Spokane, WA – Another round of heavy rain is expected to bring an increased risk of rockslides and mudslides across parts of Washington and northern Idaho from Monday through Wednesday, according to forecasters.
According to the National Weather Service in Spokane, already saturated ground from recent storms combined with incoming rainfall will heighten the threat in steep terrain and near burn scar areas, particularly along the Cascade Mountains and the Central Idaho Panhandle Mountains.
Forecasters expect 1 to 5 inches of rain in Chelan County, with 1 to 2.5 inches possible across the Central Panhandle Mountains during the 72-hour period. Even brief periods of heavier rain could trigger slope failures, especially in vulnerable areas.
The NWS warns of the potential for mudslides and rockslides, which could impact mountain roads, recreation areas, and nearby communities. Rivers and creeks may also rise, increasing the risk of localized flooding in low-lying and downstream areas.
Drivers traveling through mountain passes, canyon roads, and forested areas are urged to remain alert for falling rocks, debris on roadways, and sudden closures. Conditions may deteriorate quickly during heavy rain, particularly overnight.
Residents living near steep hillsides or recent wildfire burn scars should stay weather-aware and be prepared to move to safer ground if conditions worsen. Officials emphasize that landslides can occur with little warning.
The NWS recommends monitoring forecast updates closely through midweek as rainfall totals and impact zones may change.
