reporting accumulations in excess of 19.7 in (500 mm). Damage in Chetumal reached MX$1.4 billion (US$85.3 million).

As a tropical cyclone, Patricia's effects in Mexico were tremendous; however, the affected areas were predominantly rural, lessening the number of people directly impacted. Violent winds tore roofs from structures and stripped coastal areas of their vegetation. Preliminary assessments indicated hundreds of homes to be destroyed; seven fatalities were linked to the hurricane directly or indirectly, including one during evacuations. Total damage from Patricia was estimated to be at least $462.8 million (2015 USD); the damage in Mexico alone was estimated to be in excess of MX$5.4 billion (US$325 million), with agriculture and infrastructure comprising the majority of losses. Flooding partially associated with remnant moisture from Patricia inflicted US$52.5 million in damage across Southern Texas.

Typhoon Haiyan
Typhoon Haiyan at its near-record peak intensity while approaching the Philippines on November 7

Typhoon Haiyan, known in the Philippines as Super Typhoon Yolanda, was one of the most powerful tropical cyclones ever recorded. On making landfall, Haiyan devastated portions of Southeast Asia, particularly the Philippines. It is one of the deadliest Philippine typhoons on record, killing at least 6,300 people in that country alone. In terms of JTWC-estimated 1-minute sustained winds, Haiyan is tied with Meranti in 2016 for being the second strongest landfalling tropical cyclone on record. In January 2014, bodies were still being found.

The thirtieth named storm, thirteenth typhoon, and fifth super typhoon of the 2013 Pacific typhoon season, Haiyan originated from an area of low pressure several hundred kilometers east-southeast of Pohnpei in the Federated States of Micronesia on November 2, 2013. Tracking generally westward, environmental conditions favored tropical cyclogenesis and the system developed into a tropical depression on the following day. After becoming a tropical storm and being named Haiyan at 00:00 UTC on November 4, the system began a period of rapid intensification that brought it to typhoon intensity by 18:00 UTC on November 5. By November 6, the Joint Typhoon Warning Center (JTWC) assessed the system as a Category 5-equivalent super typhoon on the Saffir–Simpson hurricane wind scale (SSHWS); the storm passed over the island of Kayangel in Palau shortly after attaining this strength.

Thereafter, Haiyan continued to intensify; at 12:00 UTC on November 7, the Japan Meteorological Agency (JMA) upgraded the storm's maximum ten-minute sustained winds to 230 km/h (145 mph), the highest in relation to the storm. The Hong Kong Observatory put the storm's maximum ten-minute sustained winds at 285 km/h (180 mph) prior to landfall in the central Philippines, while the China Meteorological Administration estimated the maximum two-minute sustained winds at the time to be around 78 m/s (280 km/h or 175 mph). At the same time, the JTWC estimated the system's one-minute sustained winds at 315 km/h (195 mph), unofficially making Haiyan the strongest tropical cyclone ever observed based on wind speed, a record which would later be surpassed by Hurricane Patricia in 2015 at 345 km/h (215 mph). Haiyan is also tied with Meranti in 2016 and Goni in 2020 as the most intense tropical cyclone in the Eastern Hemisphere by 1-minute sustained winds; several others have recorded lower central pressure readings. At 20:40 UTC on November 7, the eye of the typhoon made its first landfall in the Philippines at Guiuan, Eastern Samar at peak strength. Gradually weakening, the storm made five additional landfalls in the country before emerging over the South China Sea. Turning northwestward, the typhoon eventually struck northern Vietnam as a severe tropical storm on November 10. Haiyan was last noted as a tropical depression by the JMA on the following day.

The typhoon caused catastrophic destruction in the Visayas, particularly on Samar and Leyte. According to UN officials, about 11 million people were affected and many were left homeless. People are still missing because of this powerful storm.

Hurricane Eta

Hurricane Eta was a devastating Category 4 hurricane that wreaked havoc across parts of Central America in early November 2020. The record-tying twenty-eighth named storm, twelfth hurricane and fifth major hurricane of the extremely active 2020 Atlantic hurricane season, Eta originated from a vigorous tropical wave in the eastern Caribbean Sea on October 31. The system rapidly organized as it progressed west, with the cyclone ultimately becoming a Category 4 hurricane on November 3. With a peak intensity of 150 mph (240 km/h) and 923 mbar ( hPa; 27.26 inHg), it was the third most intense November Atlantic hurricane on record, behind the 1932 Cuba hurricane, and Hurricane Iota just two weeks later. Some weakening took place as the system made landfall near Puerto Cabezas, Nicaragua, late that same day. Eta rapidly weakened to a tropical depression as it meandered across Central America for two days before moving north over water. It later reorganized over the Caribbean as it accelerated toward Cuba on November 7. Over the next five days, the system moved erratically, moving through the Florida Keys and stalling in the southern Gulf of Mexico, its intensity fluctuating along the way. After briefly regaining hurricane strength it weakened once more and accelerated across the Southeastern United States on November 12. It soon became extratropical and dissipated off the Eastern United States the next day.

Hurricane and tropical storm watches and warnings were issued along the coast of Honduras and Northeastern Nicaragua as Eta approached. More than 10,000 people sought refuge at shelters in Puerto Cabezas and surrounding villages. Eta knocked down power lines and trees while damaging roofs and causing flooding in Puerto Cabezas. Overall, at least 178 fatalities across Central America have been attributed to the storm, including 74 in Honduras, 53 in Guatemala, 27 in Mexico, 19 in Panama, two each in Nicaragua and Costa Rica, and one in El Salvador. Once the system began to reorganize in the Caribbean, tropical storm watches were issued on November 5, in the Cayman Islands. More watches were issued in parts of Cuba, the northwestern Bahamas, and South Florida. Eta brought heavy rainfall and gusty winds to the Cayman Islands and Cuba, the latter of which was already dealing with overflowing rivers that prompted evacuations. Heavy rainfall and tropical-storm force winds were recorded across all of the Florida Keys, South Florida and the southern half of Central Florida, bringing widespread flooding. Eta's second approach and landfall brought storm surge and gusty winds to the west coast of Central Florida and supplemental rainfall to northern Florida. One person was killed in Florida after being electrocuted in floodwaters from Eta. Moisture from the storm also combined with a cold front further to the north bringing heavy rainfall and flash flooding to the Carolinas and Virginia, killing another five people in these states. In all, 11 deaths were attributed to the storm in the U.S. Nearly $8 billion (2020 USD) in damages were reported across all affected areas by Eta as of December 2020.

Relief efforts for those affected by the storm were extensive and widespread, involving several countries. Approximately 2.5 million were affected by the storm, including 1.7 million in Honduras. Many Emergency Response Units were to be dispatched globally to help support affected people. About 98 tons of food and water were given to Nicaragua and Honduras from Panama. People left homeless were moved to various shelters after the storm had passed. Donations worth millions of USD had been given to affected countries to help recoveries. However, just two weeks later, all efforts were hindered greatly by Hurricane Iota.

Hurricane Iota
Hurricane Iota at peak intensity approaching Nicaragua on November 16

Hurricane Iota was the latest Atlantic hurricane to attain Category 5 intensity and only the second Category 5 Atlantic hurricane to occur within the month of November on record—the other being the 1932 Cuba hurricane. Iota caused severe damage to areas of Central America already devastated by Hurricane Eta just less than two weeks prior. The 31st and final tropical cyclone, 30th named storm, 13th hurricane, and sixth major hurricane of the record-breaking 2020 Atlantic hurricane season, Iota originated as a tropical wave that moved into the Eastern Caribbean on November 10. Over the next few days, the wave began to become better organized and by November 13, it developed into a tropical depression north of Colombia. The depression strengthened into Tropical Storm Iota six hours later. The storm was initially impacted by some wind shear, but a center relocation and relaxed shear allowed Iota to quickly strengthen into a hurricane on November 15, after which it underwent explosive intensification, becoming a Category 5 hurricane the following day. This made 2020 the fifth consecutive Atlantic hurricane season since 2016 to feature at least one Category 5 hurricane. After weakening slightly, Iota made landfall in northeastern Nicaragua as a high-end Category 4 hurricane, becoming the strongest recorded hurricane to make landfall in Nicaragua in November. Iota then rapidly weakened as it moved inland, dissipating on November 18.

The precursor wave to Iota generated flash flooding in most of the Caribbean islands. Tropical cyclone watches and warnings were first issued on November 14 in parts of Colombia, Nicaragua, and Honduras, with the latter two countries still recovering from Eta just two weeks prior. Heavy rains associated with a tropical wave and Iota brought heavy rainfall to parts of Colombia, leading to flash flooding and mudslides. Extremely heavy rain fell on much of Nicaragua widening flash flooding caused by the hurricane's high storm surge. Mudslides caused extensive damage and multiple deaths. At least 61 people were killed due to Iota including at least 28 in Nicaragua and 16 in Honduras, among other countries. As many as 41 people are currently missing. A preliminary estimate for the damage in Nicaragua is at $564 million (2020 USD) in that country. Total damage estimates for the hurricane are currently at $1.4 billion (2020 USD).

Planning for relief efforts soon followed, which include placing tents, opening temporary hospitals, and delivering food and water to those in need. Numerous power outages were restored in the days following Iota's destruction. Downed trees and blocked paths have slowed down some rescue teams. Donations worth hundreds of millions of USD have been given to affected countries. An estimated total of 5.2 million people were affected by the storm, while hundreds of thousands of people have been displaced.

Hurricane Dorian
Hurricane Dorian near peak intensity over the Abaco Islands on September 1

Hurricane Dorian was an extremely powerful and devastating Category 5 Atlantic hurricane, that became the most intense tropical cyclone on record to strike the Bahamas, and is regarded as the worst natural disaster in the country's history. It was also one of the most powerful hurricanes recorded in the Atlantic Ocean in terms of 1-minute sustained winds, with these winds peaking at 185 mph (295 km/h). In addition, Dorian surpassed Hurricane Irma of 2017 to become the most powerful Atlantic hurricane on record outside of the Caribbean Sea. It was the fourth named storm, second hurricane, the first major hurricane, and the first Category 5 hurricane of the 2019 Atlantic hurricane season. Dorian struck the Abaco Islands on September 1 with maximum sustained winds of 185 mph (295 km/h), tying with the 1935 Labor Day hurricane for the highest wind speeds of an Atlantic hurricane ever recorded at landfall. Dorian went on to strike Grand Bahama at similar intensity, stalling just north of the territory with unrelenting winds for at least 24 hours. The resultant damage to these islands was catastrophic; most structures were flattened or swept to sea, and at least 70,000 people were left homeless. After it ravaged through the Bahamas, Dorian proceeded along the coasts of the Southeastern United States and Atlantic Canada, leaving behind considerable damage and economic losses in those regions.

Dorian developed from a tropical wave on August 24 over the Central Atlantic. The storm moved through the Lesser Antilles and became a hurricane north of the Greater Antilles on August 28. Dorian proceeded to undergo rapid intensification over the following days to reach its peak as a Category 5 hurricane with one-minute sustained winds of 185 mph (295 km/h) and a minimum central pressure of 910 millibars (26.87 inHg) by September 1. It made landfall in the Bahamas in Elbow Cay, just east of Abaco Island, and again on Grand Bahama several hours later, where it remained nearly stationary for the next day or so. After weakening considerably, Dorian began moving northwestward on September 3, parallel to the east coast of Florida. Dwindling in strength, the hurricane turned to the northeast the next day and made landfall on Cape Hatteras at Category 2 intensity on September 6. It transitioned into an extratropical cyclone before striking first Nova Scotia and then Newfoundland with hurricane-force winds on September 8. It finally dissipated near Greenland on September 10.

From August 26 to August 28, the storm affected several parts of the northernmost Lesser Antilles. Damaging winds primarily affected the Virgin Islands where gusts reached 111 mph (179 km/h). Extensive precautionary measures were taken to mitigate damage, especially in Puerto Rico, where one person died. Elsewhere in the Lesser Antilles, impacts from the storm were relatively minor. In preparation for the storm, the states of Florida, Georgia, South Carolina, North Carolina and Virginia all declared a state of emergency and many coastal counties from Florida to North Carolina issued mandatory evacuation orders. Damage in the Bahamas was catastrophic due to the prolonged and intense storm conditions, including heavy rainfall, high winds and storm surge, with thousands of homes destroyed and at least 77 direct deaths recorded, 74 of which occurred in the Bahamas. The true death toll is unknown with 245 people still missing as of April 2020. Dorian is the costliest disaster in Bahamian history, estimated to have left behind $3.4 billion in damage.

Hurricane Maria

Hurricane Maria was a deadly Category 5 hurricane that devastated Dominica, St Croix, and Puerto Rico in September 2017. It is regarded as the worst natural disaster in recorded history to affect those islands and was also the deadliest Atlantic hurricane since Mitch in 1998. The tenth most intense Atlantic hurricane on record and the most intense tropical cyclone worldwide in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and deadliest storm of the hyperactive 2017 Atlantic hurricane season. At its peak, the hurricane caused catastrophic destruction and numerous fatalities across the northeastern Caribbean, compounding recovery efforts in the areas of the Leeward Islands already struck by Hurricane Irma. Total losses from the hurricane are estimated at upwards of $91.61 billion (2017 USD), mostly in Puerto Rico, ranking it as the third-costliest tropical cyclone on record.

Originating from a tropical wave, Maria became a tropical storm on September 16, east of the Lesser Antilles. Highly favorable environmental conditions allowed the storm to undergo explosive intensification as it approached the island arc. The hurricane reached Category 5 strength on September 18 just before making landfall on Dominica, becoming the first Category 5 hurricane on record to strike the island. After weakening slightly due to crossing Dominica, Maria achieved its peak intensity over the eastern Caribbean with maximum sustained winds of 175 mph (280 km/h) and a pressure of 908 mbar (hPa; 26.81 inHg). On September 20, an eyewall replacement cycle took place, weakening Maria to a high-end Category 4 hurricane by the time it struck Puerto Rico. Interaction with land further weakened the hurricane, though it regained some strength as it moved northeast of the Bahamas. Moving slowly to the north, Maria gradually degraded and weakened to a tropical storm on September 28. Embedded in the westerlies, Maria accelerated toward the east and later east-northeast over the open Atlantic, becoming extratropical on September 30 and dissipating by October 2.

Maria wrought catastrophic devastation to the entirety of Dominica, which suffered an island-wide communication blackout. Much of the housing stock and infrastructure were left beyond repair, while the island's lush vegetation was practically eradicated. The islands of Guadeloupe and Martinique endured widespread flooding, damaged roofs, and uprooted trees. Puerto Rico also suffered catastrophic damage and a major humanitarian crisis; most of the island's population suffered from flooding and a lack of resources, compounded by the slow relief process. The storm caused the worst electrical blackout in US history, and in June 2018, thousands of homes and businesses were still without power. [6] Maria was the third consecutive major hurricane to threaten the Leeward Islands in two weeks, after Irma had made landfall in several of the islands two weeks prior and Hurricane Jose passed dangerously close shortly afterward, bringing tropical storm force winds to Barbuda.

On August 28, 2018 (almost a year after the hurricane), Puerto Rico revised its official tally of 64 [7] killed in the hurricane up to 2,975, making the total death toll 3,059: an estimated 2,975 were killed in Puerto Rico, [8] 65 in Dominica, 5 in the Dominican Republic, 4 in Guadeloupe, 4 in the contiguous United States, 3 in the United States Virgin Islands, and 3 in Haiti. Maria is the deadliest hurricane in Dominica since the 1834 Padre Ruíz hurricane [9] and the deadliest in Puerto Rico since the 1899 San Ciriaco hurricane. [10] The death toll in Puerto Rico was initially reported as 64 by Puerto Rican authorities but revised after several studies estimated between 1,400 and 5,740 deaths were attributable to the storm. [8] The official estimate of 2,975 is based on a study commissioned by the governor of Puerto Rico, [8] where researchers at George Washington University developed statistical models of excess mortality attributable to Maria, including both direct and indirect fatalities. [11] Researchers attribute the discrepancy with the initial death count to "lack of awareness of appropriate death certification practices after a natural disaster" among physicians reporting deaths to vital statistic agencies. [11]

Hurricane Matthew

Hurricane Matthew was the first Category 5 Atlantic hurricane since Felix in 2007. Matthew caused catastrophic damage and a humanitarian crisis in Haiti, as well as widespread devastation in the southeastern United States. The deadliest Atlantic hurricane since Hurricane Stan in 2005, Matthew was the thirteenth named storm, fifth hurricane and second major hurricane of the 2016 Atlantic hurricane season. It caused extensive damage to landmasses in the Greater Antilles, and severe damage in several islands of the Bahamas which were still recovering from Joaquin, which had pounded such areas nearly a year earlier. At one point, the hurricane even threatened to be the first storm of Category 3 or higher intensity to strike the United States since Wilma in 2005, but Matthew stayed just offshore, paralleling the Florida coastline.

Originating from a tropical wave that emerged off Africa on September 22, Matthew developed into a tropical storm just east of the Lesser Antilles on September 28. It became a hurricane north of Venezuela and Colombia on September 29, before undergoing explosive intensification, ultimately reaching Category 5 intensity on October 1 at just 13.4°N latitude – the lowest latitude ever recorded for a storm of this intensity in the Atlantic basin, breaking the record set by Hurricane Ivan in 2004. [12] Matthew weakened slightly and fluctuated in intensity while making a northward turn toward the Greater Antilles, remaining a strong Category 4 hurricane as it made its first landfall over Haiti's Tiburon Peninsula early on October 4, and then a second one in Cuba later that day. Matthew weakened somewhat but re-intensified as it tracked northwest, making landfall in the northern Bahamas. The storm then paralleled the coast of the southeastern United States over the next 36 hours, gradually weakening while remaining just offshore before making its fourth and final landfall over the Cape Romain National Wildlife Refuge near McClellanville, South Carolina as a Category 1 hurricane on the morning of October 8. Matthew re-emerged into the Atlantic shortly afterward, eventually completing its transition into an extratropical cyclone as it turned away from Cape Hatteras, North Carolina on October 9. The remnants of Matthew continued to accelerate towards Canada where it was absorbed by a cold front. [13]

Widespread effects were felt from Matthew across its destructive path, however, the most significant impacts were felt in Haiti, with US$2.8 billion in damage and 546 deaths, making Matthew the worst disaster to affect the nation since the 2010 earthquake. The combination of flooding and high winds disrupted telecommunications and destroyed extensive swaths of land; around 80% of Jérémie sustained significant damage. Four people were killed in Cuba due to a bridge collapse, and total losses in the country amounted to US$2.58 billion, most of which occurred in the Guantánamo Province. Passing through the Bahamas as a major hurricane, Matthew spread damage across several islands. Grand Bahama was hit directly, where most homes sustained damage in the townships of Eight Mile Rock and Holmes Rock. Preparations began in earnest across the southeastern United States as Matthew approached, with several states declaring states of emergencies for either entire states or coastal counties; widespread evacuations were ordered for extensive areas of the coast because of predicted high wind speeds and flooding, especially in the Jacksonville Metropolitan Area. In Florida, over 1 million lost power as the storm passed to the east, with 478,000 losing power in Georgia and South Carolina. While damage was primarily confined to the coast in Florida and Georgia, torrential rains spread inland in the Carolinas and Virginia, causing widespread flooding.

Hurricane Irma

Hurricane Irma was an extremely powerful Cape Verde hurricane that caused widespread destruction across its path in September 2017. Irma was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Maria two weeks later. At the time, it was considered as the most powerful hurricane on record in the open Atlantic region, outside of the Caribbean Sea and Gulf of Mexico until it was surpassed by Hurricane Dorian two years later. It was also the third strongest Atlantic hurricane at landfall ever recorded, just behind the 1935 Labor Day Hurricane and Hurricane Dorian. [14]

The ninth named storm, fourth hurricane, second major hurricane, [nb 1] and first Category 5 hurricane of the 2017 season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in the northeastern Caribbean and the Florida Keys. It was also the most intense hurricane to strike the continental United States since Katrina in 2005, the first major hurricane to make landfall in Florida since Wilma in the same year, and the first Category 4 hurricane to strike the state since Charley in 2004. The word Irmageddon was coined soon after the hurricane to describe the damage caused by the hurricane. [16]

Irma developed from a tropical wave near the Cape Verde Islands on August 30. Favorable conditions allowed Irma to rapidly intensify into a Category 3 hurricane on the Saffir–Simpson wind scale by late on August 31. The storm's intensity fluctuated between Categories 2 and 3 for the next several days, due to a series of eyewall replacement cycles. On September 4, Irma resumed intensifying, becoming a Category 5 hurricane by early on the next day. Early on September 6, Irma peaked with 1-minute sustained winds of 180 mph (285 km/h) and a minimum pressure of 914 hPa (27.0 inHg). Irma was the second-most intense tropical cyclone worldwide in 2017 in terms of barometric pressure, and the strongest worldwide in 2017 in terms of wind speed. Another eyewall replacement cycle caused Irma to weaken back to a Category 4 hurricane, but the storm re-attained Category 5 status before making landfall in Cuba. Although Irma briefly weakened to a Category 2 storm while making landfall on Cuba, the system re-intensified to Category 4 status as it crossed the warm waters of the Straits of Florida, before making landfall on Cudjoe Key on September 10. Irma then weakened to Category 3 status, prior to another landfall in Florida on Marco Island later that day. The system degraded into a remnant low over Alabama and ultimately dissipated on September 13 over Missouri.

The storm caused catastrophic damage in Barbuda, Saint Barthélemy, Saint Martin, Anguilla, and the Virgin Islands as a Category 5 hurricane. The hurricane caused at least 134 deaths: one in Anguilla; one in Barbados; three in Barbuda; four in the British Virgin Islands; 10 in Cuba; 11 in the French West Indies; one in Haiti; three in Puerto Rico; four on the Dutch side of Sint Maarten; 92 in the contiguous United States, and four in the U.S. Virgin Islands. Hurricane Irma was the top Google searched term in the US and globally in 2017. [17]

Hurricane Harvey

Hurricane Harvey was a devastating Category 4 hurricane that made landfall on Texas and Louisiana in August 2017, causing catastrophic flooding and many deaths. It is tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, [nb 2] inflicting $125 billion (2017 USD) in damage, primarily from catastrophic rainfall-triggered flooding in the Houston metropolitan area and Southeast Texas. [18] [19] It was the first major hurricane [nb 3] to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at the intensity of a major hurricane throughout the country. [20] In a four-day period, many areas received more than 40 inches (1,000 mm) of rain as the system slowly meandered over eastern Texas and adjacent waters, causing unprecedented flooding. With peak accumulations of 60.58 in (1,539 mm), in Nederland, Texas, Harvey was the wettest tropical cyclone on record in the United States. The resulting floods inundated hundreds of thousands of homes, which displaced more than 30,000 people and prompted more than 17,000 rescues.

The eighth named storm, third hurricane, and first major hurricane of the extremely active 2017 Atlantic hurricane season, Harvey developed from a tropical wave to the east of the Lesser Antilles, reaching tropical storm status on August 17. [21] The storm crossed through the Windward Islands on the following day, making landfall on the southern end of Barbados and a second landfall on Saint Vincent. Upon entering the Caribbean Sea, Harvey began to weaken due to moderate wind shear, and degenerated into a tropical wave north of Colombia, late on August 19. [22] The remnants were monitored for regeneration as it continued west-northwestward across the Caribbean and the Yucatán Peninsula, before redeveloping over the Bay of Campeche on August 23. [23] Harvey then began to rapidly intensify on August 24, regaining tropical storm status and becoming a hurricane later that day. [24]

While the storm moved generally northwest, Harvey's intensification phase stalled slightly overnight from August 24–25; however, Harvey soon resumed strengthening and quickly became a major hurricane and attained Category 4 intensity later that day. [25] Hours later, Harvey made landfall at San José Island, Texas, at peak intensity, followed by another landfall at Holiday Beach at Category 3 intensity. Rapid weakening then ensued, and Harvey had downgraded to a tropical storm as it stalled near the coastline, dropping torrential and unprecedented amounts of rainfall over Texas. [26] On August 28, it emerged back over the Gulf of Mexico, strengthening slightly before making a fifth and final landfall in Louisiana on August 29. [27] As Harvey drifted inland, it quickly weakened again as it became extratropical on September 1, before dissipating two days later. [28]

In addition to the huge cost and extent of the damage it caused, Harvey caused at least 107 confirmed deaths: 1 in Guyana and 106 in the United States, the first one in Rockport, Texas. [29] Due to the extensive damage, the name "Harvey" was retired in April 2018 and will not be used for another Atlantic tropical cyclone. [30] [31]

Hurricane Sandy

Hurricane Sandy (unofficially referred to as Superstorm Sandy) was the deadliest and most destructive, as well as the strongest hurricane of the 2012 Atlantic hurricane season. The storm inflicted nearly $70 billion (2012 USD) in damage and killed 233 people across eight countries from the Caribbean to Canada. The eighteenth named storm, tenth hurricane, and second major hurricane of the year, Sandy was a Category 3 storm at its peak intensity when it made landfall in Cuba. While it was a Category 2 hurricane off the coast of the Northeastern United States, the storm became the largest Atlantic hurricane on record (as measured by diameter, with tropical-storm-force winds spanning 1,150 miles (1,850 km)).

Sandy developed from a tropical wave in the western Caribbean Sea on October 22, quickly strengthened, and was upgraded to Tropical Storm Sandy six hours later. Sandy moved slowly northward toward the Greater Antilles and gradually intensified. On October 24, Sandy became a hurricane, made landfall near Kingston, Jamaica, re-emerged a few hours later into the Caribbean Sea and strengthened into a Category 2 hurricane. On October 25, Sandy hit Cuba as a Category 3 hurricane, then weakened to a Category 1 hurricane. Early on October 26, Sandy moved through the Bahamas. On October 27, Sandy briefly weakened to a tropical storm and then restrengthened to a Category 1 hurricane. Early on October 29, Sandy curved west-northwest (the "left turn" or "left hook") and then moved ashore near Brigantine, New Jersey, just to the northeast of Atlantic City, as a post-tropical cyclone with hurricane-force winds. Sandy continued drifting inland for another few days while gradually weakening, until it was absorbed by another approaching extratropical storm on November 2.

In Jamaica, winds left 70% of residents without electricity, blew roofs off buildings, killed one person, and caused about $100 million (2012 USD) in damage. Sandy's outer bands brought flooding to Haiti, killing at least 54, causing food shortages, and leaving about 200,000 homeless; the hurricane also caused two deaths in the Dominican Republic. In Puerto Rico, one man was swept away by a swollen river. In Cuba, there was extensive coastal flooding and wind damage inland, destroying some 15,000 homes, killing 11, and causing $2 billion (2012 USD) in damage. Sandy caused two deaths and an estimated $700 million (2012 USD) in damage in The Bahamas.

In the United States, Hurricane Sandy affected 24 states, including the entire eastern seaboard from Florida to Maine and west across the Appalachian Mountains to Michigan and Wisconsin, with particularly severe damage in New Jersey and New York. Its storm surge hit New York City on October 29, flooding streets, tunnels and subway lines and cutting power in and around the city. Damage in the United States amounted to $65 billion (2012 USD). In Canada, two were killed in Ontario, and the storm caused an estimated $100 million (2012 CAD) in damage throughout Ontario and Quebec.

Cyclone Amphan

Amphan near peak intensity over the Bay of Bengal on May 18

Super Cyclonic Storm Amphan ( /ˈɑːmpɑːn/) was a powerful and catastrophic tropical cyclone that caused widespread damage in Eastern India, specifically West Bengal, and in Bangladesh in May 2020. It was the strongest tropical cyclone to strike the Ganges Delta since Sidr of the 2007 season and the first super cyclonic storm to have formed in the Bay of Bengal since the 1999 Odisha cyclone. It was also the fourth super cyclone that hit West Bengal since 1582, after 1737, 1833 and 1942, as well as being one of the strongest storm to impact the area. Causing over US$13 billion of damage, Amphan is also the costliest cyclone ever recorded in the North Indian Ocean, surpassing the record held by Cyclone Nargis of 2008.

The first tropical cyclone of the 2020 North Indian Ocean cyclone season, Amphan originated from a low-pressure area persisting a couple hundred miles (300 km) east of Colombo, Sri Lanka, on 13 May 2020. Tracking northeastward, the disturbance organized over exceptionally warm sea surface temperatures; the Joint Typhoon Warning Center (JTWC) upgraded the system to a tropical depression on 15 May while the Indian Meteorological Department (IMD) followed suit the following day. On 17 May, Amphan underwent rapid intensification and became an extremely severe cyclonic storm within 12 hours.

On 18 May, at approximately 12:00 UTC, Amphan reached its peak intensity with 3-minute sustained wind speeds of 240 km/h (150 mph), 1-minute sustained wind speeds of 260 km/h (160 mph), and a minimum central barometric pressure of 920 mbar (27.17 inHg). The storm began an eyewall replacement cycle shortly after it reached its peak intensity, but the continued effects of dry air and wind shear disrupted this process and caused Amphan to gradually weaken as it paralleled the eastern coastline of India. On 20 May, between 10:00 and 11:00 UTC, the cyclone made landfall in West Bengal. At the time, the JTWC estimated Amphan's 1-minute sustained winds to be 155 km/h (100 mph). Amphan rapidly weakened once inland and dissipated shortly thereafter.

Coastal areas in West Bengal comprising East Midnapur, North 24 Parganas, South 24 Parganas, Kolkata, Hooghly and Howrah as well as Odisha were affected by the cyclone. It also caused significant destruction in Bangladesh.

Cyclone Fani

Extremely Severe Cyclonic Storm Fani ( /ˈfɒniː/) [a] was the strongest tropical cyclone to strike the Indian state of Odisha since the 1999 Odisha cyclone. The second named storm and the first severe cyclonic storm of the 2019 North Indian Ocean cyclone season, Fani originated from a tropical depression that formed west of Sumatra in the Indian Ocean on 26 April. Vertical wind shear at first hindered the storm's development, but conditions became more favorable for Fani on 30 April. Fani rapidly intensified into an extremely severe cyclonic storm and reached its peak intensity on 2 May, with 1-minute sustained winds equivalent to a Category 5 major hurricane. Fani slightly weakened before making its landfall, and its convective structure rapidly degraded thereafter, degenerating into a remnant low on 4 May, and dissipating on the next day.

Prior to Fani's landfall, authorities in India and Bangladesh moved at least a million people each from areas within Fani's projected path onto higher ground, and into cyclone shelters, which is thought to have reduced the resultant death toll and casualties. [34] Fani killed at least 89 people in eastern India and Bangladesh and caused about US$8.1 billion in damages in both India and Bangladesh, mostly in Odisha, in India. [35]
