I believe this is going to be the start of the CV season. First week of Sept.

Worth noting the Euro shows four potential systems (including one system that clearly is) by 168h. 168h ago the Euro showed absolutely nothing on today's date.

The Hurricane Stock Market has begun! Pre-market had some decent returns.

The GFS puts a Cat 2 hurricane into the Louisiana/Mississippi border on September 5th, 16 days out. That's after it scrapes the Louisiana coast.

Probably a good post at this point, although I believe that the threat will be more likely the northwestern Gulf next time.

0z seems to significantly weaken the potential system around the beginning of September from previous runs. Likely will go back and forth on intensity but it’s almost likely (my opinion) that we shall see something in the GoM around September 3rd. Looks to come from the wave that comes off the African Coast later today.

Worth noting that none of the GFS, GEM, or Euro had any tropical storms in the Atlantic basin today if you go out five days or more. We're probably in for a lull for a few days but there are several areas of vorticity beyond the 4-5 day mark--something that wasn't even present in 120+ hour runs for today.

The track of that early September storm the GFS has been showing in the past few runs is odd. Forms in the Caribbean and tracks north across Cuba then a ridge of high pressure builds to the east forcing it to track WNW towards Louisiana. Right now the details of this potential storm are not important as these runs of the operational GFS have a close to 0 percent chance of verifying this far out, but we can take away from this is that there is a signal for some sort of development in the Carribean in the first days of September with no telling where it will go from there.

Things about to go into over drive come first week of September. Long range EPS now showing some big hurricanes nearing the northern Islands. With the CCKW overhead this could be a big one potentially.

The GEFS looks to have woken up with WCAR/BOC/WGOM development which aligns with the CMC/GEPS/EPS.I don’t buy the GFS Florida storm in fantasy land which looks like more of an October track not to mention an outlier.

GEFS Ensemble has been very consistent on this idea as well as some ECENS ensemble coming on board on some runs as well. I would prefer following ensemble data as it provides a more broad picture instead of just one model run.
