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.

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 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.

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: 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.
