the region late tonight through Sat night. Mariners should
consider avoidance plans depending on their vessel type and
cargo. High pressure will build E over the waters Sat through

cold front moves offshore. The front will then move E across the
waters Mon and early Mon night as a low pressure trough crosses
the N waters. High pressure will briefly build E over the S
waters Mon night, then weaken Tue while shifting S of the region.
Another cold front will move offshore Tue night, cross the waters
