Risk Overview

About Natural Disaster Risk in Duval County, Texas

Duval County's Moderate Risk Level

Duval County scores 54.42 on the national composite risk scale, earning a Relatively Low rating and sitting slightly above the national average. This modest elevation reflects the county's exposure to several significant hazards, particularly from coastal and tropical weather systems. Overall, Duval residents face moderate but manageable disaster risk compared to the broader U.S.

Slightly Above Texas Average

At 54.42, Duval County exceeds Texas's average composite risk score of 49.00 by about 11%, indicating greater exposure than most of the state. The county ranks in the middle tier of Texas hazard vulnerability, with risk significantly higher than Panhandle communities but lower than major metropolitan corridors. This positioning reflects Duval's South Texas location and proximity to coastal systems.

Higher Risk Than Regional Peers

Duval County's 54.42 score surpasses Edwards County (5.73), making it substantially more exposed to natural disasters than its inland neighbor. However, it remains considerably safer than Erath County (75.00) and Ector County (82.82). Duval's risk profile places it at the middle of the South Texas hazard spectrum.

Hurricane and Wildfire Threats

Hurricane risk dominates at 74.84—among the highest hazard scores in Duval County—reflecting its coastal position and tropical storm vulnerability. Wildfire risk ranks second at 52.42, while flood risk at 28.59 adds a secondary concern. Together, these three hazards account for most of the county's natural disaster exposure.

Hurricane and Wildfire Insurance Essential

Duval County residents must prioritize hurricane-specific wind and hail coverage, which standard policies often exclude or limit significantly. Supplemental wildfire insurance is equally critical given the county's substantial exposure to brush fires and grassland burns. Review your policy deductibles and coverage limits annually before hurricane season begins each June.

Risk Advisory: Duval County

Risk Verdict

Duval County sits below the national average for natural disaster exposure, ranking at the 54th percentile across all U.S. counties. Understanding the specific hazards behind Duval County's ranking helps residents prioritize where to direct emergency planning efforts.

Hazard Breakdown

Hurricane risk is Duval County's dominant natural hazard, ranked at the 75th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 52th percentile nationally. Additional tracked hazards include tornado (32th percentile), flood (29th percentile), earthquake (8th percentile).

Preparedness Context

At the 75th percentile nationally for hurricane risk, Duval County is in a zone where flood insurance matters beyond the primary wind risk: NFIP flood insurance requires a 30-day waiting period before taking effect, making off-season enrollment the correct timing. Wildfire at the 52th percentile nationally is Duval County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. For Duval County households, the hurricane preparedness calendar matters: flood insurance has a 30-day waiting period, wind-hardening retrofits take weeks to schedule, and evacuation route scouting is best done before a storm watch is issued.

Regional Context

A composite score 5.4 points above the Texas state average puts Duval County in a higher-risk category than most counties in the state.

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 Duval County higher risk than average?
Duval County's composite risk score of 54th percentile is above the Texas state average of 49th percentile.
