SYNOPSIS FOR THE GULF OF AMERICA
427 PM EDT WED AUG 13 2025
SYNOPSIS
THE NORTHERN EXTENSION OF A TROPICAL WAVE IS OVER
THE YUCATAN PENINSULA WITH SCATTERED MODERATE CONVECTION IN THE
AREA. THIS ACTIVITY WILL FOLLOW THE WAVE AS IT MOVES WEST THROUGH
THE BAY OF CAMPECHE TONIGHT. SOME TROPICAL DEVELOPMENT IS
POSSIBLE IN THE SW GULF WHILE THE SYSTEM MOVES WNW OR NW, AND
THERE IS A LOW CHANCE OF TROPICAL FORMATION OVER THE NEXT 7 DAYS.
OTHERWISE, GENTLE WINDS AND SLIGHT SEAS ARE EXPECTED THROUGH THE
BASIN AS WEAK HIGH PRESSURE DOMINATES.
