Irma Update Labor Day Morning

Visible image at top shows Irma over the Atlantic at 8:45 am EST this morning. Storm was at a high  level Cat. 3 hurricane, with winds at 120 mph. Just above is NHC current track forecast. There is amazingly little spread in the model forecasts and NHC forecasts have shifted the track considerably to south during last several forecast cycles.

Surface forecasts from the ECMWF (just below) and GFS (bottom) are very similar out at seven days (8:00 pm EST next Sunday).
