Latest Marine Discussion:

.MARINE... Gusty south to southwest flow will remain given the gradient between high pressure offshore and a slow-moving cold front approaching from the Great Lakes region. Additional SCAs may be needed in the wake of the front with east to southeast flow Wednesday night into Thursday. Shower and thunderstorm chances return to the waters Wednesday afternoon and evening as a cold front drops into the area. Wind direction is a bit uncertain Thursday as a front will be stalled near the area. With the front likely pushing back north of the area Friday, southerly winds will prevail into Saturday. Winds Friday likely result in SCA conditions across the waters. More uncertainty Saturday, with winds nearing SCA criteria especially late. Update as of: 1028 AM EDT Tue Mar 31 2026
