The National Weather Service (NWS) in Seattle has issued a weather advisory warning residents of Western Washington of the elevated risks of landslides following substantial rainfall this past week. The affected areas span several counties, including San Juan, Lewis, and Skagit, among others. According to the NWS statement, published on their website, "significant rainfall over the past week has increased soil moisture to high levels across western Washington."
Such conditions have made the ground particularly unstable, raising concerns about potential landslides and debris flows. The NWS cautions that coastal bluffs, steep hillsides, and regions with recent burn scars are especially prone to such events. While precipitation is expected to lighten up over the weekend, a new frontal system approaching Sunday night could unleash heavier rain that might serve as a trigger for more immediate landslide concerns. Already, "numerous landslides have already occurred across the area," says the NWS Seattle.
Meanwhile, the forecast for Seattle remains predictably wet with an 80% chance of showers today and the possibility of continued rain into the week. Temperatures are hovering in the mid-40s with a high near 46°F expected today. Humidity is high at 75% while the current visibility stands at 10 miles, as reported by the NWS's latest weather update.
The ongoing threat may diminish gradually, yet the National Weather Service urges the public to remain on alert, stating that "a diminishing threat of landslides and debris flows will continue for several days after the rain ends." The agency has also directed residents and local authorities to the Washington State Department of Natural Resources for more detailed information on landslide geologic hazards. For those seeking additional current condition updates, NWS recommends visiting their site and heading to the Hydrology section, where links to landslide information pages can be found.
