Risk Overview
About Natural Disaster Risk in DeWitt County, Texas
DeWitt County faces substantial disaster risk
DeWitt County's composite risk score of 83.91 places it in the "Relatively Moderate" category, well above the national average. This South Texas Gulf Coast region experiences concentrated exposure to weather and water hazards.
Mid-range risk for Texas
At 83.91, DeWitt County scores significantly above the Texas state average of 49.00, ranking it among the higher-risk counties statewide. The county's proximity to the Gulf Coast and inland waterways creates distinct vulnerability patterns.
Gulf proximity drives regional risk
DeWitt's 83.91 score exceeds nearby inland counties but reflects the shared hurricane exposure of South Texas coastal zones. Counties farther inland like Dimmit (35.88) demonstrate how Gulf proximity dramatically elevates composite risk.
Hurricanes and floods reign supreme
Hurricane risk of 90.28 and flood risk of 89.22 are DeWitt's primary concerns, reflecting its Gulf Coast and river-bottom geography. Tornado risk (70.74) and wildfire risk (67.59) round out a formidable hazard portfolio.
Flood and hurricane coverage essential
Flood insurance is non-negotiable given the 89.22 flood and 90.28 hurricane scores; standard homeowners policies exclude both. Ensure your policy explicitly covers hurricane/wind damage, maintain year-round property maintenance, and establish a family evacuation plan for storm season.

Risk Verdict
DeWitt County registers a moderately elevated natural disaster risk, ranking at the 84th percentile across all U.S. counties. High composite risk signals that multiple hazard types are elevated simultaneously; planning for more than one scenario is important in DeWitt County.
Hazard Breakdown
Hurricane risk is DeWitt County's dominant natural hazard, ranked at the 90th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 89th percentile nationally. Additional tracked hazards include tornado (71th percentile), wildfire (68th percentile), earthquake (21th percentile).
Preparedness Context
DeWitt County's primary hazard, hurricane, ranks at the 90th percentile nationally. Having a designated out-of-area contact, a pre-packed go-bag with medications and documents, and a confirmed evacuation route reduces decision-making load when a storm intensifies rapidly. Flood, the county's second-ranked hazard at the 89th percentile nationally, represents an additional preparedness consideration for DeWitt County independent of hurricane season. The National Hurricane Center's official forecast cone and local NWS office watches and warnings are the authoritative sources for DeWitt County storm tracking; households benefit from bookmarking these before storm season rather than relying on social media during an event.
Regional Context
DeWitt County falls 34.9 points above Texas's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
