 TROPICAL DEPRESSION TEN-E SPECIAL DISCUSSION NUMBER   1
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP102009
 900 AM PDT WED AUG 12 2009
  
 A QUIKSCAT PASS AT 13Z INDICATES THAT THE BROAD AREA OF LOW PRESSURE
 SEVERAL HUNDRED MILES SOUTHWEST OF THE SOUTHERN BAJA PENINSULA HAS
 DEVELOPED A WELL-DEFINED CENTER OF CIRCULATION...AND ADVISORIES ARE
 BEING INITIATED.  THE QUIKSCAT WIND VECTORS ARE IN AGREEMENT WITH
 DVORAK CLASSIFICATIONS OF T2.0 AND THE INITIAL INTENSITY IS
 ESTIMATED TO BE 30 KT.  
 
 THE INITIAL MOTION IS ESTIMATED AT 290/14...BUT IS UNCERTAIN DUE TO
 A LACK OF GOOD HISTORY ON THE CENTER.  THE DEPRESSION IS LOCATED TO
 THE SOUTH OF DEEP-LAYER HIGH PRESSURE AND THE DYNAMICAL MODELS ARE
 IN GOOD AGREEMENT THAT THIS FEATURE WILL DOMINATE THE STEERING OVER
 THE NEXT FEW DAYS.  BY THE END OF THE FORECAST PERIOD THE CYCLONE
 SHOULD BE WEAKENING OVER COOLER WATERS AND MOVING WESTWARD WITH THE
 LOWER-TROPOSPHERIC FLOW.  THE OFFICIAL FORECAST IS CLOSE TO THE
 DYNAMICAL MODEL CONSENSUS.
 
 THE DEPRESSION IS OVER WARM WATERS AND THE SHEAR IS LIGHT EASTERLY. 
 THIS WOULD FAVOR STRENGTHENING...AT LEAST UNTIL THE CYCLONE
 ENCOUNTERS COOLER WATERS IN ABOUT THREE DAYS.  THE OFFICIAL
 FORECAST IS ALONG THE HIGH END OF THE MODEL GUIDANCE...IN GOOD
 AGREEMENT WITH SHIPS AND HWRF.  THE OFFICIAL FORECAST DOES NOT SHOW
 AS MUCH DECAY AS SHIPS LATE IN THE PERIOD BECAUSE THAT MODEL WAS
 BASED ON THE BAMM TRACK...WHICH LIES WELL TO THE NORTH OF THE
 OFFICIAL FORECAST.
