Don’t think so it’s about same spot vs 18z, just a bit stronger. No phantom GOM storm so far, not sure what effect, if any, it will have.

Ridge overhead here, doesn’t seem to be digging down as much.

Imo the Trough is to far North to pick this up with a Canadian ridge building behind it. Probably going to stall.

Completely different ridge placement now.

Extremely different Synoptic patterns between the 00Z GFS/CMC from the 12Z Euro heading into next weekend and the following week. Active northern branch shortwaves which really weaken the W-Atlantic ridge, and result in a safe recurve rather than a potential stall-out in weak steering in the CMC/GFS solution. The EC also seems to have a more western placement of the high amplitude SW US ridge which results in a generally more amplified/less progressive pattern. I would say the odds (taking into account the ensembles) do favor the GFS/CMC more progressive pattern, let's hope it holds.

Can't say it is 100% a fish on this one... Bermuda gets smacked pretty good on this GFS run.

Extremely sharp recurve at that latitude during Aug/Sept.

Bermuda’s turn to get whacked by a GFS model cane!

There is a little shortwave that dives down off Long Island that is supposed to catch potential Danielle and push her out to sea (maybe clipping Newfoundland down the road). Now, I always say I'd rather be in the model crosshairs of a hurricane at 120hrs plus than be in the model crosshairs of a hurricane at under 120hrs. A couple of days ago the models were clobbering Florida with a major hurricane. Hopefully, the OTS scenario will verify but right now it is 50/50 I'd say between OTS and a stall off the SE Coast.

We might expect some more extreme swings in modeling out beyond 5 days due
to the relatively slow movement of 91L

Last 3 runs of GEFS shows no more than ~10% of members hitting FL with a TC from this.

Exactly, if 91L isn't quick enough it'll miss the trough-induced weakness and then all bets are off. By Wednesday or Thursday, we should have a better idea.

1. No phantom cane on 0Z GFS and yet it still recurves away from CONUS.

FWIW 00Z ICON continues with more of a stall setup near the Bahamas (it only runs to 180 hours) stronger ridge, weaker northern shortwave (which prevents an initial recurve). UKMET is a bit further south than the GFS/CMC but since it only goes out to 144 hour not sure how the pattern would evolve beyond that. Unfortunately we probably won't know for a few days, although the system will probably take that long to organize anyway.

00z GFS/EURO both agree with a very sharp recurve well E of Bahamas & CONUS with Bermuda in play.

GFS gave up the phantom GOM MH and for now EURO kinda caved to GFS which has called for recurve for a while.

Still some track bifurcation related to ridge strength/short term intensity.

Unfortunately I can’t not allowed to post on S2K. Wish I could sorry. :(


Thanks for the heads up though. That explains the long range forecast I saw on Accuweather. The 8th and 9th would not be fun in West Florida either.

There is an island in the middle of the Atlantic named Bermuda.
