Rainfall from the past week has increased soil moisture to high levels across western Washington. Additional rainfall of of one to three inches is expected with the system today into Wednesday morning. This amount of rain will continue to put extra pressure on soil instability, leading to an increased threat of landslides and debris flows, especially from recent burned areas. This rain event could act as a trigger for new landslides. Areas most susceptible to landslides debris flows under these conditions are steep coastal bluffs, other steep hillsides or road cuts, and recent burned areas.

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.
