...STORM WARNING THROUGH THIS EVENING...

Synopsis: As of 1pm Tuesday a storm force low is developing near fifty two north, one forty three west, quickly moving north into the Gulf of Alaska. This low is expected to reach the Fairweather grounds by 1 am Wednesday. Most concerning is the broad fetch of southerly storm force winds on the eastern flank of this storm, generating 35 ft seas. For the inner channels of Southeast Alaska, winds will continue to increase through Tuesday evening. Mariners should make ready for southeasterly gale force winds, with storm force in some larger passages.
