Risk Overview

About Natural Disaster Risk in Custer County, Nebraska

Custer County's Very Low Risk Rating

Custer County has a composite risk score of 27.99 and a Very Low rating, placing it near the national average for natural disaster exposure. However, wildfire (82.32) and tornado (50.32) risks are notably elevated despite the overall low composite score.

Below-Average Risk in Nebraska

At 27.99, Custer County ranks slightly above Nebraska's state average of 25.80, positioning it among the state's safer counties overall. The county's composite score masks significant regional wildfire exposure that warrants attention.

Mixed Hazard Profile Regionally

Custer County (27.99) is safer overall than Cuming County (57.28) but faces higher wildfire risk (82.32) than most regional neighbors. Its tornado risk (50.32) is moderate compared to surrounding counties, providing some relative protection against severe convective weather.

Wildfire and Tornado Primary Concerns

Wildfire risk dominates Custer County with a score of 82.32—among the state's highest—while tornado risk (50.32) presents secondary exposure. Flood risk remains manageable at 43.48, allowing residents to concentrate preparation on fire and wind events.

Prioritize Fire and Storm Insurance

Custer County residents should prioritize comprehensive fire and windstorm insurance given the county's extreme wildfire exposure. Maintaining defensible space around your home—removing dead vegetation and dead trees—is critical, particularly in grassland and prairie areas.

Risk Advisory: Custer County

Risk Verdict

Custer County's overall natural disaster score at the 28th percentile puts it well below the national median for hazard exposure. Custer County residents can take confidence from a 28th percentile ranking, but even lower-risk counties benefit from a practiced household communication plan and awareness of the specific hazards listed above.

Hazard Breakdown

Wildfire risk is Custer County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 50th percentile nationally. Additional tracked hazards include flood (43th percentile), earthquake (20th percentile).

Preparedness Context

With wildfire ranked at the 82th percentile nationally, Custer County is in a zone where air quality can deteriorate rapidly before structures are threatened. An N95 respirator and a HEPA air purifier are practical items for Custer County households to have on hand before fire season. Alongside wildfire, tornado at the 50th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Custer County households — and the insurance review is the one most often deferred by Custer County residents and most costly to skip when a fire event actually occurs.

Regional Context

Custer County's risk score is broadly comparable to the Nebraska county average, with a 2.2-point gap that places the county near the center of the state's hazard distribution.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. 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 Custer County higher risk than average?
Custer County's composite risk score of 28th percentile is above the Nebraska state average of 26th percentile. This elevated risk is driven by wildfire exposure (82th percentile), along with tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
