.SYNOPSIS FOR MID ATLC WATERS...A stationary front will persist
from near the South Carolina coast east and northeastward tonight
as a series of developing low pressure centers move NE along the
front. The final low will pull an associated cold front E over
the southern waters early Mon as another front approaches the N
waters and weakens. The final low will intensify over the outer
portion of the southern and central waters later Mon into Mon
night, with the intense low passing E of the central and northern
waters Tue into Tue night. All mariners should monitor the latest
forecast and progress of this strengthening low, and excute
avoidance plans as necessary. Widespread thunderstorms are likely
near the front and low mainly over the southern and central
waters through tonight into Mon. Very gusty winds and rough seas
are possible in the stronger tstms and mariners should use
caution. The intense low will move NE away from the region Wed as
the next cold front begins to move just off the New Jersey and
Delmarva coasts. The front will move SE over the northern and
central waters Wed night into Thu, and the S waters Thu night.
High pressure will build SE into the region Fri and Fri night.
