Boise, Idaho – Residents across southwest Idaho and eastern Oregon are under a Flash Flood Watch through early Monday morning as heavy overnight rain raises the threat of flooding and debris flows, especially in wildfire burn scar areas.
According to the National Weather Service in Boise, the watch remains in effect until 3 a.m. MDT Monday for Idaho’s West Central Mountains, Owyhee Mountains, Upper Weiser River region, and Lower Treasure Valley, along with Oregon’s Baker, Harney, and Malheur counties. Meteorologists warn that intense rainfall could overwhelm dry terrain, triggering sudden flooding and landslides.
Communities including McCall, Cascade, Ontario, Burns, Baker City, and Nampa are urged to stay alert as storms continue to move across the region. Officials note that burn scar areas, particularly near recent wildfires, are at the highest risk for fast-moving water and debris flows that can damage roads and homes.
Drivers are advised to avoid low-lying roadways and canyon routes overnight, where conditions could change rapidly. Emergency officials recommend keeping cell phones charged and monitoring alerts in case additional warnings are issued before dawn.
The Flash Flood Watch is expected to expire early Monday, but forecasters say unsettled weather could return later this week.
