GFS is WAYY south taking it into NC as a cat 5. The thinking is it's still too far north. Should end up in the Leeward islands in ~5 days.

Watch the SW turn, climo for storms that make that turn is a bit concerning. Last two Euro EPS runs:

Not necessarily there's been plenty of storms that have survived Cuba fine depending on their strength. Plus the gulf is a powder keg at the moment so once it gets in it would be able to regain its strength quickly.

We are talking beyond D10 for something to get in the Gulf. The operational models show little skill at that point. The ensembles are somewhat useful but are still prone to totally flipping on things at that range. The Euro EPS has more members and is more dispersive than the GEFS, so on any random run it is more likely to get members in the Gulf in the long range.

The 00z super ensemble mean is still east of the US. However, the EPS trend is concerning as it lights up the eastern Gulf.

Wrt location/intensity where #Irma's unusual WSW movement is occurring, it bears a lot of similarities to the 1947 Ft. Lauderdale Hurricane

These tweets are just unnecessary hype. Taking a southwesterly turn 3000 miles from the US doesn't mean a damn thing about what it will do in a week.

For the most part. It is showing a northward motion bias in the short range. However, pretty much all models are in the short term with this system. Big key, how much lat does it gain in the next 24hrs before bending back SW.

Has to be scary as hell to be stuck in the Lesser Antilles during one of these storms.
