HMON puts out some winds and a low. HWRF ignores.

Congratulations!  Never too early to get them started on weather.

Platform is struggling today.

MJO sliding onto our side for some models.

Gulf disturbance up to 60%.

GFS and EPS lining up again on an eastern threat - whether it's tropical is debatable as it's probably similar to what we are seeing offshore today. They both rotate this one around an upper low and bring on shore.

I'll be kind of shocked if there's not a major late season hurricane. At least one. 

 

The heat had to reconcile and these storms are the mechanism. The sal and other factors prevented the epic season that was predicted so logic dictated the late season will be dangerous as a mofo.

ECMWF AI model is trending towards an active second week of September in the Gulf ... I wouldn't bet against it

Latest version of this model valid at the same time that intensifies as landfall approaches later in the model run

I think it's safe to chalk this up as a win for long range day 10+ AI models and tropical threats

Late season? We're in the heart of the season now and systems are simmerin'

Well peak season is late season when it comes to hurricanes but you know what I mean

Opening up a thread on PTC 6/91L as it seems pretty much a sure thing and its only 3 days from landfall.  Must be waiting for more organization.  Update out soon.

Invest 92L (60%) is currently near 40W.  No invest for the one behind it which is at 70%

If the one behind it has a better chance, why did they not create an invest for it?

This hashed area has some interesting activities.  GFS is bullish, the AIFS has development too.  Not sure if its not tropical/sub/semi/hemi/extra/post but GFS has it hitting NC

But the Euro EPS and op don't have it.

Euro op has a low further out in time.

The ICON has this offshore for the run and then deepening and sitting just offshore of OBX

 UKIE is weak into GA and CMC has nothing.
