TROPICAL DEPRESSION THIRTEEN-E DISCUSSION NUMBER   6
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP132007
200 PM PDT THU SEP 20 2007
 
DEEP CONVECTION HAS DISSIPATED IN THE SYSTEM DURING THE LAST SEVERAL
HOURS.  A 1422Z QUIKSCAT PASS AND AN 18Z SHIP REPORT NORTHWEST OF
THE CENTER SUGGESTED WINDS OF 25 TO 30 KT.  DVORAK ESTIMATES HAVE
ALSO DROPPED TO 25 KT...WHICH IS CHOSEN AS THE CURRENT INTENSITY.
 
TROPICAL DEPRESSION THIRTEEN LIKELY HAS DECAYED DUE TO COOL SSTS AND
A STABLE AND DRY ATMOSPHERE.  GIVEN THE CONTINUED LACK OF
CONVECTION...THE SYSTEM NO LONGER MEETS THE CRITERION FOR A
TROPICAL CYCLONE AND THIS WILL BE ITS LAST ADVISORY. 
 
THE DISSIPATING TROPICAL CYCLONE IS MOVING TOWARD THE WEST AT ABOUT
4 KT DUE TO THE INFLUENCE OF A WEAK RIDGE TO ITS NORTH.  LOW-LEVEL
STEERING SHOULD NEARLY COLLAPSE IN THE NEXT DAY OR SO WITH A TURN
BACK TO THE EAST INDICATED BETWEEN 24 TO 48 HOURS FOR THE REMNANT
LOW.
 
FOR ADDITIONAL INFORMATION ON THE REMNANT LOW PLEASE SEE HIGH SEAS
FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS
