Summary: Milton back up to 165 mph Cat 5 status with landfall now forecast to be further south than earlier today, i.e., in the Bradenton to Venice area (Sarasota being at the forecast track center) as a strong Cat 3 with ~125 mph winds around 12-2 am Thursday. After that, Milton is forecast to cross the FL peninsula, while weakening to a Cat 1 storm (~85 mph) upon exiting into the Atlantic, near Melbourne, which is also south of earlier forecasts. Substantial to catastrophic damage is expected from winds, surge and eventual inland flooding from torrential rains, as detailed below, with some isolated small tornadoes to boot. Mass evacuations are well underway in large parts of Central Florida.
Details: The 5 pm NHC advisory just came out and Milton has strengthened back up to 165 mph (cat 5) with a more symmetrical structure and clearer eye than earlier today and a larger eye and larger diameter wind field vs. yesterday when it was a Cat 5 with ~180 mph winds, but was much smaller; this is a bit of a surprise as the 11 am NHC advisory did not have Milton reaching Cat 5 status again - once again, this reflects the difficulty of making accurate intensity forecasts. Milton is, however, still forecast to encounter significant shear and some dry air entrainment tomorrow in the 12-24 hours before landfall, weakening the storm considerably to about 125 mph (strong cat 3) at landfall, but as I've said countless times, intensity forecasts are much less accurate than track forecasts, so people near the projected landfall need to be preparing for at least a Cat 4 storm (130+ mph), IMO.
Milton's track shifted another 10-15 miles southward vs. the 11 am NHC track, with the center of the track now predicted to hit the Sarasota area (was Bradenton); if this were to verify, the Tampa area would be spared some of the worst storm surge, being to the north of the track and on the weaker side of the storm, but we're still too far out to discount a Tampa landfall, as there are still models showing a Tampa or even a bit further north landfall (but most have landfall from Bradenton to Venice) since the forecast cone still runs from Tarpon Springs to Fort Myers (which includes the Tampa area), as track errors are still in the 40-50 mile range at 30-36 hours before landfall. Having said that, a direct hit on the Tampa/St. Pete area is certainly a bit less likely than it was yesterday. On the other hand, areas from Englewood to Ft. Myers now are at greater risk of landfall and catastrophic wind/surge damage. See the usual track map and a zoomed in version of the track map for just Florida.
After landfall, Milton is forecast to cross the FL peninsula, weakening to a Cat 2 storm about halfway across the peninsula (near Lake Wales, a good ~35 miles south of Orlando) and further weakening to a Cat 1 storm (~85 mph) upon exiting into the Atlantic, near Melbourne, which is also south of earlier forecasts with Daytona to Port St. Lucie still being in the track cone. Obviously, hurricane conditions will be very likely for a large swath of central Florida from the Gulf to the Atlantic, although they'll clearly be more severe along the Gulf and much less severe along the Atlantic.
Given significant southward track shift since yesterday, the surge forecast has been updated to expand the worst surge further southward with 8-12' of surge now forecast from Englewood to Bonita Beach (including Ft. Myers) and even 5-8' of surge now likely from Bonita Beach to Chokoloskee (including Naples/Marco Island). The surge forecast of 10-15' from the Anclote River to Englewood, including Tampa Bay hasn't changed, but realistically, with a track ~20 miles south of Tampa, that forecast will likely be decreased somewhat, although I'm sure the NHC doesn't want to do that until they're absolutely sure the storm won't hit Tampa. Anywhere that sees storm surges over 5-6' will likely see substantial to catastrophic damage (Tampa saw 7' of surge in Helene and that caused widespread major to catastrophic damage). Obviously, the wind damage will be major to catastrophic especially along/near the coast and even inland a ways, with widespread downed trees/power lines and associated power outages and some major structural damage, especially near the coast.
Lastly, the rainfall forecast continues to show widespread 8-12" amounts - and locally 12-16" amounts - are likely for much of central Florida near and maybe 50-75 miles north of the track (due to interactions with the approaching front; this is unusual, as typically more rain falls south of a hurricane's track) with 4-8" well north of the track and just to the south of the track, as per the graphic below. There is clearly the risk of catastrophic inland flooding in areas that get more than 8" of rain (and especially up to 16"), while major flooding will be widespread throughout areas getting over 6" of rain. And a reminder that we're likely to see numerous small tornadoes, along and south of the storm's track across the state.
