Hanna went to 'Dunkin last minute, quickly getting its act together now!

Good thing this storm doesn't have another day or so over water. Hopefully will be on shore within a few hours. Nevertheless, very heavy rain over the next few days in that area. What is it with Texas storms?

Hanna is looking the best she has yet on visible in my opinion. Still about 4-6 hrs left over water... could get up to 90mph

AF307 is off to Hanna. It’s at ~90.7W right now, so it should be no more than an hour until it reaches the storm. I’m betting it’ll find an 80 kt/972 mbar Cat 1.

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.

Very impressive visible presentation. The year of the overperformers.

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Pretty amazing how rapidly this storm was able to get from a TD to an impressive cat 1 in a day. Still quite a ways to go in hurricane season. Hopefully we don’t see many more in the gulf this summer. The water temps where Hanna is are 89F

And to put this all in perspective, if Isaiah forms even on the later side of the model guidance it will be a full week before Irene formed in 2005

If this came into the east GoM as a TS, instead of a barely discernible wave, this would now be a major for sure.
What's coming down the road?

Feeder band NW of the CoC is breaking up as it crosses the coast.
This may be the peak for intensification.

Looking at radar, the western part of the eye is 12-14 miles from reaching Padre Island. It should begin moving onshore before 2 pm CDT. The eye appears to still be slightly contracting. I think recon could find a 90 mph hurricane if they make it in time.

Regardless of whatever strength Hanna ends up landfalling as, her presentation sure looks like something plucked right out of the WPAC
