STORM SURGE: A dangerous storm surge will raise water levels by as much as 3 to 5 feet above normal tide levels in areas of onshore winds in the central and northwestern Bahamas. Storm surge will raise water level by as much as 1 to 3 ft above normal tide levels in the southeastern Bahamas.
WIND: Tropical storm conditions will continue to spread across portions of the Dominican Republic, Haiti, the southeastern Bahamas and Turks and Caicos tonight and early Friday.

From Friday night through Monday:
South Florida into eastCentral Florida: 2 to 4 inches, with isolated maximum totals of 6 inches.

These swells will spread along the coast of Cuba and into the central and northwestern Bahamas over the next day or two. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.
