Models overnight and this morning have shifted slightly east.

The 6z GFS is very similar to the earlier run, but is slightly closer to the west coast of Florida, and has an interesting track back over the Atlantic from the Carolinas.

The 0Z Euro model moved eastward, and the CMC moved westward, so the alignment of the models is a bit better. It takes it over westward cuba and landfall is near Pensacola, FL. Wednesday night/Thursday.

6Z HWRF takes it in over Miami monday night, and it winds up over Tampa on Tuesday evening,

Still the initialization and structure of Isaac is poor, so changes may still occur, and adjustments both west and east will likely occur. Tomorrow hopefully should start to clear some of it up.

The large size of Isaac means it is likely to cause quite a bit of storm surge issues if it enters the Gulf and rakes along the west coast of Florida.

GFDL has landfall between somewhere Ft. Lauderdale and West Palm Beach early Monday.
