DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the center of Hurricane Milton was located
near latitude 23.0 North, longitude 86.9 West. Milton is moving
toward the east-northeast near 10 mph (17 km/h). A northeastward
motion with some increase in forward speed is expected tonight
through early Thursday. A turn toward the east-northeast and east
is expected on Thursday and Friday. On the forecast track, the
center of Milton will move across the eastern Gulf of Mexico tonight
and Wednesday, make landfall along the west-central coast of Florida
Wednesday night, and move off the east coast of Florida over the
Atlantic Ocean on Thursday.
Reports from Air Force and NOAA Hurricane hunter aircraft indicate
that the maximum sustained winds are near 165 mph (270 km/h) with
higher gusts. Milton is a category 5 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Fluctuations in intensity are
likely while Milton moves across the eastern Gulf of Mexico, but
Milton is expected to be a dangerous major hurricane when it
reaches the west-central coast of Florida Wednesday night.
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 140
miles (220 km).
The minimum central pressure estimated from Hurricane Hunter
aircraft observations is 902 mb (26.64 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 2
to 4 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...8-12 ft
Charlotte Harbor...8-12 ft
Chassahowitzka, FL to Anclote River, FL...5-10 ft
Bonita Beach, FL to Chokoloskee, FL...5-8 ft
Chokoloskee, FL to Flamingo, FL...3-5 ft
Yankeetown, FL to Chassahowitzka, FL...3-5 ft
Sebastian Inlet, FL to Altamaha Sound, GA...3-5 ft
Altamaha Sound, GA to Edisto Beach, SC...2-4 ft
Suwannee River, FL to Yankeetown, FL...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.

inundation, please see the National Weather Service Peak Storm
Surge Graphic, available at
hurricanes.gov/graphics_at4.shtml?peakSurge.
RAINFALL: Rainfall amounts of 6 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 catastrophic and life-threatening flash and urban flooding,
along with moderate to major river flooding.
Additional rainfall amounts of 2 to 4 inches, with isolated totals
around 6 inches, are expected across northern portions of the
Yucatan Peninsula.
For a complete depiction of forecast rainfall associated with
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: Tropical storm conditions will continue in portions of the
warning area in Mexico this evening.
Hurricane conditions are expected in the hurricane warning area
across Florida beginning late Wednesday through early Thursday and
are possible in the hurricane watch area on Thursday. Tropical storm
conditions are expected to begin in the warning area on the west
coast of Florida around midday Wednesday, spreading across the
peninsula and reaching the east coast Wednesday evening. Tropical
storm conditions are expected to begin in the warning area on the
east coast of Florida late Wednesday.
Tropical storm conditions are expected in the extreme northwestern
Bahamas on Thursday.
Tropical storm conditions are possible within the watch area
on 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 early Thursday
morning.
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.
