DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the eye of Hurricane Milton was located
near latitude 21.9 North, longitude 90.4 West.  Milton is moving
toward the east near 10 mph (17 km/h).  This general motion is
expected through tonight followed by a turn toward the east-
northeast and northeast on Tuesday and Wednesday.  On the forecast
track, the center of Milton is forecast to move near or just north
of the Yucatan Peninsula tonight and Tuesday, then cross the eastern
Gulf of Mexico and approach the west coast of the Florida Peninsula
on Wednesday.
 
Hurricane Hunter aircraft indicate that the maximum sustained winds 
remain near 180 mph (285 km/h) with higher gusts.  Milton is a 
potentially catastrophic category 5 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 80
miles (130 km).
 
The minimum central pressure estimated from Hurricane Hunter 
aircraft observations is 897 mb (26.49 inches).
 
 
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
Flagler/Volusia County Line, FL to Altamaha Sound, GA...3-5 ft
Sebastian Inlet, FL to Flagler/Volusia County Line, FL...2-4 ft
Altamaha Sound, GA to Edisto Beach, SC...2-4 ft
Dry Tortugas...2-4 ft
St. Johns River...2-4 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.
 
For a complete depiction of areas at risk of storm surge
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 10 inches, with localized totals
up to 15 inches, are expected across portions of the Florida
Peninsula through Thursday. This rainfall brings the risk of
considerable flash, urban, and areal flooding, along with the
potential for moderate to major river flooding.
 
Milton will also produce rainfall totals 4 to 7 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
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero.
 
WIND:  Hurricane conditions are expected in the warning area in 
Mexico within a few hours, with tropical storm conditions currently 
occurring.  Hurricane conditions are possible in the watch areas in 
Mexico beginning tonight and Tuesday, and tropical storm conditions 
are expected in the tropical storm warning area beginning tonight.
 
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 
could begin along the east coast of Florida in the watch areas on 
Wednesday night, with tropical storm conditions possible beginning 
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. 
 
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.
Please consult products from your local weather office.
