 TROPICAL DEPRESSION NINE-E DISCUSSION NUMBER   8
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP092009
 800 AM PDT TUE AUG 11 2009
 
 SATELLITE IMAGERY INDICATES THAT THE CENTER OF TROPICAL DEPRESSION
 NINE-E HAS AGAIN BECOME EXPOSED SOUTH AND SOUTHWEST OF THE
 REMAINING CONVECTION...WHICH HAS DECREASED OVER THE PAST SEVERAL
 HOURS.  SATELLITE INTENSITY ESTIMATES REMAIN 35 KT FROM TAFB AND
 SAB.  HOWEVER...THE INITIAL INTENSITY REMAINS 30 KT BASED ON AN
 EARLIER ASCAT PASS AND THE CURRENT LACK OF ORGANIZATION.
  
 THE INITIAL MOTION IS 270/10.  THE DEPRESSION IS LOCATED ON THE
 SOUTH SIDE OF A MID/UPPER-LEVEL RIDGE...WITH THE LARGE-SCALE MODELS
 FORECAST TO BUILD WESTWARD DURING THE NEXT SEVERAL DAYS.  THIS
 SHOULD STEER THE CYCLONE ON A GENERALLY WESTWARD PATH DURING THE
 FORECAST PERIOD.  ONE POTENTIAL PROBLEM IS THAT SOME OF THE MODELS
 FORECAST A DISTURBANCE SOUTHWEST OF THE DEPRESSION TO
 DEVELOP...THUS POSSIBLY CAUSING ERRATIC MOTION AS THE TWO SYSTEMS
 INTERACT.  SINCE THE DISTURBANCE CURRENTLY SHOWS NO SIGNS OF
 DEVELOPMENT...THE FORECAST FOR THE DEPRESSION WILL CALL FOR A
 WESTWARD TRACK SIMILAR TO THE PREVIOUS ADVISORY.  THE NEW FORECAST
 TRACK IS NEAR THE CENTER OF THE MODEL GUIDANCE ENVELOPE.
 
 THE DEPRESSION IS CURRENTLY IN AN ENVIRONMENT OF LIGHT/MODERATE
 WESTERLY VERTICAL WIND SHEAR.  THE LARGE-SCALE MODELS FORECAST
 UPPER-LEVEL EASTERLY FLOW TO DEVELOP OVER THE CYCLONE DURING THE
 NEXT 12-24 HR AND A RESULTING LIGHT SHEAR ENVIRONMENT.  THIS
 SUGGESTS THE POSSIBILITY OF STRENGTHENING.  HOWEVER...MOST OF THE
 INTENSITY GUIDANCE KEEPS THE SYSTEM WEAK...WITH ONLY THE HWRF
 CURRENTLY CALLING FOR THE SYSTEM TO INTENSIFY BEYOND 50 KT.  BASED
 ON THIS...THE INTENSITY FORECAST CALLS FOR MODEST STRENGTHENING IN
 AGREEMENT WITH THE INTENSITY CONSENSUS.  IF THE DISTURBANCE TO THE
 SOUTHWEST DEVELOPS...IT COULD ABSORB TROPICAL DEPRESSION NINE-E AS
 INDICATED BY THE ECMWF AND UKMET MODELS.
