Models trending weaker and weaker. It'll likely be a strong TS/CAT 1 at peak. If it survives at all. Yesterday I thought there was a chance it may hit cat 2 but those odds are looking quite low now.

12z Euro sort of raises an eyebrow with a track about 75-100 miles further west and she would spend a good bit of time over the eastern GOM possibly allowing strengthening.

I think the EURO is too weak, but if you blend it all......ready for this? a landfall point near MIA looks possible at this point then riding northward through the spine of FL. Euro goes to the eastern gom..hahah


Watched your facebook video track last night, thought it was crazy... Funny how things change... Spot on per the 11am prediction... :D


LOL thank you! We shall see, but I think thats a good blend.

If you split the models and go in the middle, that would have the storm riding the spine all the way up through FLA. Since we do not know if it will be off shore east coast, or west coast if either and will it have time to get stronger still a little unknown at this point.

After looking at the current satellite loop I'm thinking the center fix earlier today was not that meaningful,especially since the center has raced north since then and is currently building convection. Looks to be returning to a position just a little south of this mornings track. We shall see.

Strange, ECM has Erika at 46kts at 60 hrs and weakens it to 35kts prior to landfall.

I think the ECM is picking up on stronger SW shear in the Gulf at that time.

My two cents? The LLC and MLC are trying to vertically stack -- with the LLC getting dragged N and a bit E of N, while the MLC and fresh convection is getting dragged N and W. IF that is right, and the centers can align and stay that way, Erika may begin strengthening soon.

Just the opinion of a semi-educated amateur. Listen to the experts, as always!

Are the GFS Ensemble members indicating faster forward motion, or higher (stronger) winds.

It weakens it from just north of Eastern Cuba to near Miami, I would have expected at least a slow strengthening over those VERY warm SST's!

Wouldn't that mean a shift back to the east?

Out of curiosity, does anyone recall if the UK and the NAV-GEM's 12Z runs were trending weaker or stronger than their respective 0Z & 6Z runs?
