Risk Overview
About Natural Disaster Risk in Hidalgo County, Texas
Hidalgo faces exceptionally high national risk
Hidalgo County's composite risk score of 99.01 ranks it as "Relatively High" and among the most at-risk counties in the entire United States. This exceptional exposure reflects the Rio Grande Valley's vulnerability to hurricanes, floods, and multiple other hazards.
Highest-risk county in all of Texas
Hidalgo County's score of 99.01 is the absolute highest in Texas and more than double the state average of 49.00. The county's southern location along the Gulf Coast and Mexican border creates unmatched exposure to hurricanes, storm surge, and flooding.
Dramatically riskier than surrounding counties
Hidalgo County's 99.01 score far exceeds all other Texas counties; the next-closest is Hays County at 90.55. Its unique geographic position at the southern tip of Texas creates hazard exposures unmatched elsewhere in the state.
Hurricanes and floods dominate your profile
Hurricane risk reaches 99.50—the highest possible exposure in the state—while flood risk stands at 96.44, creating a severe coastal weather double threat. Tornado risk of 95.99 and earthquake risk of 79.01 complete an exceptionally hazardous profile.
Comprehensive coverage is non-negotiable
Hidalgo residents must carry homeowners insurance, separate flood insurance, and wind/hail coverage to address the county's extreme exposure to hurricanes and flooding. Given the 99+ risk scores for both hurricanes and floods, adequate insurance is essential for financial recovery after major events.

Hazard Breakdown
Hurricane risk is Hidalgo County's dominant natural hazard, ranked at the 99th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 96th percentile nationally. Additional tracked hazards include tornado (96th percentile), wildfire (84th percentile), earthquake (79th percentile).
Preparedness Context
At the 99th percentile nationally for hurricane risk, Hidalgo 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. Flood at the 96th percentile nationally is Hidalgo County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. For Hidalgo 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 50.0 points above the Texas state average puts Hidalgo County in a higher-risk category than most counties in the state.
