GMZ500-GMZ501-030600- 1127 AM CST Tue Dec 2 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... The low pressure that has been in the Gulf has been moving off to the northeast across southern Georgia this morning. The winds on the backside of the low have remained elevated with gusts over 20 knots. However, a surface high pressure will be building in throughout this afternoon and this evening, so expect winds to keep relaxing throughout the rest of the day today. Conditions will remain benign through Wednesday and Thursday morning. Another low pressure is expected to form in the northwestern Gulf. This will enhance winds and rain chances again during the day Thursday. Rain will stick around, but winds will likely relax as the front associated with the low hangs around through Friday. $$ GMZ530-030600- Lake Pontchartrain and Lake Maurepas- 1127 AM CST Tue Dec 2 2025 ...SMALL CRAFT ADVISORY IN EFFECT UNTIL 3 PM CST THIS AFTERNOON... .THIS AFTERNOON...North winds 10 to 15 knots with gusts up to 20 knots.
