the west-northwest near 13 mph (20 km/h). A continued
west-northwest to northwest motion is expected during the next
couple of days. On the forecast track, the core of Jose will pass
close to or just east of the northern Leeward Islands today.

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 24 hours. Afterward, gradual weakening
is expected to occur.

WIND: Hurricane conditions are expected within the hurricane
warning area today. Hurricane conditions are also possible within
the hurricane watch area today. Tropical storm conditions are
expected within the tropical storm warning areas by this morning.
Tropical storm conditions are possible in the tropical storm watch
area in the northeastern Leeward Islands by this morning and in the
watch area in the Virgin Islands by tonight.
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
