SYNOPSIS FOR THE GULF OF AMERICA
351 PM EDT TUE SEP 29 2026
SYNOPSIS
A FRONTAL TROUGH EXTENDING FROM NEAR TAMPA BAY,
FLORIDA TO NEAR VERACRUZ, MEXICO SUPPORTS SCATTERED SHOWERS AND
THUNDERSTORMS EAST OF THE AXIS MAINLY IN THE SE GULF. 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. INCREASING WINDS AND BUILDING SEAS ARE
POSSIBLY BEHIND THE VERY SLOW MOVING FRONT.
