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...High pressure extending W into
the S waters will shift E today as a cold front approaches. The
front, with weak low pressure along it today over the N waters,
will move over the N and central waters today and tonight,
reaching the far S waters late today and tonight before stalling
over or near the far S waters from late tonight through Fri
night. Behind the front, high pressure builds S, resulting in
counterflow to the Gulf Stream and the potential for steeper,
breaking waves. High pressure then continues over the N and
central waters into Fri night, and then over the far N waters
into Sat. To the S, low pressure should form along the stalled
cold front on Fri. The low will deepen and expand as it moves N
Fri night through Sun, eventually being centered off of the mid-
Atlantic coast Sun night. Mariners should monitor later forecasts
on this coastal system, and begin to consider avoidance plans
for the weekend.
