Where: Lincoln, Sanders, and Mineral counties in Montana. Clearwater and Idaho counties in Idaho. When: Monday and Tuesday early next week. What: An Atmospheric River is expected to bring high amounts of moisture resulting in moderate to heavy rainfall to areas of western Montana and north-central Idaho early next week. The Clearwater Mountains in north-central Idaho currently have around a 60% probability of receiving at least 1" of rainfall in a 24hr period from Monday to Tuesday. These probabilities are much lower for western Montana, around 20-30%. High elevation snowmelt coupled with high surface moisture, along with expected rainfall, will increase the risk for minor impacts due to rock and mudslides. Area small streams and creeks will also see a noticeable rise in water levels. Continue to monitor the forecast for updates as we progress through the weekend. $$
