Latest Marine Discussion:
.MARINE... SCAs through this evening. Sub-SCA level winds return Fri. Winds will shift to the north late Fri into Sat as coastal low pressure passes offshore. A coastal low is likely to develop off the Carolina coastline early this weekend, then rapidly track northeast near the Eastern Seaboard through early Mon. As the low approaches, expect winds to increase over the waters. The strongest winds will arrive Saturday night into Monday morning as the low pressure makes its closest approach to the local waters. Gale conditions are becoming likely, with gusts of at least 35-40 kt over most of the waters. Some model guidance indicates gusts to near storm force (50 kt) are possible in the open waters of the central to southern Chesapeake Bay. This will all depend on how close the low tracks. Will let day shift evaluate latest guidance and potentially issue a Gale Watch. Regardless, dangerous and life threatening marine conditions are likely over the waters this weekend. Update as of: 232 AM EST Thu Jan 29 2026
