Tropical Storm FELICIA


ZCZC MIATCDEP1 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM FELICIA DISCUSSION NUMBER   6
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2 AM PDT SAT JUL 19 2003
 
THE INITIAL MOTION ESTIMATE IS 275/15.  THE GLOBAL GUIDANCE MODELS
CONTINUE TO SHOW A WEST TO WEST-NORTHWESTWARD TRACK FOR THE NEXT
FIVE DAYS WITH A STRONG RIDGE TO THE NORTH.  THERE IS ALSO A
MID/UPPER-LEVEL TROUGH NORTHWEST OF THE STORM...BUT NONE OF THE
GUIDANCE APPEARS TO REFLECT THIS FEATURE IN THEIR TRACK FORECASTS
AND NEITHER DOES THE OFFICIAL FORECAST WHICH FOLLOWS A BLEND OF THE
GLOBAL MODELS.
 
A CDO FEATURE PERSISTS NEAR AND SOUTH OF THE CENTER.  THE INITIAL
WIND SPEED ESTIMATE IS 40 KNOTS...INHERITED FROM THE PREVIOUS
ADVISORY AND SUPPORTED BY DVORAK ESTIMATES.  MICROWAVE DATA
SUGGESTS THE WIND SPEED MAY BE LOWER THAN 40 KNOTS.  THE SHIPS
MODEL SUGGESTS MODEST STRENGTHENING FOR 48 HOURS FOLLOWED BY
WEAKENING OVER COOLER WATER AND INCREASING VERTICAL SHEAR.
