TROPICAL STORM DALILA DISCUSSION NUMBER  20
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP072007
200 PM PDT THU JUL 26 2007
 
DALILA IS RAPIDLY BECOMING A TIGHT SWIRL OF LOW CLOUDS AS IT MOVES
OVER COOLER WATER. THERE ARE STILL SOME PATCHES OF DEEP CONVECTION
BUT THE TOPS ARE WARMING FAST. A QUIKSCAT PASS AT 1330 UTC EARLIER
TODAY SUGGESTED THAT THE WINDS ASSOCIATED WITH DALILA WERE 45
KNOTS...A LITTLE BIT STRONGER THAT THE INITIAL INTENSITY OF 40
KNOTS ESTIMATED IN THE PREVIOUS ADVISORY.  HOWEVER...SINCE THEN
DALILA HAS WEAKENED...AND AN INITIAL INTENSITY OF 40 KNOTS FOR THIS
ADVISORY IS A GOOD ESTIMATE. DALILA'S CIRCULATION IS EXPECTED TO
BE OVER 22 TO 23 DEGREE CELSIUS WATERS SOON...SO A CONTINUED
WEAKENING TREND IS ANTICIPATED. DALILA COULD BECOME A REMNANT LOW
AS EARLY AS TOMORROW.
 
THE CYCLONE IS MOVING TOWARD THE WEST-NORTHWEST OR 300 DEGREES AT 8
KNOTS. BECAUSE DALILA IS WEAKENING AND BECOMING A SHALLOW
CYCLONE...IT WILL LIKELY BE STEERED MORE TOWARD THE WEST BY THE
LOW-LEVEL FLOW UNTIL DISSIPATION.
