DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM EDT (0300 UTC), the eye of Hurricane Irma was located
near latitude 21.3 North, longitude 72.4 West. Irma is moving toward
the west-northwest near 16 mph (26 km/h), and this motion is
expected to continue for the next day or two 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 continue to
move westward away from the Turks and Caicos Islands and toward
the southeastern Bahamas overnight. The core of the hurricane will
then move between the north coast of Cuba and the Bahamas during the
next day or two.
Maximum sustained winds are near 165 mph (270 km/h) with higher
gusts. Irma is a 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 75 miles (120 km) from
the center, and tropical-storm-force winds extend outward up to 185
miles (295 km).
The estimated minimum central pressure is 920 mb (27.17 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...
Jupiter Inlet to Bonita Beach, including Florida Keys...5 to 10 ft
Bonita Beach to Venice...3 to 5 ft
Jupiter Inlet to Sebastian Inlet...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 expected to continue within the
hurricane warning area in Haiti tonight. Hurricane conditions are
occurring on the Turks and Caicos Islands. Tropical storm and
hurricane conditions are spreading across the southeastern Bahamas
and will move into the central Bahamas by early Friday. Hurricane
conditions are expected within the hurricane warning area along the
north coast of Cuba late Friday and Saturday. Hurricane conditions
are expected in the northwestern Bahamas Friday night and Saturday,
and in portions of southern Florida and the Florida Keys late
Saturday.
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 Sunday evening:
Northeast Puerto Rico and the British and U.S. Virgin Islands...
additional 2 to 4 inches, isolated 6 inches.
Northern Dominican Republic and northern Haiti...additional 3 to 6
inches.
Southern Dominican Republic and southern Haiti...additional 1 to 2
inches.
Much of the Bahamas and Turks and Caicos...8 to 12 inches, isolated
20 inches.
Andros Island and Bimini, Bahamas...12 to 16 inches, isolated 25
inches.
Eastern and central Cuba...4 to 10 inches, isolated 15 inches.
Southeast Florida and the upper Florida Keys...8 to 12 inches,
isolated 20 inches
Lower Florida Keys...2 to 5 inches.
Central Florida into northeast Florida and coastal Georgia...3 to 6
inches, isolated 10 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.
