Risk Overview

About Natural Disaster Risk in Crawford County, Iowa

Crawford County faces above-average risk

Crawford's composite risk score of 60.85 exceeds Iowa's state average of 39.68, placing it in the relatively-low-risk tier nationally. West-central Iowa experiences concentrated hazard exposure, particularly from tornadoes and wildfires.

Among Iowa's more vulnerable counties

Crawford ranks in the upper third of Iowa's 99 counties by composite risk with its 60.85 score. This positioning reflects above-average tornado and wildfire exposure compared to most Iowa communities.

Higher risk than most nearby counties

Crawford's 60.85 score significantly exceeds nearby Chickasaw (31.74) and Buena Vista counties, though aligns with western Iowa's generally elevated tornado exposure. Its topography and continental climate create this elevated vulnerability.

Tornado and wildfire drive exposure

Crawford faces tornado risk of 82.38—among Iowa's highest—combined with wildfire risk of 46.22 that exceeds state average. Flood (56.08) and earthquake (9.92) risks remain lower but still merit attention.

Tornado and wildfire coverage critical

Crawford residents need robust windstorm insurance for tornado protection, which standard policies exclude entirely. Those near grasslands or forests should ensure wildfire coverage and maintain defensible space around structures.

Risk Verdict

Crawford County has a below-average natural disaster risk profile, scoring at the 61th percentile nationally under FEMA's National Risk Index. Households in Crawford County benefit from knowing which individual hazard types — flood, wildfire, tornado, or hurricane — are the primary contributors.

Hazard Breakdown

Tornado risk is Crawford County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 56th percentile nationally. Additional tracked hazards include wildfire (46th percentile), earthquake (10th percentile), hurricane (0th percentile).

Preparedness Context

Tornado risk is Crawford County's top-ranked natural hazard at the 82th percentile nationally. For Crawford County households, the most protective action available is identifying a reinforced interior room on the lowest floor — a bathroom, closet, or central hallway away from windows. The secondary flood hazard at the 56th percentile nationally adds seasonal complexity to Crawford County's preparedness calendar, since flood and tornado risk often peak at different points in the year. A battery-powered NOAA All Hazards weather radio with an auto-alert tone is the highest-leverage single item for tornado preparedness in Crawford County, since it delivers warnings even when power is out and phone networks are congested.

Regional Context

Crawford County's composite risk score sits 21.2 points above the Iowa county average, placing it among the more hazard-exposed counties in the state.

Frequently Asked Questions

What is the natural disaster risk in Crawford County, IA?
Crawford County has a FEMA National Risk Index rating of Relatively Low, placing it in the 61th percentile nationally out of 3,144 counties. This composite score reflects the county's overall exposure to natural hazards including floods, wildfires, tornadoes, earthquakes, and hurricanes, weighted by expected annual loss and social vulnerability.
What types of natural hazards affect Crawford County?
Crawford County is evaluated for five major natural hazard types: tornado (82th percentile), flooding (56th percentile), wildfire (46th percentile), earthquake (10th percentile), hurricane (0th percentile). The highest-risk hazard is tornado at the 82th percentile nationally. These scores are derived from FEMA's National Risk Index, which analyzes expected annual loss, social vulnerability, and community resilience for each hazard type.
How does Crawford County risk compare to the Iowa average?
Crawford County's composite risk percentile is 61th, compared to the Iowa state average of 40th percentile. The state's overall risk rating is Very Low. This means Crawford County faces higher natural disaster risk than the typical county in Iowa.
Is Crawford County at risk for tornado?
Yes, Crawford County's tornado risk is at the 82th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Crawford County is at the 56th percentile.
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 Crawford County higher risk than average?
Crawford County's composite risk score of 61th percentile is above the Iowa state average of 40th percentile. This elevated risk is driven by tornado exposure (82th percentile), along with flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
