Risk Overview

About Natural Disaster Risk in Weld County, Colorado

Weld ranks among America's highest-risk counties

Weld County scores 89.15, earning a Relatively Moderate rating and more than doubling the national average. The county faces the most comprehensive natural hazard exposure of any area analyzed here.

Colorado's riskiest county

Weld's 89.15 score is more than double the Colorado state average of 40.67, making it the state's most hazard-exposed county. Its risk profile stands apart across all major categories.

Significantly riskier than all adjacent counties

Weld dramatically outranks neighboring counties: Washington (11.99), Yuma (36.80), and even Summit County (60.21) are far safer. Its combination of plains hazards and urban exposure is unique in the region.

All hazards pose substantial threats

Weld faces elevated risk across all four measured hazard types: tornado (95.07), flood (88.45), wildfire (87.69), and earthquake (77.83). No single hazard dominates; residents face compound exposure.

Comprehensive insurance coverage is essential

Weld County residents should secure homeowner's policies covering wind, hail, and tornado damage, plus separate flood insurance through FEMA's National Flood Insurance Program. Wildfire coverage should also be verified or added, and an evacuation plan for multiple hazard types is critical.

Risk Verdict

FEMA's National Risk Index rates Weld County at the 89th percentile nationally — above average and worth proactive preparation. Residents should prioritize a formal household emergency plan, including evacuation routes, insurance review, and a well-stocked emergency kit.

Hazard Breakdown

Tornado risk is Weld County's dominant natural hazard, ranked at the 95th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 88th percentile nationally. Additional tracked hazards include wildfire (88th percentile), earthquake (78th percentile).

Preparedness Context

With tornado ranked at the 95th percentile nationally, Weld County sits in a high-exposure zone where the difference between outcomes often comes down to proximity to a reinforced interior shelter and seconds of warning time. Flood is the second hazard driver for Weld County at the 88th percentile nationally, meaning households should maintain awareness of both severe-weather and flood-specific warning systems. For Weld County households, safe rooms certified to FEMA 320/361 standards offer the highest protection during a direct tornado hit; households without a safe room should locate the innermost lowest-floor room in their building and practice the route to it before storm season.

Regional Context

Weld County is 48.5 composite risk points above the Colorado average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.

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 Weld County higher risk than average?
Weld County's composite risk score of 89th percentile is above the Colorado state average of 41th percentile.
