A FLOOD ADVISORY IS IN EFFECT FOR ST. MAARTEN
FOR THE NEXT 12 HOURS

A tropical wave is currently passing through the Eastern Caribbean, coupled with favorable upper level conditions over our local area and the accompanying surge of moisture will cause unsettled weather. As a result, cloudy skies, breezy conditions isolated showers, some of which could be heavy, and isolated thunderstorms are expected today.

Due to already saturated soils from persistent rainfall and additional rainfall that is expected today, a flood advisory is now in effect. Therefore, motorists and persons living in low-lying areas should remain vigilant due to possible street flooding and localized flooding.

After the wave exits the region, the Saharan dust and Atlantic high pressure system will reestablish across the local area and limit significant precipitation.
