(Portland, OR) -- It was 30 years ago that heavy snow fell on the Pacific Northwest and then a pineapple express from the tropics poured into the region. The storms brought 15 inches of rain melting the snow and through February 8th turned streams into raging rivers. Mudslides covered roads and isolated towns. Dairy cows drowned in fields. The City of Portland set up an extension to the seawall to keep the Willamette River from flooding the downtown.
