SYNOPSIS FOR SOUTHEAST ALASKA INNER CHANNELS COASTAL WATERS

High pressure in the Gulf will linger through the end of the week into the weekend. Winds moderate to fresh for the outer coastal waters and N-S oriented channels will diminish into the weekend. Localized wind shifts due to sea breezes possible, but overall wind pattern is expected to be N to NW. Seas 5 to 7 feet in outer coastal waters will trend downward by the weekend.

A Marine Weather Statement continues for Stephens Passage due to trees and other debris in the waters due to the ongoing Mendenhall River flood.
