Irene and the models (For New England) and NOT a forecast...

This is a GFS model run comparison for Hurricane Irene and impacts in New England. These are not official forecasts, but for use to see trends and possible impacts with each model run. 

the 2AM 8/23 GFS brings Irene to the MA coast with the eye over Martha's Vineyard/New Bedford then over Provincetown.  The model runs have been consistent, wobbling between Cape Cod and Long Island for this coming Sunday into Monday. 964mb


The 2PM GFS (8/22) model has Irene, as a hurricane over New York City, what may be an eye or calm center is over Bridgeport, Ct at 11 AM on Monday. The strongest winds are on the right front quadrant of the storm, which could bring a significant storm surge into RI, Buzzards Bay and Narraganset Bay, MA.   Of interest with this track is that the storm hugs the entire Atlantic coastline, bringing hurricane conditions all the way into New England. (Note, the red line is from the previous forecast model run)

The 8 AM GFS (8/22) model had Irene missing the Carolinas and therefore not interacting with land maintaining a stronger hurricane over Buzzards Bay in MA as a 965mb hurricane, which would be more destructive for Nantucket and Cape Cod.  The red line indicates this models track.

The 2AM GFS (8/22)model had Irene, (after a Carolina strike), moving up the coast and being a hurricane just south of New York City at 2 AM on Monday August 29.  A 976mb hurricane at that
