Part of the 2023 Pacific typhoon season

Tropical Storm Jelawat, known in the Philippines as Tropical Storm Kabayan, is a late-season tropical storm that traversed through Mindanao. The seventeenth and last named storm of the 2023 Pacific typhoon season, Jelawat developed from a low-pressure area near the Philippine Area of Responsibility on December 15. Less than two days later, the depression would intensify into a tropical storm, resulting in it being named Jelawat by the JMA. Jelawat would slightly strengthen before making landfall in Manay, the Philippines on December 18.

triangle Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

On December 13, the JTWC began to monitor an area of convection approximately 1,154 km (717 mi) east-southeast of Yap. The disturbance had convection scattered over the west and south side of a broad LLCC. [1] Later that day, the JMA began monitoring the disturbance, labeling it as a low-pressure area. [2] Conditions for tropical cyclogenesis remained marginally conducive with sea surface temperatures of 30–31 °C (86–88 °F) and low vertical wind shear subdued by westward outflow aloft. [3] On December 15, the JMA recognized the system as a tropical depression. [4] The next day, the depression would cross into the Philippine Area of Responsibility, resulting in PAGASA naming the depression Kabayan. [5] On December 17, the system had intensified into a tropical storm, earning the name Jelawat from the JMA. [6] JTWC later recognized as a tropical depression, designated as 18W. Later that day, Jelawat would make landfall in Manay, Davao Oriental, weakening into a tropical depression. [7]

Preparations and impacts

Before Jelawat made landfall, thousands of people would be evacuated in centers across Mindanao while shipping vessels would be prohibited from sailing. [8]
