* WHAT...River and urban flooding caused by excessive rainfall is possible. Landslides possible in areas of steep terrain, and debris flows possible over recently burned areas. * WHERE...Counties in Oregon: Benton, Clackamas, Clatsop, Columbia, Hood River, Lane, Lincoln, Linn, Marion, Multnomah, Polk, Tillamook, Washington, and Yamhill. Counties in Washington: Clark, Cowlitz, Pacific, Skamania, and Wahkiakum. * WHEN...From late tonight through late Thursday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Landslides and debris flows are possible during this flood event. People, structures, and roads located below steep slopes, in canyons, and near the mouths of canyons may be at serious risk from rapidly moving landslides. * ADDITIONAL DETAILS... - A prolonged atmospheric river is expected to bring periods of heavy rain to northwest Oregon and southwest Washington Monday through Wednesday, with periods of lighter rain continuing Thursday into Friday. Rivers draining the coastal mountains and several Willamette Tributaries have the highest chance of flooding at 40 to 80%. Chances for flooding along the Willamette mainstem remains low at less than 10%. Urban flooding is possible and water on roadways will increase the risk of hydroplaning. Landslides in areas of steep terrain will be possible, as well as debris flows over recently burned areas. - http://www.weather.gov/safety/flood
