SYNOPSIS FOR THE GULF OF AMERICA
1112 AM EDT FRI MAR 20 2026
SYNOPSIS
THE PRESSURE GRADIENT BETWEEN A RIDGE ACROSS THE
GULF REGION AND A WEAKENING STATIONARY FRONT OVER THE CENTRAL
CARIBBEAN SEA WILL CONTINUE TO SUPPORT FRESH TO LOCALLY STRONG NE
WINDS AND MODERATE TO ROUGH SEAS OVER THE SE GULF, INCLUDING THE
STRAITS OF FLORIDA, THROUGH LATE TODAY. MODERATE TO FRESH NE WINDS
ARE EXPECTED NIGHTLY, THROUGH THE FORECAST PERIOD, ACROSS THE
EASTERN BAY OF CAMPECHE DUE TO LOCAL EFFECTS ASSOCIATED WITH A
THERMAL TROUGH. ELSEWHERE, MODERATE OR WEAKER WINDS, AND SLIGHT TO
MODERATE SEAS WILL PREVAIL THROUGH TUE NIGHT.
