NAVTEX Marine Forecast for Mid-Atlantic states waters

NWS Ocean Prediction Center Washington DC

521 PM EDT Sun Sep 20 2026



Conditions given represent the highest within that period.



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



...Please refer to Coastal Waters Forecasts (CWF) available

through NOAA Weather Radio and other means for detailed coastal

waters forecasts...



.SYNOPSIS...A stationary front extending off the Carolinas will

drift N into tonight. A cold front will approach from the NW

tonight as low pressure tracks E and NE while passing near or

just N of the waters. A trailing cold front will move S and SE

and reach the far northern waters by early Mon, moving further S

over the northern into the central waters during the day Mon. The

front will likely stall from near the Virginia Capes eastward Mon

night 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 Thu night mainly over the central and northern waters.

Mariners are urged to closely monitor the latest OPC and coastal

National Weather Service forecasts over the coming days, and

begin to develop avoidance plans for this potentially significant

weather event.
