SYNOPSIS:  

A loose pressure gradient will maintain mostly light winds across the region. Weak instability and available moisture in the wake of a tropical wave, may cause isolated showers and a chance of isolated thunderstorms tonight. A relatively more stable air mass will filter into the region slightly lowering the chances of showers thereafter.  

Seas are expected to remain slight to moderate for the next few days.

STATE OF THE SEA:  Slight to moderate           WAVES/SWELLS: 3 to 5 feet

SPECIAL FEATURES: A weak area of low pressure, associated with a tropical wave located about 900 miles east of the Lesser Antilles is producing disorganized showers and thunderstorms. Although some slight development of this system is possible today or Wednesday, by Thursday, upper-level winds are forecast to become unfavorable for tropical cyclone formation. This disturbance is expected to move slowly westward across the tropical Atlantic Ocean for the next several days.

* Formation chance through 48 hours...low...20 percent.

* Formation chance through 5 days...low...20 percent.


A tropical wave located between the west coast of Africa and the Cabo Verde Islands is expected to move quickly westward during the next several days. Some slow development is possible over the weekend when the system is a few hundred miles east of the Windward Islands.

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 5 days...low...20 percent.

The Meteorological Department of St. Maarten will continue to monitor the progress of these systems and update the public accordingly.

OUTLOOK through Thursday evening: Partly cloudy with isolated showers possible.
