In Washington State - Clark, Cowlitz, Pacific, Skamania, Wahkiakum. * WHEN...From late Wednesday night through late Friday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Area creeks and streams are running high and could flood with more heavy rain. 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... - An atmospheric river is forecast to bring periods of heavy rain to northwestern Oregon and southwestern Washington at a time when area rivers continue to run high and soils remain saturated following heavy rain earlier in the month. During initial heavy rainfall on Thursday, the urban and small stream flooding threat will be most urgent, although the details of precise timing and location of the highest risk remains uncertain at this time. As runoff works its way downstream, the river flooding threat will increase Thursday night into Friday, with numerous area rivers now forecast to reach at least Minor flood stage. - http://www.weather.gov/safety/flood PRECAUTIONARY/PREPAREDNESS ACTIONS... You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. &&

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE PACIFIC NORTHWEST SUMMARY Sporadic severe wind gusts may accompany isolated thunderstorms across parts of the Pacific Northwest tonight. Pacific Northwest A vigorous lead shortwave trough will steadily amplify today and reach the coastal Pacific Northwest tonight. This will be accompanied by a strong deep-layer wind field, highlighted by 90+ kt winds at 500 mb and 50-80 kt winds within the lowest 1-3 km AGL. This will be as Pacific moisture also steadily increases tonight in tandem with the inland-advancing cold front. Low-topped convection is expected to accompany the front, initially approaching the Washington coast by late evening, and then more interior areas overnight/early Wednesday. Surface-based buoyancy will remain meager, but very strong gradient winds will shift from the southwest to west-northwest as the front passes. Sporadic lightning flashes and strong to severe-caliber wind gusts may accompany the passage of this low-topped convective line, with the most intense low-level winds/convective influences expected to peak during the overnight and early morning hours of Wednesday.
