ALTHOUGH A FEW THUNDERSTORMS HAVE REDEVELOPED OVER THE SOUTHEASTERN
PORTION OF THE CIRCULATION THIS AFTERNOON...DALILA BARELY QUALIFIES
AS A TROPICAL CYCLONE.  THE INITIAL WIND SPEED IS SET AT 35 KT 
AND IS SUPPORTED BY RECENT ASCAT DATA AND A BLEND OF THE VARIOUS
DVORAK T- AND CI-NUMBERS.  DRY AIR AND MODERATE EASTERLY SHEAR ARE
EXPECTED TO CONTINUE TO CAUSE THE CYCLONE TO GRADUALLY WEAKEN EVEN
THOUGH IT WILL REMAIN OVER SSTS OF 26 TO 27 DEGREES CELSIUS FOR
ANOTHER 24 HOURS OR SO.  DALIA IS FORECAST TO DEGENERATE TO A
REMNANT LOW IN ABOUT 24 HOURS...BUT THIS COULD OCCUR SOONER.
 
DALILA IS MOVING WESTWARD AT ABOUT 6 KT. A WEST TO WEST-NORTHWEST
MOTION IS EXPECTED TO CONTINUE DURING THE NEXT COUPLE OF DAYS.  
THE LATEST GUIDANCE HINTS AT MORE INTERACTION BETWEEN DALIA AND 
THE TROPICAL DEPRESSION TO ITS SOUTHEAST.  THIS IS LIKELY TO 
CAUSE THE POST-TROPICAL CYCLONE TO DECELERATE IN 2 TO 3 DAYS.  
THE UPDATED NHC TRACK FORECAST IS ONCE AGAIN SLOWER THAN THE
PREVIOUS ADVISORY AFTER 36 TO 48 HOURS.
