interaction with the Yucatan is affecting it and it should not strengthen until the system gets more out in the Gulf..

Personally I think the reason is because people are just burned out on this hurricane season and want it to be over with already,

I think it's because people were expecting a Wilma-level storm yesterday and stopped watching once it collapsed, out of a strange form of disappointment.


I think many people are Model and track fatigued. The storms this year, have seemed so unpredictable! And there has been so many. I know for me personally, until it gets closer, I feel like I cant really count on the predictions. I really hate saying that, and I know overall accuracy has gotten so much better. But that is just how it "Feels"??? :cry:

I think it is about to start ramping up, as soon as it gets a little further out into the GoM it is a go for bombing I'm afraid.

I guess that makes sense. When I use to chase Tornados in Eastern Colorado, I would often go home feeling down if I didn't see a funnel cloud touch down. I didn't want to see anyone's homes get wrecked of course, but it as all about the thrill of the hunt and visuals. That's probably what's going on here.

We will see what the NHC has to say in the next half hour, the next advisory will be telling, but the one at 10 pm (Central) tonight will be more telling, and that is the one I'm be actually looking at to determine what exactly I should be expecting.

Coldest cloud tops pretty circular on IR now with a warm-core feature in the middle.

ADT calling a uniform CDO.

Delta grabbed our attention when it apparently tried to become Wilma 2.0, but when the spirit of 2020 decided that was somehow too much and shot it down via unexpected mid-level shear, the hype pretty much died.

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.

Looks like Delta is slowly getting better organized this afternoon. Further intensification looks very likely as upper level conditions looks very favorable the next day with ridging aloft. Delta should transverse SST that are quite warm. Delta should get close to Cat-4 intensity IMO. Lets hope shear increases and cooler shelf waters knock Delta down a couple of Cats prior to landfall. Surge is going to be quite high in the RFQ at landfall....MGC

Big increase in instability across a large portion of the GoM since this morning.
CAPE up to 5000.
6000 is usually when the big RI fuel kicks in

Winds are much higher on the latest recon pass. It now looks like a solid Cat 1 compared to earlier when it was barely hanging on.

If this was ever lower than a Cat 1 than this is the most Cat 4 looking-Cat 1 I've ever seen.

You're not wrong. Especially in the BR/Hammond area which I believe we share, basically every hurricane that's struck the northern gulf has, at one point or another, had a forecast track pointed at our area . . . sometimes two at the same time, criss-crossed . . . only to see it actually hit the other side of the state, or even another state, entirely. It's like the BR/NO area is the "default target".

Even as Delta models trend more westward (itself 2020's trend), the accuracy issues keep me up at night since, eventually, one's luck runs out.

Modest pressure falls now resuming with a bump in the winds as well this pass.

Should have until Friday morning to deepen.
