Heavy rain and snowmelt has caused widespread flooding across the region.

The good news is a Flood Warning for Northwest Oregon and Southwest Washington expired Tuesday afternoon. But 2 to 5 inches of rain has fallen over that area in the last 24 hours, the National Weather Service said.

Portions of Highway 30 in St. Helens and Scappoose were covered with water. Sky 8 showed most drivers ignored the water and drove through it. 

Multnomah County closed NW Rocky Point Road between Highway 30 and NW Skyline Boulevard after a large crack was spotted in the pavement about a mile-and-a-half away from the highway. Officials are concerned about a possible slide.
