Tropical Storm Bebinca (2024)

This article is about the 2024 tropical storm. For other storms of the same name, see List of storms named Bebinca and List of storms named Ferdie.

Severe Tropical Storm Bebinca, known in the Philippines as Tropical Storm Ferdie, is a tropical cyclone which affected multiple islands in the Pacific Ocean. The thirteenth named storm of the annual typhoon season, Bebinca formed from atmospheric convection 385 km (239 mi) east-northeast of Kosrae, was upgraded to a tropical storm by the Japan Meteorological Agency on September 10, and was named Bebinca, before turning west-northwest due to interaction with an upper vortex; by September 13, as it entered the Philippine Area of Responsibility, the Philippine Atmospheric, Geophysical and Astronomical Services Administration renamed it Ferdie.

Severe Tropical Storm Bebinca emerged from an area of atmospheric convection 385 km (239 mi) east-northeast of Kosrae on September 5.[1] The system, characterized by a disorganized wave in the easterlies, featured intense deep convection over a large area, supported by favorable conditions for tropical cyclogenesis,[2] such as warm sea surface temperatures of 28–29 °C (82–84 °F), low vertical wind shear and excellent poleward outflow.[3] At 02:30 UTC on September 9, the United States Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert, noting that the system had become well-defined with formative banding in the eastern quadrants.[4] A few hours later, both the Japan Meteorological Agency (JMA) and the JTWC followed suit and upgraded the tropical depression, with the latter designating the system as 14W.[5][6]

On September 10, the depression intensified into a tropical storm and was named Bebinca by the JMA,[7] as it consolidated with a central dense overcast feature obscuring its circulation center while tracking near Guam,[7] and subsequently turned west-northwestward due to interaction with an upper vortex.[8] Guam radar imagery showed a well-defined surface circulation, with curved convective bands extending southward from the circulation center and wrapping around the northern part of the system into its western periphery.[9] Around 00:00 UTC on September 11, the JMA upgraded it to a severe tropical storm, citing Dvorak technique—a method of determining a tropical cyclone's intensity based on satellite appearance.[10] On September 13, the JMA reported that the storm had weakened to a tropical storm due to its near-surface circulation being fully exposed and its banding being fragmented along the northern edge,[11] with a broad tail of deep monsoonal flow and a tropical upper tropospheric trough cell to the west continuing to infuse dry air into the storm's mid-level core.[12] By 06:00 PHT (10:00 UTC), Bebinca had entered the Philippine Area of Responsibility, and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) subsequently assigned it the name Ferdie.[13]

Just a few hours after Bebinca entered the Philippine Area of Responsibility, Bebinca left, still continuing heavy rains across the country.[14] Bebinca is expected to intensify into a typhoon, passing through China and southern Japan. [15]

Preparations and impact

edit

Philippines

edit

PAGASA stated that the Southwest monsoon, locally called Habagat, will happen when the storm enters the Philippines, and will continue after the storm exits the Philippines. Bebinca is also predicted to bring heavy rains across the northern portion of the Philippines. Thunderstorms are also expected in the rest of Luzon and Metro Manila.[16] PAGASA also predicts that the storm will intensify into a typhoon, brining flash floods into the country.[17] PAGASA stated that the storm will bring 1.5–3.5 metres (1.6–3.8 yards) high flash floods to Palawan, Western Visayas, Negros Island Region, Central Visayas, Eastern Visayas, Caraga, Northern Mindanao, Zamboanga Peninsula and the Davao Region. Small waterborne vehicles, like Motor bancas were advised to take precautionary measures because of the storm.[18] Due to a paper signed by the vice president Sara Duterte, all classes in September 14 were closed in areas where the red and orange rainfall warnings persist.[19]

The province of Antique evacuated 545 families because of the storm, also suspending classes, in all levels in the province. The province provided food packs for the evacuees.[20]

Guam

edit

When the storm passed the Pacific Ocean, Guam was affected, leading to storm warning all across the country. After the storm passed the country, Guam hoisted Readiness Three, a small warning which allows people to go to work, not affecting businesses and the national government.[21]

Taiwan

edit

As a way of preparation, weather researchers used AI to predict the storm path. The program was also used for Typhoon Gaemi, successfully working a week before the hit.[22] The storm is predicted to bring heavy rains to Taiwan, with possible thunderstorms occurring.[23]

East Asia

edit

The storm is forecast to bring heavy rains to Japan, with high winds recorded at the Kadena Air Base and Okinawa.[24] The storm also is forecast to pass through Okinawa.[25][26][27] A rebook policy was made by Delta Air Lines, which suspended all flights coming from Shanghai from September 14 to 16.
