Faster movemnt means less time for the break in the ridge to occur, so it's shifting west, I think that's why the UK and Euro are further west than the GFS ones. Ultimately it's going to be razor close, or it shifts way further west than anticipated, the NHC's discussion for Irma this morning describes the model situation pretty well, and I think the official track is pretty good.
Recon is finding lower pressures again (919) which is a bit surprising, Hispaniola may have less of an affect than I thought it would.
