IMAGERY, WEATHER OBSERVATIONS, RADAR AND METEOROLOGICAL ANALYSIS.
BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1700 UTC.
..TROPICAL WAVES
A CENTRAL CARIBBEAN TROPICAL WAVE IS NEAR 80W, SOUTH OF 19N,

SHOWERS AND THUNDERSTORMS ARE NOTED ALONG THE MONSOON TROUGH AND
E OF 30W.
..GULF OF AMERICA
DIVERGENCE ALOFT SUPPORTS SCATTERED SHOWERS OVER THE NORTH-
CENTRAL AND NE GULF WATERS. SCATTERED MODERATE CONVECTION IS ALSO
OCCURRING IN THE FAR SW GULF ALONG A SURFACE TROUGH. RIDGING
