The Antigua and Barbuda Meteorological Services has extended the flash flood watch for the BVI until 4:00a.m. tomorrow (Thursday August 25) as they predict periods of scattered showers (some of which may be moderate to heavy), isolated thunderstorms and gusty winds to affect the Territory tonight into tomorrow.
Squalls to tropical storm force can also be expected across the Territory, as the strong tropical wave (Invest99L) moves westward across the northern Leeward Islands.
Reports from an air force reconnaissance aircraft and surface observations indicate that the system still lacks a well-defined circulation, but it nevertheless is producing tropical-storm-force winds in squalls over the northernmost Leeward Islands and adjacent waters.
Although upper-level winds are expected to be only marginally conducive for additional development, this system could become a tropical storm or tropical depression at any time during the next couple days. Forecasters have indicated that Invest 99L has a 60% chance of developing into a tropical storm in 48 hours (2 days).
Regardless of development, strong winds, heavy rains, and possible flash floods are expected to occur over portions of the Leeward Islands.
Due to the approaching strong tropical wave, sea conditions are becoming very hazardous as a result The Antigua and Barbuda Meteorological Services has issued small craft and sea bather warnings. Sea conditions are moderate to rough with waves 2.1 to 3 metres or 7 to 10 feet.
Boaters are therefore advised to monitor the tropical wave and take the necessary precautionary steps to secure their vessels. Residents are encouraged to refrain from exploring the rocks along the shoreline until after conditions return to normal.
Residents are also advised to take precautionary steps to safeguard life and property in the event of flash flooding.
Please continue to monitor the system for any sudden change in its intensity that may warrant specific watches or warnings being issued. The Department of Disaster Management will continue to monitor the system and advise the public.
