The St. Lucia Meteorological Office is advising residents to monitor the progress of a low pressure system east of the Lesser Antilles.
The low-pressure system is located about 530 miles east of the Lesser Antilles and is expected to develop as it moves slowly west-northwestward towards the Leeward Islands, the Met Office said.
A tropical wave associated with the low pressure area is moving westward near 23 mph or 37 km/h. Another tropical wave located over the eastern Atlantic is moving westward near 15 mph or 24 km/h.
“These systems are expected to begin affecting the Lesser Antilles late Thursday into Friday. Residents of the Lesser Antilles should monitor the progress of these systems,” the Met Office said in its 12 noon, August 20 weather report.
Tropical cyclone formation is not expected over the tropical Atlantic during the next 24 hours.
Meanwhile in its forecast for the Lesser Antilles for the next 24 hours, the Met Office said “partly cloudy skies, becoming cloudy at times with scattered showers and a chance of isolated thunderstorms” are expected.
