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...Mariners should use caution in
and near strong thunderstorms which are currently near and off 
the coasts of New Jersey and Delaware, with thunderstorms likely 
becoming more widespread over a good portion of the area through 
Wed and into Thu. The stronger thunderstorms can produce very 
gusty winds and very rough seas. Otherwise, as high pressure 
remains over the S waters, a surface trough will be located over 
the N and central waters tonight through Wed night. A cold front 
approaches from the NW Thu, gradually moving SE across the N 
waters Thu night and Fri as high pressure to the S retreats E. 
The front should weaken and stall over the central waters Fri 
night through Sat, with weak low pressure possibly forming off 
of the SE U.S. coast just S of the front along a surface trough. 
The front should move back N as a weak warm front late Sat and 
Sat night as high pressure builds N. The high continues over 
most of the area Sun and Sun night, with any weak low pressure 
drifting off of the SE coast.
