Risk Overview
About Natural Disaster Risk in Dimmit County, Texas
Dimmit County experiences low risk
Dimmit County's composite risk score of 35.88 places it in the "Very Low" category, well below the national average. This South Texas county sits at the intersection of multiple hazard zones but experiences relatively minimal combined exposure.
Below Texas average, relatively safe
At 35.88, Dimmit County scores below the Texas state average of 49.00, ranking among the state's lower-risk counties. The county's inland location and semi-arid climate buffer it against many major hazard types.
Safest in South Texas peer group
Dimmit's 35.88 score edges out nearby Gulf Coast counties like DeWitt (83.91), whose 48-point gap reflects coastal hurricane and flood exposure. Compared to Panhandle neighbors like Deaf Smith (61.80), Dimmit benefits from lower tornado and wildfire risk.
Hurricane risk and wildfire matter most
Hurricane risk of 61.79 is Dimmit's highest hazard score, reflecting South Texas geography; wildfire risk (54.55) ranks second. Tornado (28.24), flood (19.37), and earthquake (8.75) risks remain relatively modest.
Hurricane preparedness plus wildfire awareness
Standard homeowners insurance covers wind damage but not flood; given the 61.79 hurricane score, verify policy limits for wind coverage. Maintain defensible space around structures, clear gutters, and develop a hurricane evacuation plan for storm season.

Hazard Breakdown
Hurricane risk is Dimmit County's dominant natural hazard, ranked at the 62th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 55th percentile nationally. Additional tracked hazards include tornado (28th percentile), flood (19th percentile), earthquake (9th percentile).
Preparedness Context
Dimmit County ranks at the 62th percentile nationally for hurricane risk. For coastal counties, wind-resistant shutters or impact-rated windows represent the highest single structural investment for reducing property damage. Dimmit County's wildfire exposure at the 55th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. For extended post-storm outages common in Dimmit County's hurricane zone, a portable generator (operated outdoors only) and a supply of non-perishable food for at least seven days provides meaningful household resilience.
Regional Context
A composite score 13.1 points below the Texas state average puts Dimmit County in a better-than-typical position relative to neighboring counties.
