The front will likely stall over the far S waters later Mon into Mon night as high pressure builds in across the N and central waters. Low pressure will develop along the stationary front just inland over Georgia and S Carolina Mon night, with the low intensifying while lifting NE from near the Outer Banks Tue to near Georges Bank Tue night. A cold front extending S from the low will move quickly E and SE across the waters late Tue into Tue night. High pressure will build over the waters Wed, persist Wed night, and then weaken early Thu. Yet another cold front will move SE over the N and central portions late Thu before stalling across the far S waters Thu night. High pressure will build E over the N waters Fri into Fri night. The front and developing low pressure will begin to move back to the N over the S and central waters late Fri into Fri night. Mariners should monitor the latest forecasts for the intensifying low pressure system set to impact the region Mon night into Wed, and begin to strongly consider avoidance routing at this time.
