with the trailing cold front stalling over the far S waters. The
National Hurricane Center is monitoring the low for any signs of
sub-tropical or tropical cyclone development, and mariners should
monitor the latest forecast and information from the National
Hurricane Center. Also, all mariners should use caution in or
near any of the heavier thunderstorms which will likely persist
mainly near and S of the front and low pressure area today into

the W wall of the gulf stream where very gusty winds and very
rough seas will be likely today. Otherwise, The front will linger
over the far S waters Mon night through Thu night with weak lows
occasionally forming along the frontal boundary. High pressure
over the far N waters will prevail for the next few days, with a
stronger high expected to build N of the area Tue night into Thu
