0 BRIDGETOWN, Barbados, Sunday August 25, 2019 – A tropical storm watch is now in effect for St Lucia and St Vincent and the Grenadines, while Barbados which was under a similar advisory earlier today is now under storm warning, with Tropical Storm Dorian getting closer and becoming more organized.
The National Hurricane Centre (NHC) said at 2 p.m. that the centre of the storm was 430 miles east-southeast of Barbados and Dorian continues to move westward at 14 miles per hour.
“This motion should continue through tonight. A turn toward the west-northwest is expected on Monday, with this motion continuing through Tuesday night. On the forecast track, the centre of Dorian is expected to be near the Windward Islands late Monday or early Tuesday and move into the eastern Caribbean Sea on Tuesday,” the NHC said.
Maximum sustained winds remain near 40 miles per hour with higher gusts, but some strengthening is forecast during the next 48 hours, and Dorian could be near hurricane strength by Tuesday over the eastern Caribbean Sea.
But before it intensifies into a hurricane, the Barbados Meteorological Services (BMS) said the centre of Dorian is expected to pass over or near Barbados late tomorrow.
It said sustained surface winds between 40 and 52 miles per hour with gusts to storm force are expected to spread across Barbados tomorrow afternoon and persist into Tuesday morning. There are also forecasts for pockets of moderate to heavy showers, periods of rain and scattered thunderstorms.
Additionally, rainfall accumulations of at least two to four inches are possible late tomorrow into Tuesday with isolated higher amounts.
“As a result, some flash-flooding is likely in low-lying areas thus, residents are urged to be on the alert and take all necessary precautions. Large easterly to south-easterly swells of 2.5 to 3.5 metres are also forecast to accompany the system,” the BMS said.
“Low-lying coastlines around the island will be particularly vulnerable at times of high tide. Large waves and dangerous rip-tides can be expected. These will create unsafe conditions for small-craft operators and fishermen. Sea-bathers and other users of the sea are also advised to stay out of the water.”
A high-surf advisory and small-craft warning will be in effect from noon tomorrow until 6 a.m. on Tuesday.
Meantime, the NHC said additional watches or warnings could be issued later today for portions of the Windward and Leeward Islands, according to the National Hurricane Centre (NHC) in Miami. Elsewhere, interests in Puerto Rico and Hispaniola should monitor the progress of Dorian.
A tropical storm warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours; while a tropical storm watch means tropical storm conditions are possible within the watch area, generally within 48 hours.
