SYNOPSIS FOR THE GULF OF AMERICA
1014 PM EDT SUN SEP 20 2026
SYNOPSIS
WEAK SURFACE RIDGING ACROSS THE SOUTHEASTERN U.S.
WILL MAINTAIN GENERALLY GENTLE TO MODERATE WINDS ACROSS THE BASIN
THROUGH MID WEEK. A VIGOROUS UPPER-LEVEL LOW AND ASSOCIATED
SURFACE LOW OR TROUGH OVER THE CENTRAL GULF WILL CONTRIBUTE TO
SCATTERED SHOWERS AND THUNDERSTORMS OVER THE EASTERN GULF THROUGH
THE MIDWEEK, WITH THE STRAITS OF FLORIDA THE MOST ACTIVE AREA.
A COLD FRONT MAY SINK INTO THE NORTHERN GULF THU NIGHT THROUGH
FRI, LEADING TO A MODEST INCREASE IN WINDS ACROSS THE BASIN.
