Typhoon Chaba, known in the Philippines as Tropical Depression Caloy was a Category 1-equivalent typhoon that struck South China after affecting the Philippines as a tropical depression. The third named storm and second typhoon of the 2022 Pacific typhoon season, Chaba originated from a low-pressure area west of Luzon and developed into a tropical depression on June 28.[1][2] Chaba made landfall in southwestern Guangdong province, China; at least 12 people died when an offshore crane vessel split in half during the storm and sank.

A low-pressure area west of Luzon developed into a tropical depression on June 28.[3][4] At 20:00 PHT (12:00 UTC), the PAGASA had recognized the storm's development into a tropical depression, began issuing advisories, and named the system Caloy.[5] The following day, the JTWC issued a TCFA for the system.[6] Caloy remained almost stationary in the South China Sea before slowly moving northwestwards, eventually leaving the Philippine Area of Responsibility by 15:00 UTC.[7][8] As the PAGASA issued its last bulletin on the tropical depression, the JTWC began issuing warnings for the storm and was given the designation 04W.[9][10] Later, the Japan Meteorological Agency upgraded Caloy into a tropical storm, naming it Chaba.[11] Chaba continued to intensify in the South China Sea, later being upgraded into a severe tropical storm east of Hainan.[12] Typhoon Chaba's outer rainbands produced at least three tornadoes, which impacted Shantou, Chaozhou, and Foshan.[13][14][15] On July 1 at 21:00 UTC, the JTWC upgraded Chaba to a typhoon,[16] with the JMA doing the same 3 hours later on July 2 at 0:00 UTC.[17] Later that day at 07:00 UTC, it made landfall on Maoming.[18] Shortly after its landfall, both the JMA and the JTWC assessed that Chaba lost typhoon status, downgrading Chaba to a severe tropical storm and to a tropical storm respectively.[19][20] The JTWC then issued their final warning on Chaba at 15:00 UTC.[21] Shortly after, the JMA downgraded Chaba to a tropical storm;[22] it was further downgraded to a tropical depression on July 3 at 06:00 UTC.[23]

Impact

160 nautical miles (300 km; 180 mi) southwest of Hong Kong, the Fujing 001, a crane vessel tasked in assisting with the construction of an offshore wind farm, split in half and quickly sunk—leaving 26 crew members missing.[24][25] Three of the 30 crew members were rescued, seen in a video published online by the Hong Kong Government Flying Service.[26] Another person was rescued by July 4, bringing the total number of people rescued to four. Twelve bodies from the ship were recovered.[25] More than 400 flights were suspended in Hainan; one person was injured in Macau.[27]
