Showers and thunderstorms associated with a broad area of low pressure located about 700 miles east-southeast of the Windward Islands are gradually becoming better organized.
Environmental conditions remain conducive for development, and a tropical depression is likely to form during the next day or two while the system moves westward to west-northwestward near 20 mph. Interests in the eastern and central Caribbean Sea, including the northern coast of South America, should monitor the progress of this system.
Regardless of development, heavy rains and strong gusty winds, possibly to tropical storm force, are expected to spread over the Windward Islands and portions of the southern Lesser Antilles beginning late Tuesday or Wednesday.
An Air Force Hurricane Hunter aircraft is scheduled to investigate this disturbance on Tuesday afternoon.
* Formation chance through 48 hours…high…80 percent
* Formation chance through 5 days…high…90 percent
The St. Vincent and the Grenadines Meteorological Office in a bulletin said, a tropical depression or tropical storm could form by the time the system approaches St. Vincent and the Grenadines, early Wednesday morning.
