The answer to why salmon crossed the road in Washington state Tuesday morning may be simple: because of major flooding on the roadway, caused by heavy rain and seemingly confusing the heck out of the migrating fish (see video).

A powerful storm system arrived along parts of the Pacific Northwest on Tuesday, including Western Washington, kicking off what promises to be a wet and windy Thanksgiving holiday week.

Rainfall totals should reach three inches in the Seattle area before Thanksgiving Day. Wind gusts from 50-70 mph were recorded in some areas.

The video, posted on the KOMO News website, shows salmon swimming across flooded Skokomish Valley Road in Mason County. The road is near Shelton, the westernmost city on Puget Sound, with its many meandering waterways. Hopefully the salmon, if more find their way onto area roads, will be able to avoid the busy holiday traffic.
