183 FZNT34 KWBC 101448 OFFN32 Marine Weather HF Voice Broadcast NWS Ocean Prediction Center Washington DC 1048 AM EDT Fri Oct 10 2025 West central North Atlantic continental shelf and slope waters beyond 20 nm to 250 nm offshore, including south of Georges Bank from 1000 fm to 250 nm offshore. 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 MID ATLC WATERS...A cold front will stall over the far S waters today and tonight. High pressure will move offshore from New England to near Georges Bank by late today, resulting in counterflow to the Gulf Stream and the potential for steeper, breaking waves. The high will then shift NE of the area tonight and Sat. To the S, low pressure will form offshore of the E Florida coast along the stalled front later today. The low will deepen and expand as it moves N tonight through Sun, eventually being centered just offshore of the Virginia Capes Sun night. This broad, complex low will move very slowly E from the Virginia Capes to the outer Mid-Atlantic Waters Sun night through Tue night. Mariners must monitor later forecasts on the coastal system, and begin to consider avoidance plans as needed. This will be a long duration event for the east coast, impactful to the mariner.
