Re: ATL: IRMA - Models
Last one on this topic. You can see how chaotic everything becomes after about 6 days over North America. A lot can and will change when it comes to any potential US threat in 10 days or so.

Re: ATL: IRMA - Models
I'm surprised to read the MET(fox) saying this will probably be out to sea. While I also believe a recurve is highly probable, I also know that a a storm recurving can still take this into the NorthEast corner of the US.

Re: ATL: IRMA - Models
HWRF has shifted real westwards compared to yesterday and is on the southern end of the suite, it actually does hit the Leeward Islands as a powerful hurricane around 945mbs.
GFS ensembles shifting westwards, apart from the ECM most models have shifted westwards, and the ECM was probably too far west to start with. Starting to sniff a consensus at least out to 168hrs, though still huge spread after that point.
Generally three camps, one is a NE/OTS, another goes towards Carolinas and maybe up the coast, the final group keep headng towards Florida.
So ironic that the moment the ECM shifts northwards, the rest of the suite decide to shift back westwards! Wonder what the 12z ECM will do?!

In the possibly black humor department, the area with Irma in the later frames has a very cheery-looking smiley face in a couple of frames.

I wonder if that's a good thing in terms of the ridge backing off as it makes its way north.
