.SYNOPSIS FOR MID ATLC WATERS...A broad and complex coastal low
pressure with the main center just to the east of Ocean City will
remain nearly stationary today, then dissipate later tonight. A
second low centered just SE of Cape Fear will move E across the
southern waters today, then dissipate tonight. A new low center
will re-develop across the outer mid-Atlantic waters early Tue,
with the entire complex low system drifting E and SE away from
the area Tue night through Wed night. 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.
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,
particularly over the outer northern waters. The low will finally
move E away from the area Fri night as high pressure builds E
offshore into the waters.
