Hazardous marine condition(s):
Gale Warning
ANZ899-210930-
519 PM EDT Sun Sep 20 2026
.SYNOPSIS FOR MID ATLC WATERS...A stationary front extending
off the Carolinas will drift N into tonight. A cold front will
approach from the NW tonight as low pressure tracks E and NE
while passing near or just N of the waters. A trailing cold front
will move S and SE and reach the far northern waters by early
Mon, moving further S over the northern into the central waters
during the day Mon. The front will likely stall from near the
Virginia Capes eastward Mon night through Tue night as low
pressure develops S of the frontal boundary and moves slowly N
and NE. Complex, strengthening, low pressure will move very
slowly N, along or S of the front, Wed through Fri night. Strong
high pressure will build N of the region while interacting with
the frontal boundary and complex low pressure system over the
area to generate strong NE to E gales, and potentially storm
force winds and building seas Tue through Thu night mainly over
the central and northern waters. Mariners are urged to closely
monitor the latest OPC and coastal National Weather Service
forecasts over the coming days, and begin to develop avoidance
plans for this potentially significant weather event.
