TROPICAL STORM FABIO DISCUSSION NUMBER  23
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP062012
800 AM PDT TUE JUL 17 2012
 
FABIO IS SPINNING DOWN OVER SEA SURFACE TEMPERATURES BELOW 22C. ONLY
A SMALL PATCH OF CONVECTION IS LINGERING TO THE EAST OF THE
ESTIMATED CENTER THIS MORNING. SATELLITE CLASSIFICATIONS CONTINUE
TO FALL...AN AVERAGE OF THE LATEST T- AND CI-NUMBERS FROM
TAFB...SAB...AND UW-CIMSS ADT SUPPORTS LOWERING THE INITIAL WIND
SPEED TO 40 KT. THE LOW- AND MID-LEVEL CENTERS APPEAR TO BE
DECOUPLING DUE TO SOME WESTERLY VERTICAL WIND SHEAR. THE EXPECTED
INCREASE IN SHEAR...ALONG WITH EVEN COLDER WATERS AHEAD AND A DRY
AIR MASS SHOULD CAUSE FABIO TO WEAKEN TO A TROPICAL DEPRESSION LATER
TODAY AND A REMNANT LOW TONIGHT OR EARLY WEDNESDAY. THE GLOBAL
MODELS ARE IN GOOD AGREEMENT IN SHOWING THE REMNANT LOW LOSING ITS
IDENTITY IN 2 TO 3 DAYS.

THE WEAKENING TROPICAL STORM IS MOVING NORTHWARD AT ABOUT 10 KT. A
NORTH-NORTHEASTWARD MOTION WITH A DECREASE IN FORWARD SPEED IS
FORECAST UNTIL THE CYCLONE DISSIPATES.
 
MID- TO UPPER-LEVEL MOISTURE ASSOCIATED WITH THE REMNANTS OF FABIO
IS EXPECTED TO SPREAD NORTHWARD ACROSS PORTIONS OF SOUTHERN
CALIFORNIA IN THE NEXT DAY OR SO.  THIS MOISTURE COULD ENHANCE THE
RAINFALL POTENTIAL ACROSS THAT REGION.
