Natural Hazard Profile: Corunna, Michigan

Located in the Great Lakes region in Shiawassee County, Corunna is a town of roughly 5,416 residents. The humid continental climate that characterizes this part of Michigan — marked by severe winters amplified by lake-effect snow and warm, humid summers — directly influences the types and severity of natural hazards present, making Corunna a community where hazard awareness has real practical value.

FEMA rates Corunna's composite natural disaster risk at 5.5 out of 10 — moderate risk. High-wind events from severe thunderstorms and derechos are the leading hazard, with damaging gusts capable of downing trees and causing widespread structural damage.

Relative to other U.S. communities, Corunna's natural disaster risk is above the U.S. national average of 4.5/10, near the 5.3/10 state average. The hazard distribution here is led by wind and tornado, as measured by FEMA across Shiawassee County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Corunna residents are well-served by maintaining standard preparedness practices — an emergency supply kit, awareness of local hazard seasonality, and insurance that covers the top local risks. Periodic review of coverage for wind is recommended.
