At 700 AM CDT (1200 UTC), the center of Hurricane Milton was located

north of the Yucatan Peninsula today and approach the west coast of
the Florida Peninsula on Wednesday.  The hurricane is forecast to
make landfall in Florida Wednesday night.

Maximum sustained winds are near 145 mph (230 km/h) with higher
gusts.  Milton is an extremely dangerous category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  While fluctuations in
intensity are expected, Milton is forecast to remain an extremely
dangerous hurricane through landfall in Florida.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 105
miles (165 km).

HAZARDS AFFECTING LAND
----------------------
Key Messages for Milton can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC
and on the web at hurricanes.gov/text/MIATCDAT4.shtml

STORM SURGE:  A storm surge will raise water levels by as much as 4
to 6 feet above ground level along the northern coast of the
Yucatan Peninsula in areas of onshore winds.  Near the coast, the
surge will be accompanied by large and destructive waves.

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 could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...

Anclote River, FL to Englewood, FL...10-15 ft
Tampa Bay...10-15 ft
Englewood, FL to Bonita Beach, FL...6-10 ft
Charlotte Harbor...6-10 ft
Yankeetown, FL to Anclote River, FL...5-10 ft
Bonita Beach, FL to Chokoloskee, FL...4-7 ft
Suwannee River, FL to Yankeetown, FL...3-5 ft
Chokoloskee, FL to Flamingo, FL...3-5 ft
Volusia/Brevard County Line, FL to Altamaha Sound, GA...3-5 ft

The deepest water will occur along the immediate coast near and to
the south of the landfall location, where the surge will be
accompanied by large and dangerous 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.

inundation, please see the National Weather Service Peak Storm
Surge Graphic, available at
hurricanes.gov/graphics_at4.shtml?peakSurge.

RAINFALL: Rainfall amounts of 5 to 12 inches, with localized totals
up to 18 inches, are expected across central to northern portions of
the Florida Peninsula through Thursday.  This rainfall brings the
risk of life-threatening flash, urban and areal flooding along
with moderate to major river flooding.

Milton will also produce rainfall totals 2 to 4 inches across the
Florida Keys through Thursday. In addition, rainfall amounts of 2
to 4 inches with isolated totals around 6 inches are expected across
northern portions of the Yucatan Peninsula.

Hurricane Milton, please see the National Weather Service Storm
Total Rainfall Graphic, available at

WIND:  Hurricane conditions will continue in the warning area in
Mexico today.  Hurricane conditions are possible in the watch areas
in Mexico today, and tropical storm conditions are expected to
continue in tropical storm warning area today.

Hurricane conditions are expected in the warning area on the west
coast of Florida as early as Wednesday afternoon, with tropical
storm conditions beginning early Wednesday.  Hurricane conditions
are expected along the east coast of Florida in the warning areas on
Wednesday night, with tropical storm conditions possible beginning
late Wednesday afternoon.  Tropical storm conditions are expected 
in the tropical storm warning areas in Florida beginning early 
Wednesday and will spread northward through the day. Tropical storm 
conditions are possible within the watch area on the east coast of 
Florida by Wednesday night and along the Georgia and South Carolina 
coasts on Thursday.

TORNADOES: A few tornadoes are possible over central and southern
Florida beginning late tonight and continuing through Wednesday
night.

SURF:  Swells generated by Milton are expected to continue to
affect much of the Gulf Coast within the next day or two, and are
likely to cause life-threatening surf and rip current conditions.
