FORECAST FOR THE LESSER ANTILLES
Over the extreme northern portion of the Lesser Antilles, it will be generally cloudy with some scattered showers and isolated thunderstorms. Elsewhere, skies will be partly cloudy to cloudy with a few scattered showers and a chance of isolated thunderstorms.

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

At 5:00 pm today, the centre of Hurricane Jerry was located near latitude 19.6 North, longitude 62.0 West or about 120 miles or 195 kilometres northeast of the Northern Leeward Islands. Jerry is moving toward the west-northwest near 18 mph or 30 km/h. On the forecast track, the centre of Jerry will move north of the Northern Leeward Islands later today, pass well north of Puerto Rico on Saturday, and be well east-northeast of the southeastern Bahamas on Sunday and turn northward on Monday.

Maximum sustained winds have decreased to near 80 mph or 130 km/h with higher gusts. Some weakening is forecast overnight but Jerry could re-strengthen early next week.

Interests around the Northern Leeward Islands should monitor the progress of Jerry. Hurricane Jerry poses no threat to Saint Lucia at this time.

Shower and thunderstorm activity associated with a tropical wave located several hundred miles east of the Windward Islands has increased during the past 24 hours. The wave is expected to move quickly westward at about 20 mph during the next few days, and some development is possible while it approaches and moves across the Windward Islands this weekend.

A 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.
