Tropical Storm Kong-rey, also known in the Philippines as Tropical Storm Leon, is an active tropical cyclone in the Western Pacific Ocean. The twenty-first named storm of the 2024 Pacific typhoon season, Kong-rey formed from an area of disturbance located southeast of Guam on October 24.
Meteorological history
editOn October 22, a low-pressure area was formed southeast of Guam. Two days later, the JMA issued warnings as the disturbance became a tropical depression because of a marginal environment characterized by low wind shear, moderate equatorward outflow, and warm sea surface temperatures.[1] However, limited firmness of the storm's structure prevented it from growing.[2] At 03:00 UTC, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA) for the system, with a weakly defined low-level circulation center but strong winds now wrapping the center.[3] Following this, the JTWC designated another area of convection as Invest 99W north of the system, with a low chance of forming. Early the next day, the storm grew over the past hours,[4] the Japan Meteorological Agency (JMA) also upgraded the depression to a tropical storm, gaining the name Kong-rey.[5]
The JTWC canceled the TCFA for the southern system but started to issue warnings for the northern system as a depression and designated it as 23W. The system had a partially obscured low-level circulation center (LLCC) with a single band of convection.[6] On 12:00 UTC the same day, dry air caused the storm to maintain its' intensity.[7] At 07:30 PM PHT (11:30 UTC) on October 26, Kong-rey entered the Philippine Area of Responsibility and was assigned the name Leon by PAGASA.[8] On 9:30 UTC the next day, the JTWC found two LLCCs inside the storm.[9] After a day of maintaining its' intensity,[10] the storm finally underwent intensification.[11] On October 28, the storm officially became a severe tropical storm by PAGASA.[12][13] The storm is expected to undergo rapid intensification by PAGASA.[14]
Preparations and impact
editPhilippines
editThe storm is currently unlikely to affect weather conditions in the Philippines, though rainfall is possible.[15][16] According to Meralco communication head Joe Zaldarriaga, Meralco is preparing for the storm.[17] The storm is expected to affect northern Luzon.[18] The government of Albay also prepared for the possible impact of Kong-rey.[19] On 23:00 Philippine Time (15:00 UTC), PAGASA issued Tropical Storm Warning Signal No. 1 to portions of Cagayan, Isabela, and Catanduanes.[20] The next day, PAGASA included the entirety of Batanes, Ilocos Norte, Abra, Apayao, and Kalinga. PAGASA also included the entirety of Cagayan and Isabela, with portions of Quirino and Aurora.[13]
