Risk Overview

About Natural Disaster Risk in Cass County, Nebraska

Cass County faces slightly elevated risk

With a composite score of 31.04, Cass County carries Very Low risk overall but registers above the national average. The county's hazard profile reflects a combination of managed but notable natural disaster exposures.

Slightly above Nebraska's average risk

Cass County's 31.04 score exceeds Nebraska's state average of 25.80 by about 20 percent, positioning it as one of the state's moderately exposed counties. The county ranks in the middle-to-upper tier of Nebraska's risk spectrum.

Higher risk than most nearby counties

Cass County's 31.04 score exceeds Burt County (20.67), Butler County (24.46), and Cedar County (21.69), indicating notably more hazard exposure than surrounding communities. Only Buffalo County (66.00) in the broader region carries significantly higher composite risk.

Tornado risk leads Cass County concerns

Tornado risk (63.10) is Cass County's most significant hazard, substantially above state averages and demanding active preparedness. Wildfire (74.14) and flood (36.96) risks round out a triplet of moderate-to-elevated threats.

Multi-hazard coverage strongly recommended

Cass County residents should secure comprehensive homeowners insurance that explicitly covers wind, tornado, flood, and wildfire damage. Investing in storm-resistant improvements and maintaining an updated disaster preparedness plan is prudent given the county's elevated tornado exposure.

Risk Verdict

Cass County sits in the lower tier of U.S. counties for natural disaster exposure, ranked at the 31th percentile nationally. A 31th percentile score positions Cass County among the nation's lower-risk counties, a genuinely favorable outcome — one that simple, low-cost preparedness habits can reinforce further.

Wildfire risk is Cass County's dominant natural hazard, ranked at the 74th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 63th percentile nationally. Additional tracked hazards include flood (37th percentile), earthquake (12th percentile), hurricane (0th percentile).

Preparedness Context

At the 74th percentile nationally for wildfire risk, Cass County households benefit from creating defensible space — a buffer of reduced vegetation around structures — and reviewing whether homeowners insurance covers wildfire damage in this region. A secondary tornado exposure at the 63th percentile nationally means Cass County residents face hazards from two distinct natural peril categories during different seasons. Enrolling in the county's wireless emergency alert system and keeping a vehicle at least half-full during peak fire season are low-cost habits that dramatically reduce evacuation lag time for Cass County residents.

Regional Context

At 5.2 points above the Nebraska state average, Cass County carries meaningfully higher natural disaster exposure than a typical Nebraska county.

The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Cass County higher risk than average?
Cass County's composite risk score of 31th percentile is above the Nebraska state average of 26th percentile.
