Some of these showers may be heavy and could lead to street-flooding and rock-slides. Therefore, residents and visitors of vulnerable and flood-prone areas are advised to use precautions. 

Slight to moderate seas, peaking up to 6 feet are expected through the next few days. Small craft operators and swimmers should continue to exercise caution.

1.   At 11am, the center of Tropical Storm Franklin was located near 15.0N 70.1W or about 510 miles southwest of St. Maarten. Franklin is moving towards the west at 6 mph, away from St. Maarten. Maximum sustained winds are near 50 mph with higher gusts. Cloudiness, possible thunderstorms with occasional gusts, and up to about 1 inch of rainfall remains possible across the local area through the next 24 or so hours.
