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...Low pressure just S of the waters
will deepen and expand as it moves N tonight through Sun, with a
secondary low forming Sun, and eventually being centered 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, and
impactful to the mariner. A cold front will approach from the NW
late Tue night into early Wed. The front will then move offshore
late Wed into Wed night, then clear E of the area by Thu. High
pressure will build in across the waters Thu and Thu night.
