.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure will continue to
build over the area tonight, then gradually shift NE Sat through
Sun as a coastal low moves N just offshore of the SE U.S. The
low will strengthen and expand as it moves N, being centered just
offshore of the Virginia Capes by Sun night. This broad, complex
low will move very slowly E from the Virginia Capes across the
outer Mid-Atlantic Waters Sun night through Tue night, then
finally move E of the area Wed. Mariners should monitor later
forecasts on the coastal system. This will be a long duration
event for the east coast, impactful to the mariner. A cold front
will approach from the NW Wed, then move offshore Wed night.
