If you live in Florida anywhere near the Gulf Coast from Apalachicola to Ft. Myers, and especially anywhere within 20-30 miles of Tampa/St. Pete, it's time to start thinking about rushing preparations to completion or perhaps evacuating.
Unfortunately, it's game on for Hurricane Ian, as the storm is rapidly intensifying, with winds up to 100 mph (a 20 mph increase over 6 hours) and much more impressive circulation, deep convection, symmetry and outflow, all hallmarks of a rapidly intensifying system. Unfortunately, Ian is forecast to be up to 120 mph as it crosses the far west end of Cuba tomorrow morning and to reach up to 140 mph as it reaches the latitude of Key West on Wednesday morning (but it will be over 100 miles west of KW at that time, so impacts there should not be major, although 2-4' storm surge could lead to significant flooding).
The storm is forecast to weaken some (good for obvious reasons) and to slow down (bad, as it will extend the time of surge/winds/rain) as it then travels NNE towards Tampa, given predicted increases in SW shear from the approaching major front in the eastern US, but is still forecast to be at 115 mph as it just about makes landfall in the Tampa/St. Petersburg area Thursday morning (the forecast has it being about 20 miles off the coast of St. Pete Thursday morning) and the forecast then has it further weakening to about 85 mph as it makes landfall somewhere between Clearwater and Cedar Key Thursday evening.
Having said that, the cone of uncertainty still includes landfall potential anywhere from Ft. Myers to Apalachicola and impacts in that entire area will be significant, including well inland.
Storm surges of 5-10 feet area being predicted for the Tampa/St. Pete area (including all of the Tampa Bay) and 4-8' north of there to the Suwanee River and south of there to about Ft. Myers, as per the graphic below. This will be major to catastrophic in most of those locations. The NHC is even predicting 2-4' surges for NE FL and SE GA. Obviously, 115+ mph winds could bring major damage and even 85 mph winds can bring damage as the storm weakens some. In addition, widespread rainfall of 6-10" will be common throughout almost all of Florida (and locally more, especially near Tampa), as per the graphic below, which will lead to major flooding. And finally, storms like this always bring the threat of tornadoes, especially to the NE and E of the storm's center, which will include most of Florida.
Beyond Florida, the storm will slowly weaken to a TS in northern Florida, near Jacksonville, and then a tropical depression/remnant low near the Augusta GA area by Saturday afternoon, where the main threats will be flooding rains (4-6" possible) and possible tornadoes. Impacts for our area are not expected to be major, as rain from the remnant low by Sunday is the only threat - and we could use the rain - but the remnants may miss to our SE. Ian is not expected to reemerge into the Atlantic to regain TS status.
