.SYNOPSIS FOR NEW ENGLAND WATERS...A warm front will develop and
lift N over the Gulf of Maine this evening. A strong cold front
will move quickly E and SE across the waters tonight, and move
well E and S of the area Mon. High pressure will build E across
the area late Mon, persist Mon night, and then move quickly off
to the E early Tue. Intensifying low pressure will approach the
waters from the SW early Tue and move into the area late Tue into
Tue night. The low will rapidly exit NE of the region Wed before
high pressure quickly moves across the waters late Wed into Wed
night. Yet another strong cold front will move SE across the
area Thu before exiting to the E and SE Thu night. Mariners
should monitor the latest forecasts for the intensifying low
pressure system set to impact the region Tue into Wed, and begin
to strongly consider avoidance routing at this time.
