(Portland, OR)  --  Officials say conditions are right for more landslides in the Portland Metro in the coming days.  About one-thousand feet of debris collapsed onto Northwest Old Cornelius Pass Road in Hillsboro yesterday morning.  The Portland Bureau of Transportation says crews reopened Southwest Skyline several days after a landslide sent 900 tons of debris into the roadway.  Ali Ryan Hansen, spokesperson with the Oregon Department of Geology and Mineral Industries, tells KATU-TV all of Western Oregon could be at risk, not just the Portland Metro.
