HOW MUCH THIS RIDGE WILL WEAKEN IS CRITICAL FOR THE LONGER-RANGE TRACK OF THIS HURRICANE. THE OFFICIAL FORECAST TRACK IS SIMILAR TO THE PREVIOUS ONE AND VERY CLOSE TO THE MODEL CONSENSUS AND THE LATEST FSU SUPERENSEMBLE FORECAST. ONE CONCERN IS THAT THE GFDL MODEL FORECAST TRACK HAS GENERALLY BEEN SHIFTING MORE WESTWARD WITH EACH SUCCESSIVE RUN. IT IS EXTREMELY IMPORTANT NOT TO FOCUS ON THE EXACT TRACK... ESPECIALLY AT 96 AND 120 HOURS...BECAUSE THE HURRICANE IS NOT A POINT AND FORECASTS AT THESE EXTENDED TIME RANGES CAN EASILY HAVE ERRORS OF SEVERAL HUNDRED MILES. Straight from the horse's mouth, the 11am NHC discussion. Everybody needs to be weary and cautious with Frances. |
