depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at

protect life and property from rising water and the potential for
other dangerous conditions.  Promptly follow evacuation and other
instructions from local officials.
A Storm Surge Watch means there is a possibility of life-

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 AM EDT (1500 UTC), the distinct eye of Hurricane Irma was
located near latitude 22.0 North, longitude 75.3 West. Irma is
moving toward the west-northwest near 14 mph (22 km/h), and this
motion is expected to continue for the next day or so with a
decrease in forward speed.  A turn toward the northwest is expected
by late Saturday.  On the forecast track, the eye of Irma should
move near the north coast of Cuba and the central Bahamas today and
Saturday, and be near the Florida Keys and the southern Florida
Peninsula Sunday morning.
Maximum sustained winds are near 150 mph (240 km/h) with higher
gusts.  Irma is a category 4 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 hurricane as it approaches Florida.
Hurricane-force winds extend outward up to 70 miles (110 km) from
the center and tropical-storm-force winds extend outward up to 185
miles (295 km).
The latest minimum central pressure reported by both Air Force
and NOAA Hurricane Hunter planes was 927 mb (27.38 inches).
HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  The combination of a dangerous 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...
SW Florida from Captiva to Cape Sable...6 to 12 ft
Jupiter Inlet to Cape Sable including the Florida Keys...5 to 10 ft
Ponce Inlet to Jupiter Inlet...3 to 6 ft
Venice to Captiva...3 to 6 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.
The combination of a life-threatening storm surge and large breaking
waves will raise water levels ABOVE NORMAL TIDE LEVELS by the
following amounts 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.
Turks and Caicos Islands...15 to 20 ft
Southeastern and central Bahamas...15 to 20 ft
Northwestern Bahamas...5 to 10 ft
Northern coast of Haiti and the Gulf of Gonave...1 to 3 ft
Northern coast of Cuba in the warning area...5 to 10 ft
WIND:  Hurricane conditions are occurring on the Turks and Caicos
Islands, with tropical storm and hurricane conditions ongoing in the
southeastern Bahamas.  These conditions will move into the central
Bahamas later today.  Hurricane conditions are expected within the
hurricane warning area along the north coast of Cuba late today and
Saturday.  Hurricane conditions are expected in the northwestern
Bahamas tonight and Saturday, and in portions of southern Florida
and the Florida Keys Saturday night or early Sunday.
Hurricane conditions are possible within the watch area in Florida
by Sunday, with tropical storm conditions possible by late Saturday.
RAINFALL: Irma is expected to produce the following rain
accumulations through Tuesday night:
Dominican Republic and Haiti...additional 1 to 4 inches.
Turks and Caicos...additional 2 to 4 inches.
Southern Bahamas and northern Cuba...10 to 15 inches, isolated 20
inches.
Southern Cuba...4 to 8 inches, isolated 12 inches.
Jamaica...1 to 2 inches.
The upper Florida Keys into southeast Florida...10 to 15 inches,
isolated 20 inches.
Lower Florida Keys...4 to 8 inches.
Eastern Florida northward into coastal Georgia...8 to 12 inches,
isolated 16 inches.
Western Florida peninsula...4 to 8 inches, isolated 12 inches.
Much of Georgia...South Carolina...and Western North Carolina...3 to
6 inches.
In all areas this rainfall may cause life-threatening flash floods
and, in some areas, mudslides.
SURF:  Swells generated by Irma are affecting Puerto Rico, the
Virgin Islands, the southeastern Bahamas, the Turks and Caicos
Islands, the northern coast of the Dominican Republic, and should
start affecting portions of the southeast coast of the United States
later today and tonight.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
