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

.SYNOPSIS FOR MID ATLC WATERS...A warm front will develop near
the coast this afternoon, then lift N through the central and N
waters late today or this evening as a cold front approaches from
the W. The cold front will move SE across the N and central
waters tonight through Mon, then stall over the S waters Mon
night as high pressure builds in across the N waters. Low
pressure will develop along the stationary front just inland over
the SE U.S. Mon night, with the low intensifying while lifting NE
from near the Outer Banks Tue to near Georges Bank Tue night. A
cold front extending S from the low will move quickly E and SE
across the waters late Tue into Tue night. High pressure will
build over the waters Wed, and persist Wed night. Yet another
cold front will move across the N and central portions late Thu
before stalling across the S waters Thu night. Mariners should
monitor the latest forecasts for the intensifying low pressure
system set to impact the region late Mon night into Wed, and
begin to strongly consider avoidance routing at this time.
