This 100%. A quicker forming storm will get more north before the Yucatán, but a stronger storm in the epac will prevent that from happening due to resultant shear.

The fact that the GFS is starting to weaken the TUTT is concerning to me and not what you wanna see going into the most active part of the season.

Hey sorry,

It’s called a Tropical Upper Tropospheric Trough which essentially shears and sometimes helps recurve any tropical system coming from Africa or any for that matter.

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.

I’m getting a bad feeling about that potential system. It’s also forming around the same time Irma did in 2017, and like Irma, it’ll be heading west after a TUTT breaks down.

Euro wants to break down the ridge just enough to hit Texas and scrape along the coast till going inland around Corpus Christi. The problem is that it heads north and also hits Houston.

Still opportunity and even likelihood of it changing again, but it doesn't feel good seeing it. That ridge, as it was with Grace will be the key to this system.

Looks like that wall at 60W isn't going anywhere for now. Massive recurve signal on EPS with TUTT very much in place.

I know it's very far away, but I don't like this one. It's giving me Irma/Ivan vibes. With the exception of perhaps Teddy (which quickly went north after strengthening) we haven't really had a true lower MDR cruiser last year, but based on the runs I think there could possible be one this year.

Which is the right one? The above about Euro or what you said later?

It actually goes inland at Matagorda Bay.

I'm looking at the Euro but I don't see that.

At 300 hrs out that seems like it would change.

Well this is what is concerning. The 18Z GFS breaks down the ridge, but then reinforces it. If that doesn't happen, the Euro solution would be correct.

It looks like the GFS and Euro are going to be at war against each other over the next week. Who knows which one is going to be closer to being right.
