.SYNOPSIS FOR NEW ENGLAND WATERS...Strong high pressure centered
N of the area will drift off to the NW into Sat night, and the
slowly shift E early next week. Intensifying low pressure
centered about 200 nm E to NE of Cape Hatteras will track slowly
to the N and NW today into Sat night while approaching western
Long Island or New Jersey Sat night, slow and turn to the SW and
S while weakening Sun, and then gradually turn more towards the E
Sun night while passing just S of the waters. The weakening low
is forecast to move NE over the region Mon into Mon night, and
gradually pass E of the waters Tue and Tue night as high pressure
builds E towards the coast. Mariners should continue monitoring
forecasts, and consider avoidance plans as needed. This will be a
long duration event, and highly impactful to the mariner into
the weekend.
