.SYNOPSIS FOR NEW ENGLAND WATERS...A broad and complex coastal
low will persist today. One low center will remain nearly
stationary near the mouth of the Delaware Bay today. A trough
extends south from that center to a second low center well S of
the waters. The northern center will dissipate just inland
tonight into Tue as a new center forms over the outer Mid-
Atlantic waters. Mariners should continue to monitor later
forecasts on this coastal system as it will be highly impactful
to the mariner through the middle of the week. The entire complex
low will drift SE away from the waters Tue night through Wed
night. High pressure will build S into the eastern U.S. Wed
through Fri. On Thu, the broad low, still well E of the waters,
will drift back W, leading to a strengthening pressure gradient
across the waters. The low will finally move E away from the area
Fri night as high pressure builds E offshore into the Mid-
Atlantic waters.
