SYNOPSIS FOR THE GULF OF AMERICA
1119 PM EDT TUE SEP 29 2026
SYNOPSIS
SCATTERED SHOWERS AND ISOLATED THUNDERSTORM OVER THE
E GULF ARE ASSOCIATED WITH A WEAK FRONTAL BOUNDARY. THIS FEATURE
WILL GRADUALLY DISSIPATE TONIGHT 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.
