Heavy rainfall across eastern Idaho on Thursday has led to the issuance of a flash flood warning by the National Weather Service.

Impact & Risks

The heavy rain and flash flooding pose risks to both residents and infrastructure. Flooding in urban areas, highways, and low-lying regions could disrupt daily activities and transportation.
