GMZ500-GMZ501-101800- 1230 AM CDT Fri Oct 10 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Persistent north-northeast winds of 15 to 25 knots and rough seas ranging from 3 to 5 feet in the tidal lakes and sounds to 5 to 8 feet in the open Gulf waters will be the rule through Saturday. These conditions are in response to a low off the coast of Florida and a high centered over the Southern Plains. These rough conditions will keep a small craft advisory in place for all of the waters through Saturday. Sunday will see the high over Texas become more centered over the region. As this occurs, winds will quickly drop to around 10 knots and turn more variable. These lighter winds and gradually improving seas will persist through Monday. A weak front will slip through the waters on Tuesday, and a more persistent northerly wind of 10 to 15 knots will take hold behind the front for both Tuesday and Wednesday. . $$ GMZ530-101800- Lake Pontchartrain and Lake Maurepas- 1230 AM CDT Fri Oct 10 2025 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH SATURDAY MORNING... .REST OF TONIGHT...Northeast winds 15 to 20 knots, diminishing to 10 to 15 knots late.
