The Weather Channel: Shower and thunderstorm activity associated with a large low pressure area located about 1150 miles east-southeast of the Windward Islands has increased and become a little better organized since yesterday.
Environmental conditions are expected to be conducive for gradual development, and a tropical depression is likely to form later this week while the low moves westward to west-northwestward at 15 to 20 mph. Interests in the Windward Islands should monitor the progress of this system.
The National Hurricane Center has tentatively scheduled the first Hurricane Hunter mission into the system for Tuesday afternoon.
The system will arrive in the Windward Islands, bringing showers, some locally heavy rain and gusty winds by Wednesday, according to our latest forecast.
The National Hurricane Center has given this system a high chance for formation into a tropical depression over the next 2 to 5 day period as it nears the Lesser Antilles into the Caribbean. If formed, the next named storm in the Atlantic would be Matthew.
It should be noted this disturbance is starting out at a fairly low latitude, south of 10 degrees. Therefore, showers and gusty winds are expected in such locations as St. Vincent and the Grenadines, Grenada, Trinidad and Tobago, perhaps even coastal Venezuela later this week.
SLUMET: A tropical wave will continue to cause cloudiness, showers and isolated thunderstorms over the Lesser Antilles today. A broad area of low pressure associated with a tropical wave, is located over the central tropical Atlantic and is moving westward near 20 mph or 31 km/h. Interests in Saint Lucia and the Lesser Antilles are asked to monitor the progress of this system and take the necessary precautions.
