GMZ500-GMZ501-272300- 437 AM CST Thu Nov 27 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... A cold and dry high pressure system will build over the waters through Friday. As this colder and drier air moves across the warmer waters, stronger winds aloft will transport down to the surface. As a result, an extended period of small craft advisory conditons due to northerly winds of 20 knots or greater and rough seas of over 7 feet will impact the waters through Friday. Winds will relax slightly to between 15 and 20 knots and begin to turn more southeasterly and southerly over the weekend as another low pressure system pushes through the region. A weak front will slide offshore and stall over the waters early next week. Winds will shift back to an offshore direction after the front moves through. At the same time, a low pressure system will strengthen over the northern Gulf Monday night into Tuesday. Northerly winds will increase back into small craft advisory range as this low strengthens over the waters. $$ GMZ530-272300- Lake Pontchartrain and Lake Maurepas- 437 AM CST Thu Nov 27 2025 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH FRIDAY MORNING... .TODAY...Northeast winds 15 to 20 knots with gusts up to 25 knots, becoming north 10 to 15 knots with gusts up to 20 knots late this morning and afternoon.
