SYNOPSIS FOR THE GULF OF AMERICA
1105 AM EDT SUN JUL 20 2025
SYNOPSIS
RELATIVELY WEAK HIGH PRESSURE WILL PREVAIL ACROSS
THE BASIN THROUGH THE MIDDLE OF THE WEEK PRODUCING GENTLE TO
MODERATE WINDS ALONG WITH SLIGHT TO MODERATE SEAS. FRESH TO
LOCALLY STRONG NORTHEAST TO EAST WINDS WILL PULSE ALONG THE
YUCATAN PENINSULA EACH AFTERNOON AND EVENING WELL INTO THE
WEEK AS A TROUGH DEVELOPS INLAND DAILY AND SHIFTS WESTWARD OVER
THE BAY OF CAMPECHE AT NIGHT. LOOKING AHEAD, WINDS MAY INCREASE TO
FRESH SPEEDS ACROSS THE NE GULF BY THU AS BROAD LOW PRESSURE
MOVES ACROSS THE SOUTHEASTERN U.S. BEFORE POSSIBLY MOVING FROM E
TO W ACROSS THE NORTHERN GULF. WIDESPREAD SHOWERS AND THUNDERSTORMS
ARE EXPECTED OVER MOST OF THE EASTERN AND NORTH- CENTRAL GULF
WATERS STARTING TUE.
