Other slides spilled onto Interstate 5 between Olympia and Tacoma and forced the evacuation of a University of Washington fraternity annex in Seattle. High winds cut power to thousands of homes in northern Idaho and some scattered areas in Eastern Washington.

No injuries were reported.

Gus Melonas, a spokesman for Burlington Northern Santa Fe, which owns the railroad tracks, said mud, rocks and trees spilled onto tracks in three places: one a few miles south of Tacoma, and two north of Edmonds, about 15 miles north of Seattle.

Buses were carrying Amtrak passengers around the slides and replaced Sound Transit's Sounder commuter trains between Seattle and Everett. Sounder trains were still rolling between Seattle and Tacoma, said Lee Somerstein, spokesman for Sound Transit, a mass transit agency serving King, Snohomish and Pierce counties.

Melonas said closures affecting passenger rail service would remain in effect at least 48 hours for safety reasons.

The slides did not halt freight trains, which continued running at reduced speeds on parallel tracks north and south of Seattle, Melonas said.

Early last Friday, four slides hit the railroad between Seattle and Everett. Amtrak service resumed Sunday and Sounder trains on Monday.

On Tuesday, state Department of Transportation crews spent the morning clearing debris from a mudslide that blocked a northbound lane on Interstate 5 near the Pierce-Thurston county line. The blocked lane was reopened by late morning.

Heavy snowfall in the mountains prompted temporary lane closures on Interstate-90 over Snoqualmie Pass on Tuesday, as Transportation Department crews did some avalanche control work.

In Western Washington's Kitsap Peninsula, a 2.5-mile section of State Route 166 in Port Orchard remained closed on Tuesday, as geologists tested an unstable slope above the road. It was closed after a mudslide early Saturday.

In Seattle, Tuesday was the 23rd consecutive day of measurable rain. The record, set in 1953, is 33 days. More than 10 inches have fallen since the back-to-back rainy days started Dec. 19.

Since the agency's "weather year" began October 1, Seattle has had just over 19 inches of rain, about 2-1/2 inches above normal and well above the 11 inches in the city at this time last year.

Also in Seattle, a clogged drain was blamed for a mudslide that caused a retaining wall to bulge at a fraternity annex north of the University of Washington. City firefighters evacuated five residents and cut electricity to the building. [ Information on preventing mudslides.]

With more rain in the forecast for the next several days, the National Weather Service issued flood warnings for a handful of Western Washington rivers. Most were expected to crest in the next day or two, with only minor flooding of low-lying areas.

The state Transportation Department reported more than a dozen places around Western Washington where roads have been closed or restricted by mudslides, sinking pavement or water over the roadway. Get information about road closures in King County here.
