Re: ATL: INVEST 91L - Models
That member with a sub-930 in the warmest waters of the Caribbean

I guess 2022 got angry we were making fun of it after a dead August... this season could be more impactful than 2021 at this point, even if 2021 exhausted the name list.

This is like a certain football game; the first half does not matter compared to the second half because anything can change!

Re: ATL: INVEST 91L - Models
The 12Z EPS, though its mean is not nearly as active as the 12Z GEFS, did have a slight increase vs the 0Z EPS with several members having hurricanes vs none that I could see on the 0Z. More than likely, the Euro suite is underdone on the chances of this ending up as a strong TC by the W Caribbean although the GEFS could easily be overdone in the E Caribbean especially.

Re: ATL: INVEST 91L - Models
There’s a pretty significant timing difference between the CMC/ICON and GEFS. On the former, 91L reaches the Lesser Antilles in about 72 hours (10/5) and hits Central America by 180 hours (10/10). The GEFS takes 24-30 hours longer to reach both points (LAs on 10/6, CA on 10/11 or early 10/12). However, all modes take about 5 days for 91L to travel from the Lesser Antilles to Central America (or its longitude).

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.

Re: ATL: INVEST 91L - Models
Still no development on the 18z GFS. The culprit appears to be the ULL currently sitting to the NNE of 91L. Right now it’s helping ventilate the disturbance, but once 91L reaches the Lesser Antilles, the ULL will be imparting hostile flow into it from the north.

0z CMC, slightly further north into Honduras with same intensity as 12z:

0z operational GFS still doesn't develop it.

Re: ATL: INVEST 91L - Models
First HMON run has it getting down to 991mb pretty quickly before weakening as it reaches the islands.

Re: ATL: INVEST 91L - Models
0z gefs has a stronger signal than the 18z did, but looks bound for Central America like the other models showing development
