from 1000 fm to 250 nm offshore.

.SYNOPSIS FOR MID ATLC WATERS...A stationary front will persist
from the South Carolina coast eastward tonight, and then drift N 
Sun into Sun night. Low pressure located along the front over 
the outer waters will weaken later tonight, then move N and NE 
Sun into Sun night. A cold front will reach the far northern
waters late Sun night, and then slowly move S 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. Low pressure or a wave of low pressures will 
move very slowly N along or S of the front Wed through Thu 
night. Strong high pressure will build N of the region while 
interacting with the frontal boundary and low pressure over the 
area to generate NE to E gales, and potentially storm force 
winds and building seas late 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 event.
