The moisture from this storm system will help two fast-moving winter storms spread snow across the eastern U.S., with another atmospheric river on its way.

The "Godzilla atmospheric river" system may bring major flooding, landslide dangers, and a month's worth of rain compressed into just days.

More than 10 inches of rain has fallen in parts of Washington this week as a strong atmospheric river hits the state.

And with mudslides closing down eastbound I-90, traffic is being redirected through North Bend, adding even more traffic concerns as roads are closed and flooding. Leonard said the conditions were a surprise to him Thursday morning, especially when he first hit the road.

At least 100,000 residents are under evacuation warnings as more than a foot of rain triggers historic river flooding.
