Maximum sustained winds are near 150 mph (240 km/h) with higher gusts. Jose is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuation in intensity, up or down, could occur during the next day or so. Gradual weakening is expected after that.

Wind: Hurricane conditions are likely within the hurricane warning area on Saturday. Hurricane conditions are also possible within the hurricane watch area on Saturday. 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.
