SYNOPSIS:
A drier airmass is limiting the potential for significant precipitation today. However, hot and humid conditions will persist. Stay hydrated, seek shade, and keep cool whenever possible. Later tonight, a tropical wave is expected to move through the region, increasing moisture and instability. Consequently, increased shower activity and a heightened risk of thunderstorms are expected.
Seas are expected to remain slight to moderate.
STATE OF THE SEA: Slight to moderate WAVES/SWELLS: 3 to 5 feet
SPECIAL FEATURE: A broad area of low pressure (AL92) over the central tropical Atlantic currently has a high (90%) chance of development in the next 2-7 days. A tropical depression or storm is likely to form in the next day or two.
The Meteorological Department of St. Maarten will continue monitoring the Atlantic and provide updates accordingly.
