.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure will continue to
build over the area tonight through Fri night. 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 mid-Atlantic coast
by Sun night. The broad, complex low will extend over much of the
east coast Sun night and Mon, with the broad low finally
starting to shift E Mon 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.
