the northwest near 13 mph (20 km/h). A continued 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 later today.

Hurricane Wind Scale. Some fluctuation in intensity, up or down,
could occur during the next 24 hours. Afterward, gradual weakening
is expected to occur.
Hurricane-force winds extend outward up to 35 miles (55 km) from

HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected within the hurricane
warning 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
1 to 3 feet above normal tide levels along the immediate coast in
the hurricane warning and tropical storm 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.
