SYNOPSIS FOR THE GULF OF AMERICA
945 AM EDT TUE SEP 29 2026
SYNOPSIS
A FRONTAL TROUGH EXTENDING FROM NEAR TAMPA BAY,
FLORIDA TO NEAR VERACRUZ, MEXICO SUPPORTS SCATTERED SHOWERS AND
THUNDERSTORMS NEAR THE AXIS. THIS FEATURE WILL GRADUALLY DISSIPATE
THROUGH THE EVENING AS HIGH PRESSURE BUILDS IN. GENTLE TO
MODERATE RETURN FLOW WILL PREVAIL, EXCEPT MODERATE TO LOCALLY
FRESH OVER THE WESTERN GULF TONIGHT. WINDS WILL INCREASE TO
MODERATE TO LOCALLY FRESH ACROSS THE BASIN BY WED EVENING AS THE
PRESSURE GRADIENT TIGHTENS. THE GRADIENT WILL WEAKEN FROM WEST TO
EAST BY THE END OF THE WEEK INTO THE WEEKEND AS A FRONT APPROACHES
THE WESTERN PORTION, POSSIBLY MOVING INTO THE BASIN BY THE END OF
THE WEEKEND WITH WEAKENING WINDS AND SUBSIDING SEAS AHEAD OF IT.
