expected somewhere within the warning area.

Interests elsewhere in the Dominican Republic and Haiti, as well as

monitor products issued by your local National Weather Service
forecast office. For storm information specific to your area outside
the United States, please monitor products issued by your national
meteorological service.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Irma was located
near latitude 19.4 North, longitude 66.8 West. Irma is moving toward
the west-northwest near 16 mph (26 km/h), and this general motion is
expected to continue for the next couple of days.  On the forecast
track, the extremely dangerous core of Irma will continue to pass
just north of Puerto Rico tonight, pass near or just north of the
coast of Hispaniola Thursday, and be near the Turks and Caicos and
southeastern Bahamas by Thursday evening.

Maximum sustained winds are near 185 mph (295 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 50 miles (85 km) from the
center and tropical-storm-force winds extend outward up to 185 miles
(295 km).

The estimated minimum central pressure is 916 mb (27.05 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  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
Northern coast of the Dominican Republic...3 to 5 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

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...

Northern coast of Puerto Rico...2 to 4 ft
Southern coast of Puerto Rico...1 to 3 ft

Water levels in the U.S. and British Virgin Islands will gradually
subside tonight and early Thursday.

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:  Tropical Storm and Hurricane conditions will continue to
spread westward over portions of Puerto Rico tonight.  Hurricane
conditions are expected to begin within the hurricane warning area
in the Dominican Republic and Haiti early Thursday, with tropical
storm conditions beginning later tonight.  Hurricane conditions are
expected to begin in the warning area in the southeastern Bahamas
and the Turks and Caicos Islands by late Thursday with tropical
storm conditions by early Thursday.  These conditions will spread
into the Central Bahamas by Thursday night or early Friday.

Hurricane and tropical storm conditions are possible within the
watch area in Cuba by Friday.  Tropical storm conditions are
expected to begin within the warning area in Cuba Thursday night.

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

Northern Leeward Islands...Additional 1 to 3 inches.  Storm total 8
to 12 inches, isolated 20 inches.
Northeast Puerto Rico and the British and U.S. Virgin Islands...6 to
12 inches, isolated 20 inches.  Southwest Puerto Rico...3 to 6
inches, isolated 10 inches.
The Southern Leeward Islands, and Saint Croix...2 to 4 inches.
Southeast Bahamas, Central Bahamas, and the Turks and Caicos...8 to
12 inches, isolated 20 inches.
Northern Dominican Republic and northern Haiti...4 to 10 inches,
isolated 15 inches.
Eastern and Central Cuba...4 to 10 inches, isolated 15 inches.
Southwest Haiti...1 to 4 inches.

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

SURF:  Swells generated by Irma will affect the northern Leeward
Islands, Puerto Rico, the Virgin Islands, the southeastern Bahamas,
the Turks and Caicos Islands, the northern coast of the Dominican
Republic, and portions of the southeast coast of the United States
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.

MY ANALYSIS THIS MORNING (NOT AN OFFICIAL FORECAST)

Here is a quick update of what I am seeing that may be hope for Florida.
As you well know I been sharing with you the HWFI, HWRF and the HMON model run and checking for trends and shifts in the model run because of the trough digging south and east.
Last night the surface map showed the high pressure ridge over northern Florida and the front stationary and draped almost horizontally. Then I notice the HWFI, HWRF and the HMON that were trending west-northwest now trending north over Florida. I also noticed other models off the the right and over the Bahamas. So I thought okay it does not look good for Florida but the other models are out over the Bahamas so NHC forecast track will adjust over night over Florida and if the HWFI and HWRF start shifting to the right like the others this mean the High pressure ridge is shifting east because the trough is also tracking south and east pushing on the high. So this morning Model HWFI shifted way out over the Bahamas and this caught my attention. So I went to the surface map and that confirmed that shift to the right of the models. There high pressure ridge has indeed shifted to the east because the trough continues to dip south and east. There is now an opening along the east coast for Irma to move into. Lets just hope I'm correct and the trough continues dipping south and east to keep this
However, folks this is not an OFFICIAL FORECAST SO PLEASE continue preparations and be hurricane ready!
