FYI, according to your link: "The difference between hurricane and typhoon is that tropical cyclones in the west Pacific are called Typhoons and those in the Atlantic and east Pacific Ocean are called Hurricanes." Last I checked, Oregon is in the east Pacific, so the tropical cyclone would (indeed) be called a hurricane, yes?

If a tropical cyclone hit Oregon it would probably have started as a hurricane, not a tornado. Typhoons form west of the International Date Line, and they move predominantly west. Typhoons are pretty much guaranteed to never move east across the IDL, because of the prevailing winds.

I think you got confused about the "NE Pacific Ocean" thing under the Hurricane column. The NE Pacific Ocean is the part of the Pacific Ocean that Oregon is on.

It would technically be an extratropical cyclone, but it would likely have started as a tropical hurricane off the coast of Mexico.
