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 weak warm front or low pressure

trough will slowly lift N over the N waters tonight while

gradually dissipating, as a weak low pressure trough over the

outer waters moves E of the area. Mariners should use caution for

locally gusty winds and rough seas in and near scattered to

numerous locally heavy tstms that will be likely over portions of

the waters. Otherwise, weak low pressure will move E across the N

waters later tonight into Fri while slowly pulling a weak cold

front over the area. The weak low and front will pass E of the

area Fri night. Another warm front will lift N across the waters

Fri night into Sat night, before a cold front crosses the area

late Sat into Sun. A series of secondary cold fronts or low

pressure troughs will move SE over the region Sun night into Tue.

Yet another warm front will extend E over the central waters Tue

night.
