Significant rainfall over the past week has increased soil moisture to high levels across western Washington. Additional rainfall of 1 to 2 inches is expected through the rest of today. 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, with this new ranfall acting as a trigger. Numerous landslides have already occurred in Whatcom, Skagit, King Counties and others. More landslides are possible. Areas most susceptible to landslides debris flows under these conditions are steep coastal bluffs, other steep hillsides or road cuts, and recent burned areas. A diminishing threat of landslides and debris flows will continue for several days after the rain ends.

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 IN THE PACIFIC NORTHWEST SUMMARY Sporadic severe gusts may accompany low-topped convection across parts of the Pacific Northwest tonight into early Wednesday morning. Pacific Northwest A vigorous shortwave trough will reach coastal WA by late tonight and spread inland through 12Z Wednesday. This trough will be accompanied by an intense tropospheric wind field, characterized by 70-90 kts at 700 mb, that will spread across WA and OR during 06-12Z. A surface cyclone will move onshore in BC and occlude, as downstream lee cyclogenesis occurs over southern AB. Low-topped convection is expected to increase along the trailing cold front attendant to the occluded cyclone, initially reaching coastal WA towards 06Z. Surface-based buoyancy will be scant along the front, but sporadic lightning flashes and occasional strong to severe-caliber wind gusts may accompany the passage of this low-topped convective line. Low-topped convection should also increase ahead of this line overnight, as strong large-scale ascent coincides with peak low to mid-level flow. With minimal instability, low confidence exists in the degree of convective enhancement beyond the gradient winds. Thus, the level 1-MRGL risk has been maintained with no changes.
