* WHAT...Flooding caused by excessive rainfall remains possible. * WHERE...Portions of northwest Oregon and southwest Washington, including the following counties: in Oregon, Benton, Clackamas, Clatsop, Columbia, Hood River, Lane, Lincoln, Linn, Marion, Multnomah, Polk, Tillamook, Washington, and Yamhill. In Washington, Clark, Cowlitz, Pacific, Skamania, and Wahkiakum. * WHEN...Through late Tuesday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations, especially for rivers draining the Willapa Hills and Oregon Coast Range. Flooding may occur in poor drainage and urban areas. Landslides are possible through this period, especially over the Cascades due to heavy rainfall above 7,000 feet combined with snowmelt. There is low probability for debris flows as rainfall rates are not expected to meet thresholds over recently burned areas. * ADDITIONAL DETAILS... - An atmospheric river and series of frontal systems will produce periods of heavy rainfall over northwest Oregon and Southwest Washington through Monday. The heaviest rain will be over the coast, Coast Range, Willapa Hills, and Cascades where rain totals through Monday night will range from 4 to 6 inches, with locally higher amounts possible. Snow levels will rise to above 7,000 feet on Sunday, and snow melt due to rain falling on the Cascade snow pack could cause additional flooding concerns for drainages from the Cascades along with enhanced risk of landslides. - http://www.weather.gov/safety/flood
