I want to know why we're quoting tweets from randos on Twitter


That's a great question. Usually it's harmless, maybe equivalent to someone posting here, HOWEVER if it's criticizing by assigning intent, like that tweet did, it violates S2K guidelines as if it was posted here. This is a reminder to everyone, please be aware of what you post. If I had a dollar for every rando who thought they were smarter than the NHC I'd be pretty wealthy. It's ok to disagree with the NHC but not then go on to make baseless accusations.

I’m surprised we got a borderline hurricane out of Alex. 60 kt and 984 mbar makes Alex ‘22 the strongest first named Atlantic storm since the previous Alex in 2016, which was also the strongest since the Alex before that in 2010.

This name list continues its streak of stronger-than-normal first storms.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Recon reports winds are down to about 45 kts now. I think the NHC will declare it ET in their next advisory.

The storm has gotta be extra tropical now. Only reason it still might be tropical is because of the displaced deep convection to its NorthEast.

I wouldn't be shocked to see this in the post-season report being extended as a tropical cyclone to maybe as early as a few hours before it made landfall on Florida. That is about the time that the center took over and most certainly by the time it was about to waterfall back into the Atlantic as surface obs were pretty convincing. Either way Florida got a 45 knot tropical like system! ;) Thank god for PTC reports that can give some warning to people.

I don't believe there were any sustained winds in Florida of 39 mph or higher. Center was not identifiable as it crossed Florida.

I’ve seen some suggest it may have briefly been a TS and the degenerated near the Yucatán after it first formed - need to see how good the LLC was then.

Either way this storm certainly threw me in a loop thinking it might have never become Alex initially, then again when it almost became a June hurricane.

Interesting note here was also Alex in 2004 reaching Cat 3 at a high latitude (and not to mention Andrew and Allen preceding in that name slot)

Both Allen and Andrew were August storms, back when the "A" storm used to form in August or even September. Ah, the good old days. Allen (1980) was the first hurricane I ever forecast, right out of college. I remember working 16 days straight.

Alex is a hurricane force low now.
