.SYNOPSIS FOR NEW ENGLAND WATERS...Low pressure will move E
across the far S waters today. An associated front will stall and
low pressure is expected to redevelop near or S of the front
tonight through Tue night. It will lift slowly N towards the
waters Wed and Wed night. Strong high pressure will build N of
the region Tue and Tue night, then continue Wed into Thu night.
The low will strengthen just S of the region Thu and Thu night,
then move into the N waters Fri and Fri night. Widespread strong
gale force winds, with storm force wind gusts, and building seas
are likely over most of the waters beginning Tue and continuing
through Fri night. Mariners should consider avoidance plans as
this significant weather system likely impacts most of the region
Tue through Thu night. Please monitor the latest OPC and coastal
marine forecasts.

Offshore Waters Forecast
NWS Ocean Prediction Center Washington DC
513 AM EDT Mon Sep 21 2026
West central North Atlantic continental shelf and slope waters
beyond 60 nm to 250 nm offshore, including south of Georges Bank
from 1000 fm to 250 nm offshore.
Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be

ANZ899-211945-
513 AM EDT Mon Sep 21 2026
.SYNOPSIS FOR MID ATLC WATERS...A cold front will move S and SE
over the far northern waters this morning, moving farther S over
the northern into the central waters today. The front will stall
from near the Virginia Capes eastward tonight through Tue night
as low pressure develops S of the frontal boundary and moves
slowly N and NE. Complex, strengthening, low pressure will move
very slowly N, along or S of the front, Wed through Fri night.
Strong high pressure will build N of the region while interacting
with the frontal boundary and complex low pressure system over
the area to generate strong NE to E gales, and potentially storm
force winds and building seas Tue through Fri night mainly over
the central and northern waters. Mariners should consider
avoidance plans as this significant weather system likely impacts
most of the region Tue through Thu night. Please monitor the
latest OPC and coastal marine forecasts.
