SYNOPSIS FOR THE GULF OF AMERICA
335 PM EDT WED SEP 30 2026
SYNOPSIS
SHOWERS AND THUNDERSTORMS WILL LINGER IN THE SE GULF
THROUGH AT LEAST TONIGHT. THE PRESSURE GRADIENT BETWEEN HIGH
PRESSURE OVER THE EASTERN UNITED STATES AND LOWER PRESSURES IN
TEXAS AND MEXICO SUPPORT INCREASING WINDS TO MODERATE TO FRESH
SPEEDS ACROSS THE BASIN LATER THIS EVENING. THE GRADIENT WILL
WEAKEN FROM WEST TO EAST BY THE END OF THE WEEK INTO THE WEEKEND
AS A FRONTAL BOUNDARY APPROACHES THE WESTERN GULF WATERS,
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 POSSIBLE BEHIND THE VERY SLOW MOVING OR
