PORTLAND (AP) — Rains, melting snow and high tides combined to close U.S. 101 at Tillamook and restrict traffic at Seaside on Thursday, but the drenching Western Oregon has taken in recent days is easing off.

Partly cloudy weather is expected over much of Oregon through Monday.

Adam Torgerson, northwest Oregon spokesman for the Oregon Department of Transportation, said U.S. 101 south of Seaside was open only to high-center and emergency vehicles while it was closed at Tillamook, but that a short detour was open.

Flood warnings for parts of Union County in the east are posted today. Some valley flooding was reported in the Union, Elgin and La Grande areas.

Washington took the brunt of the Thursday night storm. Floods, mudslides and avalanches stopped trains and kept thousands of people in their homes.

A 20-mile stretch of Interstate 5 was shut down between Olympia and the Oregon line, with one section under 3 feet of water. Because of the closed highways, a truck traveling from Portland to Seattle, normally about 175 miles, needed a 440-mile detour. Ten thousand trucks travel I-5 each day.

None of the 60 or so freight and passenger trains that usually travel between Portland and Seattle each day was moving. Some freight was being rerouted.
