A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. A warning is typically issued
36 hours before the anticipated first occurrence of tropical-storm-
force winds, conditions that make outside preparations difficult or
dangerous. In this case, for some of easternmost islands, the
hurricane conditions are expected within the next 12 to 24 hours.
Preparations to protect life and property should be rushed to
completion.
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area in this case within 36
hours.
A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.
Interests elsewhere in the Dominican Republic and Haiti, as
well as Cuba, the central and northwestern Bahamas, and Florida
should monitor the progress of Irma.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1100 AM AST (1500 UTC), the eye of Hurricane Irma was located
near latitude 16.8 North, longitude 58.4 West. Irma is moving toward
the west near 14 mph (22 km/h), and this general motion is expected
to continue today, followed by a turn toward the west-northwest
tonight. On the forecast track, the extremely dangerous core of Irma
is forecast to move over portions of the northern Leeward Islands
tonight and early Wednesday.
Reports from an Air Force Hurricane Hunter aircraft indicate that
the maximum sustained winds are near 180 mph (285 km/h) with higher
gusts. Irma is a an extremely dangerous category 5 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity
are likely during the next day or two, but Irma is forecast to
remain a powerful category 4 or 5 hurricane during the next couple
of days.
Hurricane-force winds extend outward up to 60 miles (95 km) from the
center and tropical-storm-force winds extend outward up to 160 miles
(260 km).
The latest minimum central pressure reported by reconnaissance
aircraft is 931 mb (27.50 inches).
HAZARDS AFFECTING LAND
———————-
STORM SURGE: The combination of a life-threatening storm surge and
large breaking waves will raise water levels by as much as 7 to 11
feet above normal tide levels along the coasts of the extreme
northern Leeward Islands within the hurricane warning area near and
to the north of the center of Irma. Near the coast, the surge will
be accompanied by large and destructive waves.
The combination of a life-threatening storm surge and the tide will
cause normally dry areas near the coast to be flooded by rising
waters moving inland from the shoreline. The water is expected to
reach the following heights above ground if the peak surge occurs at
the time of high tide…
British and U.S. Virgin Islands except St. Croix…7 to 11 ft
Northern coast of Puerto Rico…3 to 5 ft
Southern coast of Puerto Rico and St. Croix…1 to 2 ft
The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large and
destructive waves. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.
WIND: Hurricane conditions are expected within the hurricane
warning area in the Leeward Islands by tonight, with tropical storm
conditions beginning later today. Tropical storm conditions are
expected within the tropical storm warning area where hurricane
conditions are also possible. Hurricane conditions are expected
to begin within the hurricane warning area in the British and U.S.
Virgin Islands and Puerto Rico on Wednesday, with tropical storm
conditions beginning tonight.
Hurricane and tropical storm conditions are possible within the
watch area in the Dominican Republic, Haiti, the Turks and Caicos,
and the southeastern Bahamas by early Thursday.
RAINFALL: Irma is expected to produce total rain accumulations
of 8 to 12 inches with isolated maximum amounts of 18 inches across
the northern Leeward Islands. Irma is expected to produce total
rain accumulations of 4 to 10 inches with isolated maximum amounts
of 15 inches across northeast Puerto Rico and the British and U.S.
Virgin Islands, and amounts of 2 to 4 inches over southwest Puerto
Rico, the southern Leeward Islands, and Saint Croix. This rainfall
may cause life-threatening flash floods and mudslides.
SURF: Swells generated by Irma will affect the northern Leeward
Islands, Puerto Rico, and the U.S. and British Virgin Islands
during the next several days. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
In the tropical Atlantic the disturbed weather well to the east of the Lesser Antillies has organized into a tropical storm and we now have Tropical Storm Jose. Winds are 40 mph. Conditions favor gradual strengthening and Jose will probably become in hurricane as well as it moves toward the west or west northwest.

located near latitude 12.3 North, longitude 39.1 West. Jose is

movement toward the west or west-northwest at a slightly faster
rate of forward speed is expected during the next two days.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Some strengthening is forecast during the next 48 hours and Jose
could become a hurricane by Friday.
Tropical-storm-force winds extend outward up to 45 miles (75 km)
