According to the latest update from the Saint Vincent and the Grenadines Meteorological Office, the strong tropical wave is located about 550 statute miles (825 km) to the east of St Vincent and the Grenadines.
The system continues to track west to west-north-west at about 15 to 20 mph or 24 to 32 km/h. The Barbados Meteorological Services has analyzed the centre of the system to be near 11.5N, 53.0W.
Environmental conditions remain conducive for continued gradual development over the next 24 – 36 hours, and a tropical depression/tropical storm could form by late this afternoon or tonight. A tropical storm warning may be issued for St Vincent and the Grenadines any time once the system has been upgraded.
Regardless of tropical cyclone development, moderate to heavy showers, periods of rain, thunderstorms and winds gusting to storm force are likely to spread across the island late tonight into Wednesday.
Rainfall accumulations of 4 to 8 inches (100 to 200 millimeters) are possible with higher amounts likely in the more elevated areas. In addition, swells of 4 to 5 meters (12 to 15 feet) are expected in open water. This will prompt a warning for small craft and sea bathers for Tuesday night and into Wednesday.
