Some of you have noted the tendency for coastal acceleration..and this does occur--in fact I just finished a paper on coastal windstorms where I talk about this effect. The interaction of onshore flow with the coastal terrain produces the speed up.
The Portland NWS has now put up a storm watch for the Oregon coastal waters. From their statement:
A STORM WATCH IS ISSUED WHEN THE RISK OF STORM FORCE WINDS OF
