The Willamette Valley Flood of 1996

Its happening now. What caused it? How does this compare to the big flood of 1964?

Note: This is not a little flood. Its a serious flood for all of Western Washington and Oregon and as of Feb 8 at 2 PM - all rivers are still rising. By any reasonable estimate, this flood will equal that of 1964. It will likely exceed that in many specific locations.

Okay, you weren't kidding!.
