.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...Strong low pressure
just NW of the outer Washington waters will continue gradually 
weakening tonight into Thu while drifting WNW. Another area of 
low pressure will develop W of the northern California waters Thu,
then rapidly intensify to storm force Thu night and Fri as it 
moves NE across the waters. The low will stall just N of the 
waters Fri night through early Sun as a weak frontal boundary 
develops extending S from the low across the waters. The boundary
will remain stationary through Mon night, with a new weak area 
of low pressure developing along the boundary across the far SW
portion of the outer Oregon waters Mon night.
