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

.SYNOPSIS FOR NEW ENGLAND WATERS...A weak high pressure ridge
will quickly move E through the area today, followed by another
cold front moving through the waters tonight. High pressure will
again build E over the area Sun and Sun night, then shift E of
the waters early Mon. An area of low pressure will form over the
Mid-Atlantic Mon and push a warm front N across the waters,
followed by the associated cold front moving SE across the area
Mon night as the low lifts NE into the Gulf of Saint Lawrence. A
secondary cold front or low pressure trough will move E across
the waters Tue. Weak high pressure will rapidly pass E over the
area Tue night as developing low pressure approaches the Mid-
Atlantic coast. The low will track NE, passing just S and SE of
the waters Wed and Wed night while a trough or weak cold front
moves quickly E across the area.
