| #47702 (Received by flhurricane at: 10:48 AM 22.Sep.2005) TCDAT2 TROPICAL STORM PHILIPPE DISCUSSION NUMBER 21 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 11 AM EDT THU SEP 22 2005 DETERMINING A LOW-LEVEL CIRCULATION HAS BEEN DIFFICULT THIS MORNING. THE CENTER THAT WE HAVE BEEN FOLLOWING FOR THE LAST 24 HOURS APPEARS TO BE DISSIPATING WITHIN A BROADER CYCLONIC CIRCULATION...AND SATELLITE REPRESENTATION SHOWS THE OVERALL SYSTEM OBTAINING SUBTROPICAL OR EXTRATROPICAL CHARACTERISTICS RATHER QUICKLY. DVORAK DATA T-NUMBERS ARE ARE 2.5...35 KT FROM TAFB AND 1.5...25 KT FROM SAB. BASED ON A FEW POSSIBLY RAIN CONTAMINATED 35 KT WIND BARBS FROM A RECENT QUIKSCAT PASS...THE INITIAL INTENSITY IS HELD AT 35 KT. THE INITIAL MOTION IS ESTIMATED AT 350/15. WATER VAPOR IMAGERY INDICATES PHILIPPE INTERACTING WITH A STRONG UPPER LEVEL LOW TO THE SOUTHWEST OF THE CYCLONE. GLOBAL MODELS DIFFER IN THE FUTURE TRACK OF THE PHILIPPE/EXTRATROPICAL LOW. THE UKMET MODEL ACCELERATES THE CYCLONE NORTHEASTWARD IN THREE DAYS...WHILE THE GFS MODEL FORECASTS A WEAKENING SLOW DECAY WITH LITTLE NORTHEAST MOTION. THE OFFICIAL FORECAST TAKES A MORE CONSERVATIVE APPROACH...ABSORBING PHILIPPE INTO THE LARGER EXTRATROPICAL CIRCULATION WITHIN 12 HOURS. UNLESS THE REMNANT VORTICITY OF PHILIPPE BECOMES BETTER DEFINED THIS AFTERNOON...ADVISORIES WILL BE DISCONTINUED. IT IS ALSO POSSIBLE FOR PHILIPPE TO REGAIN TROPICAL CHARACTERISTICS IF THE GFS SOLUTION PLAYS OUT.
