Tropical Storm HARVEY


ZCZC MIATCDAT3 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM HARVEY DISCUSSION NUMBER  17
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT SAT AUG 06 2005
 
DEEP CONVECTION CONTINUES JUST NORTHEAST OF THE CENTER.  A QUIKSCAT
PASS AT 09Z INDICATES WINDS OF 50-55 KT...AND THE ADVISORY
INTENSITY IS INCREASED TO 50 KT ON THIS BASIS.  SOME ADDITIONAL
STRENGTHENING IS POSSIBLE DURING THE NEXT 12 HOURS BEFORE HARVEY
ENCOUNTERS COOLER WATERS.  GLOBAL MODEL GUIDANCE INDICATES THAT
HARVEY COULD RE-INTENSITY AS AN EXTRATROPICAL CYCLONE.

THE MOTION HAS TURNED MORE TO THE NORTH...010/6...AND THE LAST
COUPLE OF SATELLITE IMAGES SUGGEST THAT THE CENTER MIGHT ACTUALLY
HAVE MEANDERED TO THE NORTHWEST.  WATER VAPOR IMAGERY SHOWS THE
NEXT SHORT WAVE IN THE WESTERLIES OFF OF NEW ENGLAND IS PUSHING
EASTWARD.  THIS SHOULD INDUCE A GRADUAL BEND OF THE TRACK TO THE
NORTHEAST AND EVENTUALLY EAST-NORTHEAST OVER THE NEXT 48 HOURS. 
THE OFFICIAL FORECAST IS A LITTLE SLOWER THAN THE PREVIOUS ADVISORY
AND FAVORS THE GFDL OVER THE GFS INITIALLY...AS THE MOST RECENT RUN
OF THE GFDL SEEMS TO HAVE BETTER CAPTURED THE RECENT LEFT TURN.
