STORM SURGE: The combination of 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...

* Middle of Longboat Key to Bonita Beach, including Charlotte
Harbor...8-12 ft
* Bonita Beach to Chokoloskee...6-10 ft
* Anclote River to Middle of Longboat Key, including
Tampa Bay...4-6 ft
* Chokoloskee to East Cape Sable...4-7 ft
* Suwannee River to Anclote River...3-5 ft
* Lower Keys from Key West to Big Pine Key, including the
Dry Tortugas...3-5 ft
* Flagler/Volusia County Line to Savannah River including St. Johns
River...3-5 ft
* St. Johns River south of Julington...2-4 ft
* Savannah River to South Santee River...2-4 ft
* East Cape Sable to Card Sound Bridge...2-4 ft
* Florida Keys east of Big Pine Key...2-4 ft
* Patrick Air Force Base to Flagler/Volusia County Line...1-3 ft
* Indian Pass to Suwanee River...1-3 ft

The deepest water will occur along the immediate coast near and to
the right of the center, where the surge will be accompanied by
large 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: Catastrophic wind damage is likely where the core of Ian
moves onshore. Hurricane conditions will begin along the west
coast of Florida within the Hurricane Warning area later this
morning, with tropical storm conditions beginning before daybreak.

Tropical storm conditions are occurring in the warning area in the
Florida Keys, and will continue this morning. Tropical storm
conditions are expected in the warning area on the east coast of
Florida beginning today, and should spread up the Georgia and
South Carolina coasts tonight and Thursday. Tropical storm
conditions are expected within the warning area in Cuba for the
next few hours.

RAINFALL: Ian is expected to produce the following storm total
rainfall:

* Florida Keys and South Florida: 6 to 8 inches, with local maxima
up to 12 inches.
* Central and Northeast Florida: 12 to 18 inches, with local
maxima up to 24 inches.
* Eastern Georgia and Coastal South Carolina: 4 to 8 inches, with
local maxima of 12 inches.

Widespread, life-threatening catastrophic flash, urban, and river
flooding is expected across central Florida. Widespread
considerable flash, urban, and river flooding is expected across
portions of southern Florida through Wednesday, and northeast
Florida, southeastern Georgia, and coastal South Carolina later this
week through the weekend. Limited flash, urban, and river flooding
is possible over portions of the Southeast and southern Mid-Atlantic
later this week through the weekend.

TORNADOES: Tornadoes are possible today and tonight across central
and south Florida.

SURF: Swells generated by Ian are affecting the northern coast
of Cuba, the northeastern coast of the Yucatan peninsula, the
Florida Keys, and the Gulf coast of Florida. These swells will
spread westward along portions of the north-central Gulf
coast during the next day or so. Swells will increase along the
east coast of Florida, Georgia, and South Carolina tonight and
Thursday. These swells are likely to cause life-threatening surf
and rip current conditions. Please consult products from your local
weather office.
