Episode Cévenol

A first glance reveals that the regions where rainfall was more abundant are the foothills of the Cévennes mountains of south-central France, where the humid air masses from the Mediterranean were blocked by terrain. [2] The mountain range gives its name to a meteorological effect when cold air from the Atlantic coast meets warm air of southern winds from the Mediterranean and causes heavy autumnal downpours, often leading to floods. These are called épisodes cévenols. The origin of this sequence of episodes cévenols says Météo France is in the atmospheric circulation on a large scale and in particularly warm waters of the Mediterranean. We lived under a southwest "driven by a large low pressure system located over the Atlantic. This facilitates raising the France of warm air masses and very wet from the Mediterranean " says Météo France. As the Northwest part of the Mediterranean were warmer than average in September, the "engine" to manufacture cévenols episodes could run at full speed. [2] La succession de fortes pluies les 16 au 17 septembre, le 29 septembre, le 6 octobre, puis de ce vendredi 10 au lundi 13 octobre a accentué les dégâts avec la saturation des sols en eau. [2]

Peak gusts...described as equivalent to a category 3 on the Saffir-Simpson scale. [7] but hurricane uses 10 minute or sustained... Even so, the wind speeds, compared to hurricanes were relatively low. As a result, AIR Worldwide predicted that average claims size will be smaller. But because the damaging winds had such a wide reach, the total claims are expected to be significant.- http://www.carriermanagement.com/news/2015/04/07/137773.htm

The New South Wales east coast low was a severe extra-tropical cyclone that affected the state between 20–22 April

Meteorological history

Satellite Total Precipitable Water showing atmospheric moisture during storm


was an area of low pressure aloft that became trapped to the north of the active jet stream. [10] That trapping led to the slow movement of the storm. [10] This closed-off upper-level low then induced a low-pressure center just off the New South Wales coast. [10] The pressure gradient between that surface low and high pressure centered near Tasmania and the Tasman Sea lead to the intense onshore winds. [10]

strong pressure gradient between high pressure of 1037mb over Tasmania and the Australian Bight strong winds blowing onshore orographic precipitation component to rainfall as moist flows onto land uplifted as crossed over land and forced up Great Dividing Range. [10]

Impact

<---Over the last few days, strong winds and heavy rainfall from an intense low pressure system have impacted eastern portions of New South Wales (NSW), including the capital city Sydney (pop. ~ 4.8 million), the Central Coast, and the Hunter Region, which has damaged homes, caused thousands of power outages, transport disruption, and four fatalities. The BoM also reported that eastern portions of NSW were impacted by wind gusts of up to 85 mph (135 km/hr) on Monday.

New South Wales State Emergency Service responded to 20,648 calls from the event, including 170 flood rescues. [11]

At the height of the storm, strong winds downed trees and power lines causing over 215,000 power outages in Sydney, the Central Coast, and the Hunter Region. Four major power lines have since been restored, though approximately 155,000 power outages remain in effect as of Thursday April 23.

Sydney saw 38 hours with sustained winds over 30 miles per hour and frequent gusts over 50 mph from mid-afternoon 20 April to early morning on 22 April. [10] The storm disrupted electricity to 215,000 customers, the largest outage since the 2007 east coast low. [12]

3rd "catastrophe" of year following Cyclone Marcia and the 2015_Sampson_Flat_bushfires of South Australia by the Insurance Council of Australia. [13]

Erosion

Bondi Beach sand blown from the beach onto the shore and bury skatepark. Coogee Beach 12 large earth movers, two vacuum trucks and a crew of 35 worked to restore the beach, Up to 2,500 tonnes of sand had been violently churned up and displaced by Sydney's record-breaking storms, stripping the beach and dumping 400-500 tonnes over nearby parks and roads. [14] Narrabeen Beach saw erosion described as 1 in 20 year event, as the beach eroded some 25m landwards/ The 14.9-metre wave recorded offshore eclipsed the previous high of 14.1 metres set during the 2007 east coast low /offshore buoy also recorded 30 consecutive hours of significant waves heights above six metres, up until 1am on Wednesday. That length easily beat the previous record of 24 hours set during the Mother's Day storm of May 1997, Mr Couriel said, citing data going back to 1987. [15]

Rainfall and flooding

According to the Bureau of Meteorology (BoM), at the height of the storm on Monday April 20, rainfall accumulations of 4.7 in (120 mm) were recorded over a period of 24 hours across the affected areas, including Sydney, while rainfall accumulations reached 12.2 in (312 mm) in Dungog over the same time period. Twelve areas along the NSW coastline, between the cities of Newcastle (pop. ~ 308,000) and Sydney, have been declared natural disaster zones, which means that hardship payments and emergency assistance can be deployed quickly to these areas. In the south-western districts of Sydney, over 200 homes were evacuated as heavy rainfall caused the Gorges River to burst its banks, flooding the surrounding towns southwest of Sydney.

225mm rain fell in Sydney over the last 2 days, the wettest 2-day period since and east coast low on 7-8 August 1998. [10]Wettest April in 26 years in Sydney with almost triple the average monthly rainfall, Sydney saw the most rain over two day period in 17 years. [11]

Reports indicate that the town of Dungog was one of the worst areas affected by flooding, with dozens of homes damaged and four homes destroyed. The town of Dungog (pop. ~2,100), located approximately 100 mi (160 km) north-northeast of Sydney appears to the worst area affected by flooding, with dozens of homes damaged and four homes destroyed. Homes were swept away as over 12 inches (312 millimeters) of rain in just 24 hours swamped the town of about 2,100 residents 135 miles north of Sydney, according to the Australian Bureau of Meteorology (BoM)."To give you a sense of the size and scope, in Dungog, there's more rain that has come down in the last 24 hours than they have seen in a 24-hour period for the past century," according to NSW premier Mike Baird. [10] local government urged residents of Dungog to evacuate to a local high school, if possible, due to the severe flooding. [10]

Transport

Dozens of international flights to Sydney Airport were diverted to Brisbane and many outbound flights faced disruptions, as strong winds created hazardous flying conditions. Large swells caused ferry services at Sydney Harbour to be disrupted, with some cruise liners and ships waiting up to 48 hours to dock, as the harbour closed.

Newcastle port, the world’s biggest marine coal export terminal, was closed due to the storm. [16]

Manly_ferry_services, [12] Services on the South_Coast_railway_line,_New_South_Wales South Coast train line have also been cancelled between Oak Flats and Kiama. [12] Hunter line closed

Over 180 schools in the region closed during the storm.

Aftermath

The insurance industry quickly declared a "catastrophe" after receiving a deluge of claims from across the Sydney metropolitan area, the NSW Central Coast of and the Hunter.

The Insurance Council of Australia reported that over 24,400 claims relating to the storms have been lodged across NSW, mostly relating to low-level property damage from water and wind damage, and damage to cars, though some claims relating to severe damage to houses and roofs and storm-water inundation have been lodged.

Initial losses of the order of $129 million were estimated. with the number likely to rise as policyholders continue to claim. [17]

The insurance claims though are short of some other extreme weather events Sydney has previously experienced, following the 1999 Sydney hailstorm the industry paid out claims worth $1.7 billion, which the Insurance Council of Australia says would be equivalent of $4.3 billion in today's dollars.

Another feature of east coast low development is the tendency for clustering of events when conditions remain favourable. For example, near Brisbane, almost one third of events occur within 20 days of a preceding event. [22]

Correlations of east coast cyclones with the interannual differences of the El Niño–Southern Oscillation indicate a strong preference for these storms to form just after a large swing from negative to positive Southern Oscillation index values and especially between swings from negative SOI the year before and positive SOI the year after. This suggests a preference for formation of east coast cyclones between extreme events of the Southern Oscillation Index. [23]

Australian Bureau of Meteorology http://media.bom.gov.au/releases/161/bureau-monitoring-the-potential-for-another-east-coast-low-to-develop/ 28 April The bureau’s NSW weather services manager, Andrew Treloar, said significant rainfall could bring a fresh round of flooding. It was expecting “less prolonged gales” than in the previous storm, but further wind damage could not be ruled out. http://www.theguardian.com/australia-news/2015/apr/28/more-nsw-storms-coming-as-heavy-rain-and-wind-forecast-for-northern-coast

Water Vapour 5 May 2015

Denmark saw torrential rain mainly across Jutland saw 15 to 20mm of rain fall in 30 minutes in some locations. [4] Varmen trækkes op af et kraftigt lavtryk nær De Britiske Øer. Det pumper varm og fugtig luft fra Sydeuropa op til vore breddegrader.

Der er endnu noget usikkert, hvor meget vand, der bliver vredet ud af de kraftige byger, men generelt falder der et sted mellem 10 og 20 mm. I de sydvestlige og østlige egne af landet kan man lokalt opleve op mellem 25-35 mm, og dermed er der risiko for lokale skybrud eller for kraftig regn.

Såfremt der skulle blive målt skybrud tirsdag, vil det være første gang i 2015, men helt sikkert ikke sidste gang. [5]
