TROPICAL DEPRESSION ELEVEN-E DISCUSSION NUMBER   1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 AM PDT WED SEP 03 2003
 
AT 12Z...SOCORRO REPORTED A SOUTH WIND WITH A 1001.6 MB
PRESSURE...AFTER REPORTING A NORTH WIND LAST NIGHT. IN ADDITION...
RECENT SATELLITE IMAGERY THAT INDICATES THE CONVECTION ASSOCIATED
WITH THE TROPICAL DISTURBANCE HAS BECOME MORE CONCENTRATED NEAR
SOCORRO. THE QUIKSCAT PASS AT 01Z SHOWED A DECENT...IF BROAD
CIRCULATION. BASED ON THE ABOVE...THE DISTURBANCE HAS BEEN UPGRADED
TO TROPICAL DEPRESSION ELEVEN-E...EVEN THOUGH SATELLITE
CLASSIFICATIONS ARE T1.0...AT BEST.

IT IS DIFFICULT TO PINPOINT THE POSITION OF THE CENTER AT
THIS TIME...AND THE SYSTEM MAY HAVE TO BE RELOCATED CLOSER TO THE
NORTHEAST EDGE OF THE CONVECTION AFTER MORE VISIBLE IMAGERY BECOMES
AVAILABLE.  THE INITIAL MOTION IS UNCERTAIN BUT ESTIMATED TO BE
295/8.  CURRENTLY A MID-LEVEL RIDGE EXISTS TO THE NORTH OF THE
DEPRESSION.  THE OFFICIAL FORECAST FOLLOWS THE GFS...WHICH SEEMED
TO INITIALIZE THE SYSTEM BETTER THAN THE OTHER GLOBAL MODELS.  THE
GFS BUILDS THE RIDGE WESTWARD OVER THE NEXT COUPLE OF
DAYS...KEEPING THE CYCLONE ON A WEST-NORTHWEST TO WEST TRACK.

THE DEPRESSION IS UNDER THE INFLUENCE OF MODEST NORTHEASTERLY SHEAR. 
THE SHIPS MODEL FORECASTS SLOW STRENGTHENING UNTIL THE SYSTEM
REACHES COOLER WATERS IN 48-72 HOURS.  GIVEN THE LARGE...SPRAWLING
NATURE OF THE TROPICAL CYCLONE...RAPID INTENSIFICATION IS NOT
EXPECTED.
