TROPICAL DEPRESSION SIX-E DISCUSSION NUMBER   3
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2 PM PDT THU JUL 29 2004

DEEP CONVECTION ASSOCIATED WITH THE SYSTEM IS LIMITED AND NOT
WELL-ORGANIZED...AND LOW CLOUD MOTIONS DO NOT DEPICT AN OBVIOUS
CENTER OF CIRCULATION.  ALSO...DATA FROM A QUIKSCAT PASS FROM
SEVERAL HOURS AGO CAST SOME DOUBT ON THE EXISTENCE OF A DEFINITE
SURFACE CIRCULATION.  SINCE THE SYSTEM IS MOVING OVER WARM WATERS
AND THE VERTICAL SHEAR IS NOT EXCESSIVELY HIGH...THE SYSTEM MAY
SURVIVE AS A TROPICAL CYCLONE THROUGH THE FORECAST PERIOD.  
HOWEVER...GIVEN ITS CURRENT CONDITION...A MORE LIKELY SCENARIO IS
FOR THE DEPRESSION TO DISSIPATE WITHIN A COUPLE OF DAYS IF NOT
SOONER.

ALTHOUGH THE CENTER IS NOT OBVIOUS...MY BEST GUESS IS THAT IT...OR
THE CYCLONIC VORTICITY MAXIMUM...IS SOMEWHAT TO THE SOUTH OF THE
PREVIOUS TRACK.  WITH LOW- TO MID-TROPOSPHERIC RIDGING TO THE
NORTH...A GENERALLY WESTWARD MOTION OF THE TROPICAL CYCLONE...OR
REMNANT LOW...IS LIKELY THROUGH THE PERIOD.
