About Natural Disaster Risk in Starr County, Texas

Starr: Among America's Riskiest

Starr County's composite risk score of 84.80 ranks at the very top of elevated risk nationally. Your county faces one of the highest natural disaster exposure profiles in the entire United States.

Highest Risk in Texas

At 84.80, Starr County is the riskiest county in Texas, exceeding the state average of 49.00 by 73%. Only Smith County (84.16) approaches this level of exposure.

Riskiest in South Texas

Starr County's risk far exceeds all neighboring counties, standing isolated in its extreme exposure profile. No adjacent South Texas county comes close to Starr's 84.80 composite score.

Wildfire and Hurricanes Converge

Wildfire risk (84.89) and hurricane risk (78.77) create a dual-threat environment in Starr County. Flood risk (72.39) adds a third significant concern, making this county vulnerable across multiple hazard types.

Comprehensive Protection Essential

Starr County residents must carry flood insurance and confirm their policies cover hurricane wind damage—basic homeowners coverage alone is insufficient. Consider additional wildfire coverage and discuss earthquake protection with your agent, given elevated exposure across all major hazards.

Preparedness Context

At the 85th percentile nationally for wildfire risk, Starr County households benefit from creating defensible space — a buffer of reduced vegetation around structures — and reviewing whether homeowners insurance covers wildfire damage in this region. The county's hurricane exposure at the 79th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Enrolling in the county's wireless emergency alert system and keeping a vehicle at least half-full during peak fire season are low-cost habits that dramatically reduce evacuation lag time for Starr County residents.

Regional Context

At 35.8 points above the Texas state average, Starr County carries meaningfully higher natural disaster exposure than a typical Texas county.
