TROPICAL WEATHER OUTLOOK
Moisture and instability in the lower atmosphere over the Eastern Caribbean will cause some scattered showers and isolated thunderstorms over the islands during the forecast period.

A tropical wave located several hundred miles east of the Windward Islands continues to produce a large area of showers and thunderstorms. The wave is forecast to move quickly westward to west-northwestward at 15 to 20 mph for the next day or two, crossing the Windward Islands on Sunday. Although the system is currently disorganized, environmental conditions appear to be conducive for some development and a tropical depression could form later this weekend or early next week. A Hurricane Hunter aircraft is scheduled to investigate this system this afternoon. Regardless of development, heavy rainfall is possible over much of the Lesser Antilles over the weekend, and interests on those islands and Puerto Rico should monitor the progress of this disturbance.

At 11:00 am today, the centre of Tropical Storm Jerry was located near latitude 22.0 north, longitude 65.0 west or about 260 miles or 415 kilometres north northeast of San Juan Puerto Rico.

Tropical Storm Jerry poses no threat to Saint Lucia.

Another tropical wave located over the eastern Tropical Atlantic is moving westward near 15 mph or 24 km/h.

A third tropical wave is forecast to move off the west coast of Africa this weekend. Environmental conditions are expected to be conducive for development and a tropical depression or tropical storm is likely to form early next week while the wave moves westward across the Eastern Tropical Atlantic.
