 TROPICAL STORM HARVEY DISCUSSION NUMBER  19
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
 11 PM EDT SAT AUG 06 2005
 
 AFTER MOST OF THE DAYLIGHT HOURS WITH HARVEY'S CIRCULATION
 EXPOSED...LATEST SATELLITE IMAGES INDICATE THE CENTER IS TUCKED
 UNDER THE CONVECTION ONCE AGAIN.  EVEN THOUGH THE STRONGEST WINDS
 ARE MAINLY NORTHEAST OF THE CENTER...CONFIRMED BY A RECENT QUIKSCAT
 PASS...THE OVERALL APPEARANCE OF HARVEY ON SATELLITE REMAINS
 SURPRISINGLY GOOD. WATER VAPOR IMAGERY DEPICTS A DIGGING SHORT WAVE
 TROUGH EAST OF THE NORTHEAST U.S. COAST. THE APRROACHING TROUGH MAY
 BE AIDING IN HARVEY'S PERSISTENCE IN REMAINING A 50 KT TROPICAL
 STORM DUE TO TROUGH INTERACTION.  
 
 HARVEY IS FINALLY SUSTAINING A NORTHEAST MOTION AT 040/8. AS THE
 SHORT WAVE APPROACHES...THE STEERING FLOW SHOULD ACCELERATE HARVEY
 SLIGHTLY TO THE NORTHEAST OVER THE NEXT DAY OR SO.  THEREAFTER...
 HARVEY IS FORECAST TO BEGIN EXTRATROPICAL TRANSITION AS THE STORM
 MOVES OVER THE COLD NORTH ATLANTIC WATERS.  GLOBAL MODELS CONTINUE
 TO SHOW THAT EXTRATROPICAL HARVEY MAY LINGER FOR A FEW DAYS IN
 EASTERN ATLANTIC.
