Natural Disaster Risk in Union

Natural Hazard Profile: Union, Iowa

Located in the interior eastern United States in Hardin County, Union is a small community of about 958. The humid continental climate that characterizes this part of Iowa — marked by cold winters, hot summers, and frequent severe weather — directly influences the types and severity of natural hazards present, making Union a community where hazard awareness has real practical value.

Union's overall natural disaster risk is rated 5.6/10 (Moderate) by FEMA's National Risk Index. Hail is the primary natural disaster concern, with severe storms delivering baseball-sized or larger hailstones that cause significant insured losses each year. Secondary hazards include drought and tornado.

Relative to other U.S. communities, Union's natural disaster risk is above the U.S. national average of 4.5/10, near the 5.4/10 state average. The hazard distribution here is led by hail and drought, as measured by FEMA across Hardin County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Union's moderate risk profile means that while catastrophic events are less frequent, they do occur. Standard homeowners insurance typically covers many common hazards here, but confirming that hail exposure is adequately protected is a worthwhile step for property owners.
