    From the National Hurricane Center.

    BASED ON AIRCRAFT AND SATELLITE FIXES…THE INITIAL MOTION ESTIMATE REMAINS 285/13.  EARL WILL GRADUALLY TURN TOWARD THE NORTHWEST IN THE NEXT DAY OR SO AS IT MOVES AROUND THE SOUTHWESTERN EDGE OF THE SUBTROPICAL RIDGE CENTERED ALONG 25N.  THE TRACK MODEL GUIDANCE IS IN GOOD AGREEMENT ON THIS SCENARIO AND THE OFFICIAL FORECAST IS NEAR THE MIDDLE OF THE TIGHTLY CLUSTERED GUIDANCE ENVELOPE THROUGH 24 HOURS.  AFTER THAT TIME MOST OF THE TRACK GUIDANCE HAS SHIFTED FARTHER WEST…ESPECIALLY AT 72 HOURS AND BEYOND…AS EARL TURNS NORTH-NORTHWESTWARD AND INTERACTS WITH A MID-LATITUDE TROUGH MOVING FROM THE GREAT LAKES INTO THE NORTHEASTERN U.S.  GIVEN THE LARGE SHIFT IN THE MODELS…THE OFFICIAL FORECAST HAS BEEN ADJUSTED TO THE LEFT…OR WEST…BUT STILL LIES ON THE EASTERN EDGE OF THE GUIDANCE SUITE.

    THIS IS A GOOD TIME TO REMIND EVERYONE THAT NHC AVERAGE TRACK FORECAST ERRORS ARE 200 TO 300 MILES AT DAYS 4 AND 5.  GIVEN THIS UNCERTAINTY…IT IS TOO SOON TO DETERMINE WHAT…IF ANY…PARTS OF THE U.S. EAST COAST MIGHT SEE DIRECT IMPACTS FROM EARL LATER THIS WEEK.
