Boise, Idaho – Residents across southwest Idaho and eastern Oregon are at risk of dangerous flash flooding on Saturday afternoon, as heavy rain targets wildfire burn scar areas. The National Weather Service in Boise has issued a Flash Flood Watch from midday through Saturday evening, warning that localized debris flows are possible.
The Flash Flood Watch covers Idaho’s West Central Mountains, Lower Treasure Valley, and Upper Weiser River region, as well as Oregon’s Harney, Baker, and Malheur counties. Cities at risk include McCall, Cascade, Nampa, Ontario, Burns, and Baker City. Rainfall rates may intensify enough to overwhelm drainage systems, particularly in areas recently impacted by wildfires.
Travelers are advised to avoid driving across flooded roads and remain alert for sudden road closures. Authorities recommend residents in vulnerable areas prepare evacuation plans, charge electronic devices, and move valuables to higher ground before the storms arrive.
The heaviest rain is expected between 2 p.m. and 9 p.m. Saturday, with rapid runoff likely into creeks, streams, and low-lying areas. If conditions worsen, additional Flash Flood Warnings may be issued.
