Hazardous marine condition(s):
Gale Warning
ANZ899-230815-
502 PM EDT Tue Sep 22 2026
.SYNOPSIS FOR MID ATLC WATERS...A stationary front persists across
the central portions tonight, generally extending E and NE from
near Nags Head, North Carolina, while a low pressure continues to
track NE across the S portions well E of Hatteras Canyon.
Meanwhile, a strong high pressure continues to build S from New
England across the northern portions, and will shift to the E
later Wed and Wed night. Low pressure develops along the
stationary boundary late tonight into Wed, then drifts NE of the
Mid-Atlantic waters Wed night into Thu while pulling a cold
front through the southern waters. The low intensifies and
broadens Wed night into Thu, then begins to drift to the NW Thu
night into Fri. Strong counterflow to the Gulf Stream will
create large, very steep, and possibly breaking waves resulting
in a particularly hazardous sea state. The low remains quasi-
stationary N of the area Fri night through Sun night, while high
pressure builds SE across central and S portions. Mariners should
continue monitoring forecasts for the low pressure, and consider
avoidance plans as needed. This will be a long duration event,
impactful to the mariner.
