About Natural Disaster Risk in Nacogdoches County, Texas

Nacogdoches: Elevated National Risk Level

Nacogdoches County scores 80.73 on the national composite risk scale, ranking as "Relatively Low" but exceeding Texas's state average of 49.00 by a significant margin. This East Texas county faces above-average disaster exposure, particularly from flood, tornado, and hurricane hazards.

High-Risk East Texas County

Nacogdoches ranks in the upper-middle tier of Texas counties for natural disaster risk, driven by its position in an active tornado corridor and exposure to tropical weather systems. The county's composite score places it among the state's more hazardous communities outside of coastal zones.

Riskier Than Most East Texas Peers

Nacogdoches's score of 80.73 exceeds surrounding rural East Texas counties like Morris (34.54) and Newton (27.16), reflecting its greater exposure to tornado and hurricane pathways. The county's risk profile more closely resembles central Texas communities than its immediate geographic neighbors.

Tornado and Hurricane Threats Dominate

Nacogdoches faces exceptional tornado risk at 94.94 and hurricane risk at 83.40, making severe convective and tropical storms the county's primary threats. Flood risk reaches 75.57, while wildfire (78.82) and earthquake (48.98) risks remain secondary concerns.

Multi-Hazard Protection Essential

Nacogdoches residents should carry comprehensive homeowners insurance with windstorm coverage and consider a separate flood policy given the county's flood exposure. Develop a tornado safety plan with a designated shelter, maintain landscaping to reduce wildfire risk, and keep emergency supplies stocked year-round.
