DISCUSSION AND OUTLOOK
At 500 AM EDT (0900 UTC), the center of Hurricane Ian was located
near latitude 22.3 North, longitude 83.7 West. Ian is moving toward
the north near 12 mph (19 km/h), and this motion is expected to
continue today. A turn toward the north-northeast with a reduction
in forward speed is forecast tonight and Wednesday. On the
forecast track, the center of Ian is expected to move over western
Cuba during the next few hours. Ian will then emerge over the
southeastern Gulf of Mexico later this morning, pass west of the
Florida Keys later today, and approach the west coast of Florida
within the hurricane warning area on Wednesday and Wednesday night.
Maximum sustained winds are near 125 mph (205 km/h) with higher
gusts. Ian is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Little change in strength is expected while
Ian moves over Cuba. Strengthening is expected later this
morning after Ian emerges over the southeastern Gulf of Mexico.
Ian is forecast to approach the west coast of Florida has a major
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
The estimated minimum central pressure is 952 mb (28.12 inches).
HAZARDS AFFECTING LAND
Key messages for Ian 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: 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...
* Anclote River to Middle of Longboat Key, FL including Tampa
* Suwannee River to Anclote River...5-8 ft
* Middle of Longboat Key, FL to Englewood, FL...5-8 ft
* Englewood, FL to Bonita Beach, FL including Charlotte Harbor...
* Bonita Beach, FL to East Cape Sable, FL...3-5 ft
* Flagler/Volusia County Line, FL to Altamaha Sound including
St. Johns River...2-4 ft
* East Cape Sable, FL to Card Sound Bridge, FL including Florida
* Aucilla River to Suwannee River...2-4 ft
* Florida Keys including the Dry Tortugas...2-4 ft
* Indian Pass, FL to Aucilla 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

above normal tide levels along the coast of western Cuba in areas of
onshore winds in the hurricane warning area early today.
