TROPICAL DEPRESSION DEBBY DISCUSSION NUMBER  16
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL042012
500 AM EDT WED JUN 27 2012
 
SATELLITE...RADAR AND SURFACE OBSERVATIONS INDICATE THAT THE
CIRCULATION OF DEBBY IS INCREASINGLY BECOMING ELONGATED. THE CENTER
IS DIFFICULT TO LOCATE GIVEN THE LACK OF ORGANIZATION...BUT THE AREA
OF MINIMUM PRESSURE HAS BEEN MOVING EAST-NORTHEASTWARD OR 075
DEGREES AT 9 KNOTS ACROSS NORTH-CENTRAL FLORIDA. MOST OF THE DEEP
CONVECTION IS IN A FRONTAL-TYPE BAND EXTENDING NORTHEASTWARD FROM
FLORIDA ACROSS THE ADJACENT ATLANTIC.  THE MAXIMUM WINDS ARE STILL
PROBABLY 30 KNOTS IN A FEW SQUALLS MAINLY OVER WATER. 

NONE OF THE INTENSITY GUIDANCE SHOW A SIGNIFICANT INCREASE IN
STRENGTH...AND IN FACT...BOTH THE GFS AND THE ECMWF SUGGEST
WEAKENING IN THE 00 UTC RUN. THE OFFICIAL FORECAST KEEPS DEBBY AS A
TROPICAL DEPRESSION AND ALLOWS SOME SLIGHT STRENGTHENING BEYOND 3
DAYS.

DEBBY IS EMBEDDED IN WESTERLY FLOW WITHIN THE BASE OF A MID-LATITUDE
TROUGH...AND IT SHOULD CONTINUE TO MOVE TOWARD THE EAST-NORTHEAST OR
NORTHEAST AS INDICATED BY GLOBAL MODELS. THE OFFICIAL FORECAST IS
IN BETWEEN THE GFS AND ECMWF MODELS.
