THERE HAS BEEN A SIGNIFICANT CHANGE IN THE FORECAST TRACK WITH THIS
ADVISORY. THE OFFICIAL FORECAST NO LONGER BRINGS DEBBY WESTWARD
ALONG THE NORTHERN GULF OF MEXICO AND INSTEAD KEEPS THE CYCLONE
MEANDERING OVER THE NORTHEASTERN GULF FOR THE NEXT 3 TO 4 DAYS.
THIS FORECAST IS A COMPROMISE BETWEEN THE CONSISTENT EASTWARD
SOLUTION PROVIDED BY THE GFS FOR THE PAST SEVERAL DAYS AND THE NEW
TWIST OF THE ECMWF. THE ECMWF MODEL...WHICH HAS BEEN
FORECASTING DEBBY TO MOVE WESTWARD ALONG THE GULF OF MEXICO... NOW
HAS THE CYCLONE MEANDERING FOR THE NEXT 3 DAYS OVER THE
NORTHEASTERN GULF. SINCE THESE TWO RELIABLE MODELS ARE IN
MARGINALLY BETTER AGREEMENT...I AM A LITTLE MORE CONFIDENT...BUT
NOT COMPLETELY...THAT DEBBY IS NOT GOING TO TURN WESTWARD OVER THE
GULF. HOWEVER...NEW OFFICIAL TRACK REMAINS A LOW-CONFIDENCE
FORECAST.
DEBBY IS A SPRAWLING SYSTEM...WITH MOST OF THE THUNDERSTORM ACTIVITY
IN A CURVED BAND WELL REMOVED FROM THE CENTER. DATA FROM THE
RECONNAISSANCE PLANE A FEW HOURS AGO INDICATE THAT THE INITIAL
INTENSITY REMAINS 50 KNOTS. THE SHEAR IS NOT EXPECTED TO CHANGE
MUCH FOR THE NEXT DAY OR SO...BUT BECAUSE DEBBY IS FORECAST TO
REMAIN OVER WATER...THERE WILL BE SOME OPPORTUNITY FOR A SLIGHT
STRENGTHENING BEFORE THE CENTER MOVES INLAND. HOWEVER...THE CYCLONE
WILL LOCATED BE NORTH OF THE AREA OF HIGH OCEANIC HEAT CONTENT AND
THE UPWELLING COULD HALT THE INTENSIFICATION.
and just look at how much the models changed from last post.
So it looks like Florida is going to take the brunt of this storm. But like Forecaster Avila mentioned, the new official track has low confidence, so if any thing goes wrong, we'll let you know, so check in daily.
