.SYNOPSIS FOR THE NORTHERN AND CENTRAL WASHINGTON COASTAL AND INLAND WATERS...A broad surface ridge will rebuild over the coastal and offshore waters through Tuesday. The ridge will then shift east of the Cascades on Wednesday as a splitting front approaches the outer coastal waters. This will turn the flow east to southeasterly midweek. Broad surface ridging rebuilds late in the week before another weak front approaches the waters over the weekend.
