SOUTHEAST U.S. WATERS

SYNOPSIS...Low pressure off the SE U.S. coast will deepen and expand as it moves N tonight into Sun, with a secondary low forming and eventually being centered 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, before clearing well E into the Atlantic Wed and Wed night. Mariners should monitor later forecasts on the coastal system, and consider avoidance plans as needed. This will be a long duration event for the east coast, and impactful to the mariner. A weak low pressure trough or cold front will pass SE across the area Tue and Tue night. Another cold front will approach from the NW late Tue into Tue night, and move SE across the waters Wed and Wed night. High pressure will build in across the region Thu and Thu night.
