DEVELOPING SURFACE TROUGH IN THE SE BAY OF CAMPECHE IS TRIGGERING
SCATTERED TO NUMEROUS STRONG CONVECTION OVER THE BAY OF CAMPECHE,
AS WELL AS SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ACROSS
THE GULF S OF 27N. OTHERWISE, A 1021 MB HIGH IS INTERACTING WITH
THE DEVELOPING SURFACE TROUGH TO INDUCE FRESH TO STRONG E WINDS IN
THE SE BAY OF CAMPECHE, WITH LOCALLY STRONGER WINDS IN AREAS OF
CONVECTION. MODERATE TO FRESH TRADES PREVAIL ACROSS THE GULF
BETWEEN 21-25N, WITH GENTLE TO MODERATE WINDS ELSEWHERE. SLIGHT
