SYNOPSIS FOR THE GULF OF AMERICA
1117 PM EDT THU OCT 23 2025
SYNOPSIS
A WEAK COLD FRONT EXTENDS WESTWARD FROM MARCO ISLAND,
FLORIDA TO 26N89W, THEN TURNS NORTHWESTWARD AS A STATIONARY FRONT
TO BEYOND EASTERN TEXAS. THE ENTIRE FRONTAL BOUNDARY WILL STALL
LATER TONIGHT AND THEN DISSIPATE ON FRI. GENTLE TO MODERATE NE
WINDS AT THE EASTERN GULF WILL BECOME FRESH TO STRONG BY EARLY FRI
AFTERNOON, AND SE WINDS AT THE NORTHWESTERN AND NORTH-CENTRAL GULF
WILL FOLLOW THE SAME TREND BY FRI NIGHT IN RESPONSE TO A STRONG
HIGH PRESSURE PASSING NORTH OF THE GULF. ROUGH SEAS ARE ALSO
EXPECTED ACROSS THE SOUTHEASTERN GULF, INCLUDING THE FLORIDA
STRAITS BY FRI EVENING. AS THE HIGH SLIDED EASTWARD INTO THE
ATLANTIC EARLY NEXT WEEK, THESE WINDS AND SEAS SHOULD SUBSIDE.
