Marine Weather and Tide Forecast for Laplace, LA

LONG TERM
(Saturday night through Thursday)
Issued at 316 AM CDT Fri May 23 2025

Sunday may see this isolated storm development as well but a new front will begin to move in from the NW by the start of the new week which will cause more sh/ts to develop well ahead of this front for Mon while becoming more numerous as the front moves into the area Tue. This should cause the best chance of rainfall across the area with more scattered coverage. Numbers supporting severe storms are higher to the north and NW of the area for Mon and Tue but there is evidence that support at least a low risk of severe storms Mon and Tue and possibly Wed as this front may stall near or at the coast.

AVIATION

Issued at 316 AM CDT Fri May 23 2025

VFR conditions for most sites through this cycle. HUM, MSY, NEW and BTR will have a chance of getting TS today and this could initiate PROB30 lines for those sites for this afternoon. There could be some low level cigs in the IFR range develop late tonight into early Fri mainly toward MCB.

MARINE
Issued at 316 AM CDT Fri May 23 2025

The stalled front at the coast moves back north today and the light and variable winds will become established SE again around 10-15kt over all waters. This is already occurring and will continue offshore. There is a chance of storms with this front again today which could cause winds and seas to rapidly rise in and around them.
South to SE winds will remain through the weekend but should remain manageable around 10-15kt. The best chance of storms may show up Tue as some storms over land could rush southward over the northern gulf waters by late afternoon or even overnight Tue night.
