Risk Overview

About Natural Disaster Risk in Frio County, Texas

Frio County Moderately Above National Risk

Frio's composite risk score of 55.95 classifies it as relatively low risk but still exceeds the national average around 50. The county's exposure stems mainly from wildfire and hurricane hazards, which dominate its overall risk profile.

Slightly Elevated for South Texas

At 55.95, Frio's score surpasses Texas's state average of 49.00, placing it above the middle of the state's risk distribution. This south-central location brings hurricane exposure and brushland fire danger that shape the county's insurance landscape.

Similar to Surrounding South Texas Counties

Frio's score of 55.95 aligns closely with nearby LaSalle and Atascosa counties, all sharing similar wildfire and hurricane vulnerabilities. The region's semiarid terrain and proximity to the Gulf Coast create consistent risk patterns across multiple counties.

Wildfire and Hurricane Threats

Frio's top hazards are wildfire (75.16) and hurricane (71.59), both well above national norms, while tornado risk remains moderate at 53.37. Dry brush and grasslands fuel rapid wildfire spread, while Gulf proximity brings seasonal hurricane exposure from June through November.

Fireproof Landscaping and Wind Insurance

Frio residents should clear brush and dead vegetation within 30 feet of structures to reduce wildfire risk, and maintain robust wind coverage for hurricane season. Flood insurance is recommended for properties in flood-prone areas near the Frio River and its tributaries.

Risk Advisory: Frio County

Risk Verdict

Natural hazard pressure in Frio County is below the national midpoint, with a composite score at the 56th percentile. Proactive emergency planning and awareness of the specific hazards driving Frio County's score can meaningfully reduce household risk.

Hazard Breakdown

Wildfire risk is Frio County's dominant natural hazard, ranked at the 75th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 72th percentile nationally. Additional tracked hazards include tornado (53th percentile), flood (47th percentile), earthquake (11th percentile).

Preparedness Context

With wildfire ranked at the 75th percentile nationally, Frio 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 Frio County households to have on hand before fire season. The county's hurricane exposure at the 72th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Frio County households — and the insurance review is the one most often deferred by Frio County residents and most costly to skip when a fire event actually occurs.

Regional Context

Frio County is 6.9 composite risk points above the Texas average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.

The highest-risk hazard is wildfire at the 75th 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 Frio County risk compare to the Texas average?
Frio County's composite risk percentile is 56th, compared to the Texas state average of 49th percentile. The state's overall risk rating is Relatively Low. This means Frio County faces higher natural disaster risk than the typical county in Texas.

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 Frio County higher risk than average?
Frio County's composite risk score of 56th percentile is above the Texas state average of 49th percentile. This elevated risk is driven by wildfire exposure (75th percentile), along with hurricane and tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
