Tropical Depression ALVIN


ZCZC MIATCDEP1 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION ALVIN DISCUSSION NUMBER  19
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP012007
800 AM PDT THU MAY 31 2007
 
ALVIN HAS LOST ALL DEEP CONVECTION THIS MORNING...AND AN EXPOSED
LOW-LEVEL CIRCULATION IS CLEARLY EVIDENT ON NIGHT-VIS IMAGES.  THE
INITIAL INTENSITY WILL BE REDUCED TO 25 KT IN ACCORDANCE WITH THE
LATEST SATELLITE ESTIMATES FROM TAFB/SAB.  THE TROPICAL CYCLONE
LOOKS TO BE ON A FAST TRACK TO DEGENERATING INTO A NON-CONVECTIVE
REMNANT LOW...PERHAPS AS EARLY AS THIS AFTERNOON.  

OVERNIGHT SATELLITE IMAGERY SHOWS THAT ALVIN IS CREEPING TO THE
WEST-SOUTHWEST...250/2. MODELS CONTINUE THE WEST-SOUTHWESTWARD
TRACK FOR A FEW DAYS DUE TO WEAK LOW-LEVEL RIDGING TO THE NORTH.
THE FORECAST TRACK IS NUDGED A LITTLE SOUTH OF THE PREVIOUS
FORECAST AND IS ALSO A TOUCH SLOWER SINCE THE DEPRESSION HAS BEEN
STUBBORNLY REFUSING TO MOVE MUCH.
