SURFACE WINDS: Today through Tuesday midday: Northeast to east southeast with a light to gentle breeze of 04 to 09 mph, becoming calm and variable at times.
SYNOPSIS:
The proximity of a broad surface trough, northeast of the local region will result in light to calm winds for the next several days. As a result, due to daytime heating and available moisture, afternoon showers along with a low to moderate chance of isolated thunderstorms are expected across the local area.
Seas are expected to peak near 6 feet during the next several days.
STATE OF THE SEA: Slight to Moderate WAVES/SWELLS: 4 to 6 feet
SPECIAL FEATURES: A broad area of low pressure located about 350 miles east-northeast of the northern Leeward Islands is producing disorganized showers and thunderstorms with winds of around 30 mph on its northeast side. Some gradual development of this system is expected, and a tropical or subtropical depression could form during the next couple of days while it moves northwestward and then northward over the open Atlantic. After that time, upper-level winds are expected to become less conducive and the disturbance is forecast to merge with a frontal system after midweek, so additional development is not expected.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
This system is not forecast to have a direct impact on St Maarten.
The Meteorological Department will continue to monitor this system.
OUTLOOK through Wednesday midday: Partly cloudy, becoming cloudy at times with isolated showers.
