Tornadoes and wildfires drive risk

Tornado risk reaches 95.74—among the state's highest—making severe convective storms Lamar's defining hazard. Wildfire risk of 86.13 compounds exposure, with earthquake risk of 66.22 adding a third significant concern uncommon in most Texas counties.

Invest in storm shelter and preparedness

Lamar County residents should prioritize homeowners insurance that covers wind damage and maintain a certified storm shelter or safe room given the 95.74 tornado risk score.

Risk Verdict

At the 80th percentile nationally, Lamar County experiences a manageable level of natural hazard risk that falls below the U.S. median. High composite risk signals that multiple hazard types are elevated simultaneously; planning for more than one scenario is important in Lamar County.

Hazard Breakdown

Tornado risk is Lamar County's dominant natural hazard, ranked at the 96th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 86th percentile nationally. Additional tracked hazards include earthquake (66th percentile), flood (62th percentile), hurricane (56th percentile).

Preparedness Context

Lamar County's primary hazard, tornado, ranks at the 96th percentile nationally. In Lamar County, mobile homes and manufactured housing face significantly higher tornado risk than site-built structures; residents in these homes should identify the nearest permanent community shelter in advance. Alongside tornado exposure, wildfire at the 86th percentile nationally means Lamar County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. The highest-risk window for tornado fatalities is overnight, when Lamar County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Lamar County households.

Regional Context

Lamar County falls 30.5 points above Texas's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
