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.

Locally higher winds and seas can be expected in and near tstms.

.SYNOPSIS FOR NEW ENGLAND WATERS...A warm front will develop and
move N over the area this afternoon, and reach the Gulf of Maine
Sun tonight. A cold front will sweep E across the waters tonight,
and move well E of the area Mon. High pressure will build E
across the area late Mon, persist Mon night, and then move
quickly off to the E early Tue. Intensifying low pressure will
approach the waters from the SW early Tue and move into the area
late Tue into Tue night. The low will rapidly exit NE of the
region Wed before high pressure quickly moves across the waters
Wed night. Yet another cold front will move across the area Thu
before exiting to the E and SE late Thu night. Mariners should
monitor the latest forecasts for the intensifying low pressure
system set to impact the region Tue into Wed, and begin to
strongly consider avoidance routing at this time.
