Terrifying right now in Fort Walton Beach. I have never seen so many rotating cells coming onshore so quickly. Warning after warning with strong couplets on velocity scans.

I was think about 5 central myself. Which is about one hour. The center is now 5 to 6 miles out from the beach.

Almost too fast to react...I'm in Shalimar on the bay.

[Chemmers]

I wonder with it moving so slow, that the South side of the eye will be cat 3 when it come ashore maybe?

[wx98]

Landfall will be soon at Gulf Shores. About 4 miles out now going by radar.

Recon through 4:10am CDT:

[Dean4Storms]

Just had a weak tornado go by complete with power flashes just to my west.

[FLpanhandle91]

Just had a weak tornado go by complete with power flashes just to my west.

There at least 5 more rotating cells coming your way within the next 20 minutes man.

[wx98]

Recon coming for another pass but NHC isn’t convinced of these elevated FL winds with such comparatively lackluster SFMR data.

[Blackwaterjoe22]

Surge now starting to get in house here on Blackwater Bay.
Gonna be a long few hours upcoming

That onshore wind is probably gonna continue for several more hours. I hope you stay safe!

Splash.

That would support a Category 3.
I’ve been waiting for them to start dropping and showing what we’ve been trying to say about those FL winds making it down to the surface!

Yeah, but is a spot wind. Though if you add it to the data from the flight level winds then it would be a strong case.
