New England continental shelf and slope waters from 25 nm
offshore to the Hague Line, except to 1000 fm south of New
England.

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.

.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure currently over
the SE portion will gradually pass E of the waters tonight and
Tue. Low pressure will approach the area from the SW Tue into
Wed, move N across the far SW waters late Wed, then move N into
New England Wed night and Thu. A warm front will lift N across
the area late Wed into Thu as a strong cold front moves E over
the waters. A low pressure trough will pass E through the waters
late Thu and Thu night, before weak high pressure quickly moves E
over the area Fri. Weak low pressure will approach from the SW
Fri night, and move NE over the area Fri night into Sat as
another cold front approaches the region from the NW. The cold
front will move SE over the area Sat night as another low passes
SE of the waters.
