Potential Tropical Cyclone Twenty-Two was a tropical disturbance that caused destructive flash floods in Hispaniola, Jamaica, and Cuba in mid-November 2023.
Meteorological history
editA broad area of low pressure formed over the southwestern Caribbean Sea on November 14.[2] The disturbance became more organized on November 16. Satellite images and data gathered during a U.S. Air Force Reserve hurricane hunter flight showed that the system had a closed yet elongated circulation, but there was not a well-defined low level center. At 21:00 UTC on November 16, the NHC designated the system Potential Tropical Cyclone Twenty-Two.[3] The system was unable to organize further due to persistent high wind shear, and only produced near gale-force peak winds of 30–35 mph (45–55 km/h).[4] At 03:00 UTC on November 18 the NHC issued their final advisory on the system, then located between Cuba and Jamaica, after it seemed likely that the disturbance would neither develop nor produce tropical storm-force winds.[3]
Impact
editJamaica
editFlash flood warnings were issued for ten parishes, including Westmoreland, Saint Thomas, Portland, and Saint Mary parishes. The remainder of the island was placed under a Flash Flood Watch.[5] The disturbance brought heavy rainfall to Jamaica, peaking at 12.4 in (315.4 mm) at the Norman Manley International Airport in Kingston.[6] Several trees and power lines were downed, leaving 14,000 customers without electricity. The Jamaican Defence Force rescued 24 people from floodwaters.[7]
