SYNOPSIS: A relatively stable atmosphere will restrict significant shower activity across the region. However, a brief shower remains possible. Meanwhile, light concentrations of Saharan dust will affect air quality, while hot and humid conditions persist. Stay hydrated and keep to the shade as much as possible. Long period northerly swells will maintain elevated seas through the next 12 or so hours, before gradually subsiding. Small craft operators and swimmers should exercise caution.
STATE OF THE SEA: Moderate to rough WAVES/SWELLS: 4 to 8 feet
SPECIAL FEATURE: A vigorous tropical wave (invest 98L) that recently affected the Eastern Caribbean has a medium to high (50 to 80%) chance of formation in the next 7 days. A tropical depression is likely to form by the middle to latter portion of this week in the central Caribbean Sea. The Meteorological Department of St. Maarten will continue to monitor the Atlantic and update the public accordingly.
OUTLOOK through Wednesday morning: Partly cloudy with light haze and isolated showers possible.
