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 cold front will stall over or
near the far S waters tonight through Fri night. High pressure
builds S behind the front, 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 offshore of the E Florida coast along the
stalled front Fri night. The low will deepen and expand as it
moves N late Fri night through Sun, eventually being centered off
of the mid-Atlantic coast 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 through Tue
night. 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.
