 TROPICAL DEPRESSION DEBBY DISCUSSION NUMBER  22
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL042006
 1100 PM EDT SAT AUG 26 2006
  
 LATEST INFRARED SATELLITE IMAGERY DEPICTS DEBBY JUST A SWIRL OF
 LOW-LEVEL CLOUDS DEVOID OF ANY DEEP CONVECTION.  DVORAK ESTIMATES
 FROM ALL THREE AGENCIES REMAIN AT 25 KT...AND A 2200 UTC QUIKSCAT
 PASS CONTAINED SOME 25 KT WIND VECTORS SUPPORTING THE SATELLITE
 CLASSIFICATIONS.  BASED UPON THIS INFORMATION THE INITIAL INTENSITY
 REMAINS AT 25 KT.  DEBBY IS FORECAST TO BECOME A REMNANT LOW IN 12
 HOURS...CONTINGENT UPON NO RE-DEVELOPMENT OF ANY DEEP CONVECTION.
 RECENT FSU CYCLONE PHASE DIAGRAMS SHOW TRANSITION TO AN
 EXTRATROPICAL CYCLONE IN 24 HOURS AS THE CYCLONE BECOMES MORE
 INFLUENCED BY THE BAROCLINIC ZONE TO ITS NORTHWEST.  THE OFFICIAL
 FORECAST REFLECTS THIS REASONING AS WELL.
  
 THE INITIAL MOTION IS 330/10.  DEBBY IS CURRENTLY BEING INFLUENCED
 BY A LARGE AMPLITUDE TROUGH OVER THE NORTHWESTERN ATLANTIC AS WELL
 AS AN UPPER-LEVEL LOW TO THE SOUTHWEST OF THE CYCLONE.  THE
 OFFICIAL FORECAST IS CLOSE TO THE PREVIOUS FORECAST WITH ABSORPTION
 OF DEBBY BY THE FRONTAL ZONE OCCURRING IN ABOUT 36 HOURS.
