.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure will continue to
build over the area today through tonight. The high will
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. Mariners should monitor later forecasts
on the coastal system. This will be a long duration event for the
east coast, impactful to the mariner.
