GMZ500-GMZ501-020830- 240 PM CDT Tue Apr 1 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Southerly and southeasterly winds have already returned and will increase through the tomorrow and remain moderate to strong through the remainder of the week and into the weekend. Not only will onshore flow increase but with high pressure off to our east-northeast and low pressure slowly taking shape over the southern Plain a rather long persistent southeast fetch will set up over the eastern Gulf. This will lead to hazardous boating conditions and well above normal tides across the region and these impacts will last into the weekend before the next cold front late in the weekend or early next week. $$ GMZ530-020830- Lake Pontchartrain and Lake Maurepas- 240 PM CDT Tue Apr 1 2025 ...SMALL CRAFT ADVISORY IN EFFECT FROM 10 PM CDT THIS EVENING THROUGH THURSDAY AFTERNOON... .TONIGHT...Southeast winds 10 to 15 knots, increasing to 15 to 20 knots after midnight.
