A major storm system is forecast to bring heavy rainfall and isolated thunderstorms to the region, posing significant risks of mudslides and debris flows in areas recently scorched by wildfires.
Brace for Impact: Burned Areas at High Risk for Rapid Mudslides
BOISE — Issued by the National Weather Service at 2:50 PM MDT on September 15, 2024.
Widespread Rain Expected Monday and Tuesday
The National Weather Service in Boise, Idaho, has issued a hydrologic outlook warning of widespread precipitation across the region on Monday and Tuesday. The forecast predicts showers will intensify and become more frequent, accompanied by isolated thunderstorms that could bring moderate to heavy rain. The areas of greatest concern include those recently affected by wildfires, where intense rainfall can trigger dangerous mudslides and debris flows.
High-Risk Areas: Wildfire Zones on Alert
Particularly at risk are locations like State Highway 21 in the Wapiti Fire area, where the soil’s integrity has been compromised by recent burns. The sudden downpours expected from these thunderstorms can cause the already weakened ground to give way, resulting in fast-moving mudslides that can occur with little to no warning.
