from 1000 fm to 250 nm offshore.

Conditions given represent the highest within that period.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be

.SYNOPSIS FOR MID ATLC 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 SE of Cape Fear. The
southern low center will move quickly E across the southern
waters today and tonight, while the northern center dissipates
just inland later tonight into Tue. Later on Tue, a new low
center will form 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, 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.
