West central North Atlantic continental shelf and slope waters
beyond 20 nm to 250 nm offshore, including south of Georges Bank
from 1000 fm to 250 nm offshore.

Conditions given represent the highest within that period.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

Locally higher winds and seas can be expected in and near tstms.

.SYNOPSIS FOR MID ATLC WATERS...A stationary front will persist
just S of the area tonight, while a low pressure trough extends
along the coast. High pressure will persist N of the waters
tonight, then shift NE Sat. To the S, low pressure along the E
Florida coast will deepen and expand as it moves N tonight
through Sun, eventually being centered just offshore of the
Virginia Capes Sun night. This broad, complex low will move very
slowly E from the Virginia Capes to the outer Mid-Atlantic Waters
Sun night through Tue night, before clearing E of the area Wed.
Mariners must monitor later forecasts on the coastal system, and
begin to consider avoidance plans as needed. This will be a long
duration event for the east coast, impactful to the mariner. A
cold front will approach from the NW later Wed and Wed night.
