Strong tropical wave prompts flash flood warnings
MIAMI - A strong and fast-moving tropical wave over the eastern Caribbean Sea resulted in flash flood warnings being issued for the Lesser Antilles, the Virgin Islands, and Puerto Rico though Monday night.
According to the National Hurricane Center (NHC) in Miami, as of 2 pm EDT on Sunday there were no signs of a closed surface circulation but gradual development of the system is possible during the next day or so. The chance of tropical cyclone formation should increase to 70 percent after the wave reaches the western Caribbean Sea in a couple of days.
The disturbance was expected to cause locally heavy rains and gusty winds over portions of the Lesser Antilles, the Virgin Islands, and Puerto Rico on Sunday and Monday. The US National Weather Service, San Juan Forecast Office, has extended the flash flood watch to 6 pm Monday for the US Virgin Islands and Puerto Rico.
Rainfall totals are expected to be between 2 and 4 inches with locally higher amounts are possible with this strong tropical wave. Localized flash flooding and landslides are likely in areas of persistent heavy rainfall.
These conditions should spread westward across the central Caribbean Sea and reach Hispaniola by Monday and Jamaica and Cuba by Tuesday.
Interests in these areas and elsewhere in the Caribbean Sea should continue to monitor the progress of this system.
