.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure remains over the
waters tonight as strengthening low pressure meanders off of the
SE U.S. coast. The high moves E tonight and Mon as the broad low
slowly moves N toward the mid-Atlantic. Then, for Mon night
through Wed night, the waters will be between the strong low
stalling then offshore of the mid-Atlantic coast, and high
pressure over the Great Lakes and SE Canada. A cold front
approaches the area from the NW Thu, moving into the waters Thu
night and through the area Fri. High pressure should build in
from the NW Fri night. Mariners should monitor the latest high
seas, offshore, coastal, and tropical forecasts on the low
pressure system, executing avoidance as needed for any voyages
planned especially to the south of the area.
