Forecast:

Tropical storm conditions are expected within the tropical storm warning areas by Saturday morning. Tropical storm conditions are possible in the tropical storm watch area in the northeastern Leeward Islands by Saturday morning and in the watch area in the Virgin Islands by Saturday night.
Rainfall: Jose is expected to produce total rain accumulations of 3 to 5 inches in the Leeward Islands from Guadeloupe to Anguilla, with isolated maximum amounts of 8 inches. Jose is also expected to produce total rain accumulations of 1 to 3 inches over the Virgin Islands and Dominica. This rainfall will maintain any ongoing flooding and may cause additional life-threatening flooding.
Storm Surge: A dangerous storm surge will raise water levels by 2 to 4 feet above normal tide levels along the immediate coast in the hurricane warning areas. Near the coast, the surge will be accompanied by large and destructive waves.
Surf: Swells generated by Jose are affecting portions of the Leeward Islands. These swells are expected to continue for a couple of days, and could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
