DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM EDT (0300 UTC), the center of Hurricane Irma was located
by NOAA Doppler radar near latitude 27.5 North, longitude 81.9 West.
Irma is moving toward the north near 14 mph (22 km/h).  A turn
toward the north-northwest and then northwest at a faster forward
speed is expected during the next day or so.  On the forecast track,
the center of Irma will continue to move over the western Florida
peninsula through Monday morning and then into the southeastern
United States late Monday and Tuesday.

Doppler radar data indicate that maximum sustained winds have
decreased to near 100 mph (155 km/h) with higher gusts.  Additional
weakening is forecast, and Irma is expected to become a tropical
storm over far northern Florida or southern Georgia on Monday.

Irma has a very large wind field. Hurricane-force winds extend
outward up to 80 miles (130 km) from the center, and tropical-storm-
force winds extend outward up to 415 miles (665 km).

The estimated minimum central pressure is 952 mb (28.12 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...4 to 6 ft
Captiva to Anna Maria Island...3 to 5 ft
North Miami Beach to Cape Sable, including the Florida Keys...3 to 5
ft
Anna Maria Island to Clearwater Beach, including Tampa Bay...2 to 4
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

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
central Florida peninsula.  Winds affecting the upper floors of
high-rise buildings will be significantly stronger than those near
ground level.  Tropical storm conditions will continue across
portions of southern Florida and the Florida Keys through Monday
morning.  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 overnight.

RAINFALL:  Irma is expected to produce the following rain
accumulations through Wednesday:

Western Bahamas...Additional 2 to 4 inches.

The Florida Keys...Additional 1 inch possible 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:  A few tornadoes are possible across northeast Florida
and southeast portions of Georgia and South Carolina through Monday
night.

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.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 PM EDT (2100 UTC), the center of Hurricane Irma was located
near latitude 26.2 North, longitude 81.8 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 are near 110 mph (175 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).  A mesonet site at Naples Municipal Airport
recently reported a sustained wind of 88 mph (142 km/h) with a gust
to 135 mph (217 km/h) while in the northern eyewall of Irma.

The minimum central pressure reported by an Air Force Hurricane
Hunter aircraft is 938 mb (27.70 inches).  A pressure of 937 mb
(27.67 inches) was measured by a storm spotter on Marco Island while
in Irma's eye.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 AM EDT (0900 UTC), the center of Hurricane Irma was located
near latitude 24.1 North, longitude 81.5 West. Irma is moving toward
the northwest near 8 mph (13 km/h).  A turn toward the north-
northwest and an increase in forward speed are expected later today,
with that motion continuing through Monday.  On the forecast track,
the eye of Irma should move over the Lower Florida Keys in the next
few hours, then move near or over the southwestern coast of the
Florida Peninsula later today through tonight.  Irma should then
move inland over the Florida panhandle and southwestern Georgia
Monday afternoon.

Maximum sustained winds are near 130 mph (215 km/h) with higher
gusts.  Irma is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  While weakening is forecast, Irma is
expected to remain a powerful hurricane as it moves through the
Florida Keys and 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).  The National Ocean Service station at Vaca Key
Florida recently reported sustained winds of 48 mph (78 km/h) and a
gust of 78 mph (126 km/h).  A private anemometer at Alligator Reef
Light, Florida recently reported a wind gust of 88 mph (141 km/h).

The latest minimum central pressure reported by an Air Force
Reserve Hurricane Hunter aircraft is 928 mb (27.41 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
Ana 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...2 to 4 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.

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 should spread northward over the remainder of
the Keys and the southern Florida peninsula during the next several
hours.  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.
The Florida Keys...15 to 20 inches, isolated 25 inches.
The southern Florida peninsula...10 to 15 inches, isolated 20

The remainder of the Florida peninsula and southeast Georgia...8 to
12 inches, isolated 16 inches.
The rest of Georgia, eastern Florida Panhandle, southern and western
South Carolina, and western North Carolina...3 to 6 inches, isolated
10 inches.
Eastern Alabama and southern Tennessee...2 to 5 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.

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 36 hours in the indicated locations. For a
depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at
hurricanes.gov.  This is a life-threatening situation.  Persons
located within these areas should take all necessary actions to
protect life and property from rising water and the potential for
other dangerous conditions.  Promptly follow evacuation and other
instructions from local officials.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area.  Preparations to protect life and
property should be rushed to completion.

A Hurricane Watch means that hurricane conditions are possible
within the watch area.  A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM EDT (0300 UTC), the eye of Hurricane Irma was located
near latitude 23.5 North, longitude 81.0 West. Irma is moving
slowly northwestward away from the north coast of Cuba near 6 mph
(9 km/h).  A turn toward the north-northwest with an increase in
forward speed is expected through late Monday.  On the forecast
track, the center of Irma is expected to cross the Lower Florida
Keys Sunday morning and then move near or along the west coast of
Florida Sunday afternoon through Monday morning.  Irma should then
move inland over the Florida panhandle and southwestern Georgia
Monday afternoon.

Maximum sustained winds are near 120 mph (195 km/h) with higher
gusts.  Irma is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Irma is forecast to restrengthen a little
while it moves through the Straits of Florida and remain a powerful
hurricane as it approaches the Florida Keys and the west coast of
Florida.

Hurricane-force winds extend outward up to 70 miles (110 km) from
the center, and tropical-storm-force winds extend outward up to 205
miles (335 km).

The estimated minimum central pressure is 933 mb (27.55 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
Ana 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...2 to 4 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.

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.

Northwestern Bahamas...3 to 6 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 along the north coast of Cuba through
tonight. Hurricane conditions are expected in portions of the
northwestern Bahamas tonight, and in portions of the Florida
peninsula and the Florida Keys beginning Sunday morning.  Tropical
storm and hurricane conditions are expected to spread northward
across the remainder of the warning areas through Monday.

RAINFALL:  Irma is expected to produce the following rain
accumulations through Wednesday:

Northern Cuba...10 to 15 inches, isolated 20 inches.
Southern Cuba...5 to 10 inches, isolated 15 inches.
Western Bahamas...3 to 6 inches, isolated 10 inches.
The Florida Keys...10 to 20 inches, isolated 25 inches.
The Florida peninsula and southeast Georgia...8 to 15 inches,
isolated 20 inches.
The eastern Florida Panhandle and southern South Carolina...4 to 8
inches, isolated 10 inches.
Rest of eastern Georgia, western South Carolina, and western North
Carolina...4 to 8 inches.
Western Georgia, eastern and northern Alabama, and southern
Tennessee...2 to 5 inches.

In all areas this rainfall may cause life-threatening flash floods
and, in some areas, mudslides.

TORNADOES:  A few tornadoes are possible through Sunday night,
mainly across southern, central, and eastern portions of the Florida
peninsula.

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.
