Risk Overview

About Natural Disaster Risk in Audubon County, Iowa

Audubon: Low Risk, Moderate Preparedness

Audubon County's composite score of 38.58 falls just below Iowa's state average of 39.68, earning a Very Low rating. This modest but manageable risk profile places Audubon among Iowa's safer communities, though still above the nation's lowest-hazard zones.

Below-Average Risk Across Iowa

Audubon ranks in the safer half of Iowa's county distribution, with risk exposure consistently moderate to low across most hazard categories. The county benefits from relatively stable terrain and distance from major river systems that plague other regions.

Safer Than Most Neighbors

Audubon's 38.58 score slightly trails neighboring Adair at 49.49 to the east, but substantially beats Appanoose to the south at 41.19. Adams County to the southwest remains the region's safest outlier at 20.36.

Tornadoes Lead, Wildfires Secondary

Tornado risk at 59.67 is Audubon's primary concern and above the state average, while wildfire exposure of 33.37 ranks moderate. Flood risk remains low at 19.78, making tornado preparedness the core planning priority for residents.

Tornado Coverage and Safe Planning

Audubon residents should ensure wind and hail insurance covers tornado damage and maintain an accessible safe room or shelter plan. Annual preparedness drills and weather radio monitoring provide low-cost protection against the county's signature storm threat.

Risk Advisory: Audubon County

Risk Verdict

Compared to the nation's 3,144 counties, Audubon County ranks at the 39th percentile for natural disaster risk — toward the safer end of the spectrum. At the 39th percentile nationally, Audubon County's natural hazard profile is comparatively favorable — community resilience is reinforced when individual households maintain a reviewed emergency plan.

Hazard Breakdown

Tornado risk is Audubon County's dominant natural hazard, ranked at the 60th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 33th percentile nationally. Additional tracked hazards include flood (20th percentile), hurricane (15th percentile), earthquake (7th percentile).

Preparedness Context

Tornado exposure at the 60th percentile nationally makes Audubon County a county where a battery-powered weather radio — not just smartphone apps — is a worthwhile household investment, given that mobile networks often fail during severe storms. Alongside tornado exposure, wildfire at the 33th percentile nationally means Audubon County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. In Audubon County, tornado watches indicate favorable atmospheric conditions while warnings mean rotation has been detected — households benefit from understanding this distinction so they shelter immediately on a warning, not after seeking visual confirmation.

Regional Context

Audubon County sits within 1.1 composite points of the Iowa state average, suggesting the county's hazard exposure is representative of the broader regional pattern.
