HWRF running. Looks like it might clip PR.

EDIT: Nope it misses to the south. Gets to 990mb before heading into DR

The 00Z EPS is much weaker and a bit faster than yesterday’s 12Z suite. Many fewer members show short-term (pre-Gulf) development as well.

Regardless if I was in the keys I would be preparing for a possible Cat1

Yes, err on the side of a stronger ridge rather than weaker in these situations, the modeling typically underplays the strength of the ridges even after recon does its thing.

06z HWRF 66 hours... Landfall PR, skims N coast Hispaniola... At 66 hours @.5 N of 00z and 7 mb's lower... Making the approach towards SFL, may be the strongest run so far??

The reason why the global models have and most likely continue to trend stronger with future Fred is because not only they have been trending it will track just offshore of the northern Cuban coast it will encounter a much less hostile environment in the eastern GOM, the TUTT/ULL that models were originally showing is now no were to be found this weekend near FL.

What about the shear in the Bahamas pre-Florida? Wouldn’t the TUTT still prevent “future Fred” from intensifying prior to reaching the eastern Gulf of Mexico?

06z HWRF's run will probably end much stronger than previous runs.

Westerly shear associated with the ULL still seems quite strong in the Bahamas as of day three (72h). I wouldn’t expect much deepening prior to the eastern GoM.

The 06z HWRF is ridiculous. No way that intensity is going to pan out.

It will not have the best UL conditions like it will have in the SE GOM but it will not be as hostile as earlier thought.
The models keep trending west away with the TUTT like feature ahead of Future Fred.

06z HWRF 90 Hours... 88 mph and has SFL in site... A little slower and north of previous runs... Missing/skimming Hispaniola allowed the HWRF to explode...
