NWS Ocean Prediction Center Washington DC

Conditions given represent the highest within that period.

...Please refer to Coastal Waters Forecasts (CWF) available
through NOAA Weather Radio and other means for detailed coastal
waters forecasts...

.SYNOPSIS...High pressure will continue to build over the area
behind a cold front now south of the waters. Aside from a trough
or secondary cold front moving south over the area today, high
pressure then continues through Fri night. The high will
gradually shift NE Sat through Sun as a coastal low moves N just
offshore of the SE U.S. The low will strengthen and expand as it
moves N, being centered just offshore of the mid-Atlantic coast
by Sun night. The broad, complex low will extend over much of the
east coast Sun night and Mon, with the broad low finally starting
to shift E Mon night. Mariners should monitor later forecasts on
the coastal system. This will be a long duration event for the
east coast, impactful to the mariner.
