At 800 PM EDT (0000 UTC), the center of Hurricane Irma was located
by NOAA Doppler radar near latitude 26.7 North, longitude 81.7 West.
Irma is moving toward the north near 14 mph (22 km/h), and a
north-northwestward motion with an increase in forward speed is
expected by tonight, with that motion continuing through Monday. On
the forecast track, the eye of Irma should move near or over the
west coast of the Florida Peninsula through Monday morning. Irma
should then move inland over northern Florida and southwestern
Georgia Monday afternoon.
Maximum sustained winds have decreased to near 105 mph (165 km/h)
with higher gusts. Although weakening is forecast, Irma is expected
to remain a hurricane at least through Monday morning.
Hurricane-force winds extend outward up to 80 miles (130 km) from
the center, and tropical-storm-force winds extend outward up to 220
miles (350 km).
The estimated minimum central pressure is 942 mb (27.82 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...
Cape Sable to Captiva...10 to 15 ft
Captiva to Ana Maria Island...6 to 10 ft
Card Sound Bridge through Cape Sable, including the Florida Keys...
5 to 10 ft
Anna Maria Island to Clearwater Beach, including Tampa Bay...
5 to 8 ft
North Miami Beach to Card Sound Bridge, including Biscayne Bay...
3 to 5 ft
South Santee River to Fernandina Beach...4 to 6 ft
Clearwater Beach to Ochlockonee River...4 to 6 ft
Fernandina Beach to Jupiter Inlet...3 to 5 ft
North of North Miami Beach to Jupiter Inlet...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 continuing across portions of the
southern Florida peninsula. Winds affecting the upper floors of
high-rise buildings will be significantly stronger than those near
ground level. Tropical storm and hurricane conditions are expected
to spread northward across the remainder of the warning areas
through Monday. Tropical storm conditions are expected in portions
of the warning area in the Northwestern Bahamas this evening.
RAINFALL: Irma is expected to produce the following rain
accumulations through Wednesday:
Western Bahamas...Additional 2 to 4 inches, isolated 6 inches.
The Florida Keys...Additional 3 to 6 inches with storm total amounts
from 15 to 20 inches, isolated 25 inches.
Western Florida peninsula...10 to 15 inches, isolated 20 inches.
Eastern Florida peninsula and southeast Georgia...8 to 12 inches,
isolated 16 inches.
The rest of Georgia, the eastern Florida Panhandle, southern and
western South Carolina, and western North Carolina...3 to 8 inches,
isolated 12 inches.
Southern Tennessee, northern Mississippi and much of Alabama...2 to
5 inches.
In all areas this rainfall may cause life-threatening flash floods.
TORNADOES: Tornadoes remain possible through tonight, mainly across
central and eastern portions of the Florida Peninsula and extreme
southeast Georgia.
THE EYE: Do not venture outside when the calm eye of the hurricane
passes over, as dangerous winds will return very quickly when the
eye moves away.
SURF: Swells generated by Irma are affecting the southeast coast of
the United States. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.

to remain a powerful hurricane while it moves through the Florida
Keys and near the west coast of Florida.
Hurricane-force winds extend outward up to 80 miles (130 km) from
the center and tropical-storm-force winds extend outward up to 220
miles (350 km). A wind gust to 89 mph (143 km/h) was recently

Cape Sable to Captiva...10 to 15 ft
Captiva to Ana Maria Island...6 to 10 ft
Card Sound Bridge through Cape Sable, including the Florida Keys...

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.
Northern coast of Cuba in the warning area...5 to 10 ft
WIND: Hurricane conditions are expected to continue within the
hurricane warning area along the north coast of Cuba through
this morning. Hurricane conditions are spreading across portions of
the Florida Keys and southern Florida. Winds affecting the upper
floors of high-rise buildings will be significantly stronger than
those near ground level. Tropical storm and hurricane conditions
are expected to spread northward across the remainder of the warning
areas through Monday. Tropical storm conditions are possible in the
watch area in the Northwestern Bahamas today.
RAINFALL: Irma is expected to produce the following rain
accumulations through Wednesday:
Western Cuba...Additional 3 to 6 inches, isolated 10 inches.
Western Bahamas...Additional 2 to 4 inches, isolated 6 inches.

In all areas this rainfall may cause life-threatening flash floods
and, in some areas, mudslides.
TORNADOES: Tornadoes are possible through tonight, mainly across
southern, central, and eastern portions of the Florida Peninsula.
THE EYE: Do not venture outside when the calm eye of the hurricane
passes over, as dangerous winds will return very quickly when the
eye moves away.
SURF: Swells generated by Irma are affecting the southeast coast of
the United States. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.
