TROPICAL WEATHER OUTLOOK
A strong tropical wave located just east of the Windward Islands is carrying a large area of cloudiness, showers, and thunderstorms. A Hurricane Hunter aircraft has been investigating the system this afternoon and did not find a well-defined circulation. Although the system is currently not well organized, some gradual development is expected and a tropical depression could form later this weekend or early next week. The wave is forecast to move quickly westward for the next day or two, crossing the Windward Islands on Sunday. Cloudiness and showers on the forward edge of the system will start affecting Saint Lucia and the Windward Islands later this evening. Regardless of development, heavy rainfall and gusty winds will affect much of the Lesser Antilles over the weekend, and interests on those islands and Puerto Rico should monitor the progress of this disturbance.

Tropical Storm Jerry continues to move northwest away from our region…

At 5:00 pm today, the centre of Tropical Storm Jerry was located near latitude 23.0North, longitude 65.8 West or about 320 miles or 510 kilometres north of San Juan Puerto Rico. Jerry has maximum sustained winds of 65 mph or 100 km/h and is moving towards the northwest away from our region at about 14 mph or 22 km/h.

Another tropical wave located over the eastern Tropical Atlantic is moving westward near 20mph or 32 km/h.

A third tropical wave is expected to move off the west coast of Africa by Sunday.

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.
