FRINGE SHOWERS OR STORMS AFFECTING THE EXTREME SERN ZONES AND ERN
COASTAL WATERS THIS AFTERNOON.

FORECAST TRACK FOR DEBBY BASICALLY FOLLOW LATEST ECMWF RUN...
TAKING THE STORM CENTER ON A SLOW NWD MOVEMENT TOWARD THE MOUTH OF
THE MISSISSIPPI BEFORE PUSHING WWD AS THE RIDGE ALOFT BUILDS
FARTHER SWD. THIS KEEPS THE STORM OVER THE GULF...WITH THE CLOSEST
APPROACH OF THE CENTER BEING ABOUT 130 MILES SOUTH OF THE MOUTH OF

SHOULD KEEP MOST OF THE PRECIP OVER THE COASTAL WATERS...WITH
HIGHEST OVERLAND POPS BEING JUST 20S OVER THE COASTAL ZONES UNTIL
THE LATER 1/2 OF THE PERIOD AS IT MOVES ASHORE ALONG THE TEXAS
COAST AND WEAKENS.
