Risk Overview

About Natural Disaster Risk in Houston County, Texas

Houston County's moderate risk profile

Houston County scores 60.66 on the composite risk scale, placing it above the national average and reflecting a relatively low overall risk rating. This score indicates the county faces moderate natural disaster exposure compared to the typical U.S. county, driven primarily by hurricane and wildfire threats.

Above average risk for Texas

At 60.66, Houston County ranks above Texas's state average composite risk score of 49.00, placing it in the upper-middle tier of risk among the state's 254 counties. The county's exposure is notably elevated by dual threats from hurricanes and wildfires.

Riskier than nearby counterparts

Houston County faces significantly higher risk than neighboring Angelina County and similar East Texas communities, primarily due to its higher hurricane risk score of 77.56. The county's wildfire risk of 77.80 also exceeds that of most immediate neighbors, creating a compounded hazard environment.

Hurricanes and wildfires dominate

Hurricane risk ranks highest at 77.56, reflecting the county's position in the coastal exposure zone where tropical systems regularly impact the region. Wildfire risk at 77.80 presents the second major threat, with tornado risk at 63.74 adding additional seasonal weather exposure.

Dual coverage protects Houston County homes

Given the elevated hurricane and wildfire risks, homeowners should prioritize comprehensive wind and hail coverage, plus verified wildfire insurance provisions in their policies. Flood insurance remains essential regardless of risk level, as it's typically excluded from standard homeowners policies.

Risk Verdict

Houston County ranks at the 61th percentile nationally for natural disaster risk — below the median for U.S. counties. Residents are encouraged to understand which hazards dominate locally and tailor their preparedness accordingly.

Hazard Breakdown

Wildfire risk is Houston County's dominant natural hazard, ranked at the 78th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 78th percentile nationally. Additional tracked hazards include tornado (64th percentile), flood (40th percentile), earthquake (31th percentile).

Preparedness Context

Houston County's dominant hazard is wildfire, ranked at the 78th percentile nationally. Maintaining at least 30 feet of lean, clean vegetation around structures in Houston County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. Alongside wildfire, hurricane at the 78th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Houston County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.

Regional Context

Compared to other Texas counties, Houston County runs 11.7 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.
