A NOAA RECONNAISSANCE PLANE HAS BEEN INVESTIGATING THE TROPICAL
DEPRESSION IN THE GULF OF MEXICO AND SO FAR THE OBSERVATIONS
INDICATE THAT THE SYSTEM CONSISTS OF A BROAD CIRCULATION WITH 25-
KNOT WINDS. ON THE OTHER HAND....VISIBLE SATELLITE IMAGES INDICATE
THAT THE CLOUD PATTERN IS BECOMING BETTER ORGANIZED WITH A
LARGE AREA OF THUNDERSTORMS ALONG WITH SOME CYCLONICALLY CURVED
CONVECTIVE BANDS AND A WELL-ESTABLISHED UPPER-TROPOSPHERIC OUTFLOW.
THE UPPER-LEVEL WINDS ARE FAVORABLE FOR STRENGTHENING AND THE
DEPRESSION IS FORECAST TO REACH THE COAST WITHIN THE WARNING AREA
AS A TROPICAL STORM.

THE DEPRESSION IS MOVING TOWARD THE WEST-NORTHWEST OR 300 DEGREES AT
12 KNOTS. THE MOTION OF THE CYCLONE IS BEING CONTROLLED BY A LARGE
HIGH PRESSURE SYSTEM OVER THE SOUTHERN UNITED STATES. THIS PATTERN
IS EXPECTED TO PERSIST...SO NO SIGNIFICANT CHANGE IN MOTION IS
ANTICIPATED BEFORE LANDFALL ON THURSDAY.  THE TRACK GUIDANCE IS
TIGHTLY PACKED AND BRINGS THE CYCLONE TO THE SOUTHERN TEXAS COAST
IN ABOUT 24 HOURS.
