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

.SYNOPSIS FOR NEW ENGLAND WATERS...Low pressure is centered SE of
the region and will continue moving E while strengthening today.
High pressure will build S over the area today, and then persist
through Mon. Another low will form and move E along a front just
S of the waters late Mon through Tue night as a high pressure
ridge slowly weakens over the area. The low will weaken to the SE
and E of the region Wed. A warm front will lift NE over the
waters Wed night into Thu, followed by a cold front approaching
the coast from the W late Thu. The cold front will then move
offshore Thu night.
