TROPICAL DEPRESSION TEN-E DISCUSSION NUMBER  12
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2 PM PDT WED SEP 14 2005
 
DEEP CONVECTION HAS DECREASED THIS AFTERNOON IN ASSOCIATION WITH
TROPICAL DEPRESSION TEN-E...WITH MOST OF THE REMAINING CONVECTION
FOUND IN BANDS TO THE NORTH AND SOUTH OF THE CENTER.  AN EARLIER
QUIKSCAT OVERPASS SHOWED A FEW 40 KT WINDS...BUT HOW GOOD THESE ARE
IS UNCERTAIN DUE TO RAIN CONTAMINATION ISSUES.  THE INITIAL
INTENSITY REMAINS 30 KT.

THE INITIAL MOTION IS 260/10.  LARGE-SCALE MODELS INDICATE DEEP-
LAYER RIDGING SHOULD PREVAIL NORTH OF THE CYCLONE THROUGH 72 HR...
TAKING THE SYSTEM ON A GENERALLY WESTWARD TRACK.  MOST MODELS SHOW
THIS TRACK...ALTHOUGH THE GFS HAS A PROLONGED WEST-SOUTHWESTERLY
MOTION NOT SHOWN BY THE OTHER MODELS.  AFTER 72 HR...THE
LARGE-SCALE MODELS SHOW AN MID/UPPER-LEVEL LOW DEVELOPING TO THE
NORTHEAST OF THE HAWAIIAN ISLANDS.  THE UKMET...NOGAPS...GFDL...
AND GFDN RESPOND TO THIS BY TURNING THE SYSTEM NORTHWESTWARD...
WHILE THE GFS CONTINUES A WESTWARD MOTION ALONG 12N.  GIVEN THIS
SPREAD...THE OFFICIAL FORECAST WILL CALL FOR A LITTLE SLOWER MOTION
THAN THE PREVIOUS PACKAGE.  THE NEW FORECAST TRACK IS ALONG THE
LEFT SIDE OF THE CONSENSUS MODELS.
 
OVERALL...CONDITIONS STILL APPEAR TO BE FAVORABLE FOR DEVELOPMENT...
ALTHOUGH THE CURRENT LACK OF CONVECTION NEAR THE CENTER SUGGEST
THAT DEVELOPMENT WILL BE SLOW FOR THE FIRST 12 HR OR SO.  THE GFDL
IS ALONE IN TAKING THE SYSTEM UP TO A HURRICANE...AND THE INTENSITY
FORECAST IS BASED ON THE SHIPS MODEL.  IF THE SYSTEM TURNS MORE
TOWARD THE NORTH THAN CURRENTLY FORECAST AFTER 72 HR...IT WILL
LIKELY BE WEAKER THAN CURRENTLY FORECAST.
