Risk Overview

About Natural Disaster Risk in Lincoln County, South Dakota

Lincoln County's risk ranks above average nationally

With a composite risk score of 62.98, Lincoln County faces above-average natural disaster exposure compared to the national baseline. This "Relatively Low" rating masks significant variation: while the county sits well below the state average of 26.84, individual hazards like tornadoes (93.32) pose outsized threats. Understanding your specific exposures—not just the overall score—helps you prepare appropriately.

Lincoln ranks among South Dakota's highest-risk counties

Lincoln County's composite risk score of 62.98 significantly exceeds South Dakota's state average of 26.84, making it one of the state's more hazard-exposed areas. The county's tornado risk score of 93.32 is particularly acute, reflecting historical patterns in the region. This elevated profile means residents should prioritize hazard awareness and preparedness more than many neighbors statewide.

Lincoln faces higher risks than surrounding counties

Among its neighbors, Lincoln County's composite risk of 62.98 substantially exceeds McCook County (43.45) and Meade County (49.46). Lincoln's tornado risk score of 93.32 dwarfs that of McCook (67.46), signaling a regional hot spot for severe weather. If you're relocating within the region, risk profiles vary considerably over short distances.

Tornadoes and wildfires dominate local hazards

Lincoln County's tornado risk (93.32) represents the county's most acute natural disaster threat, far exceeding state and national norms and warranting safe-room planning and early-warning awareness. Wildfire risk (65.11) ranks as the second major concern, while flood risk (56.62) also exceeds state averages. These three hazards should anchor your household preparedness strategy.

Secure comprehensive coverage for tornado exposure

Lincoln County's exceptional tornado risk demands that homeowners verify their policies explicitly cover wind and hail damage—standard homeowners policies often exclude or limit these coverages. Given the county's elevated wildfire (65.11) and flood (56.62) risks, bundling homeowners, auto, and separate flood insurance provides fuller protection. Review and update your coverage annually, especially after severe weather seasons.

Risk Verdict

Lincoln County ranks at the 63th percentile nationally for natural disaster risk — below the median for U.S. counties. Residents are encouraged to understand which hazards dominate locally and tailor their preparedness accordingly.

Hazard Breakdown

Tornado risk is Lincoln County's dominant natural hazard, ranked at the 93th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 65th percentile nationally. Additional tracked hazards include flood (57th percentile), earthquake (25th percentile).

Preparedness Context

Lincoln County ranks at the 93th percentile nationally for tornado exposure. Unlike many slow-onset hazards, tornadoes in Lincoln County can reach full intensity in minutes; a pre-practiced household shelter plan matters far more than stockpiled supplies. The secondary wildfire hazard at the 65th percentile nationally adds seasonal complexity to Lincoln County's preparedness calendar, since wildfire and tornado risk often peak at different points in the year. Lincoln County county emergency management typically publishes annual severe-weather preparedness guides tailored to local tornado patterns; households benefit from reviewing these before storm season begins each spring.

Regional Context

Compared to other South Dakota counties, Lincoln County runs 36.1 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.
