Landslide risk high, state asks public's help

Dec 13, 2010

The heavy rains dumped by the Pineapple Express have caused so many landslides, the state is asking your help in keeping track of them. 

The National Weather Service reports 29 major landslides since Friday. 

Washington's Department of Natural Resources reports the slides have damaged roads, houses, and power lines across western Washington, and portions of the Burke-Gilman trail in Seattle. 

State geologists at DNR keep a landslide database and current statewide landslide map, and say any help you can provide will help their effort to create a landslide forecast system.

The DNR website explains how to safely document and report a slide.

Some of the largest slides blocked roads and rail lines. Seattle crews cleared 25 trees  brought down by a mudslide early Monday morning alongside West Marginal Way in the city's south end, according to the West Seattle Blog. The slide closed the busy road for hours.

Amtrak Cascades and Sounder commuter rail services were canceled because of mudslides between Everett and Seattle. Those agencies are working to have the lines open again by the Tuesday commute.

The Weather Service has issued a warning that the landslide risk remains high for the next few days -- due to the cumulative rainfall over the past three weeks.
