Risk Overview

About Natural Disaster Risk in Knox County, Texas

Knox County faces minimal national risk

Knox County's composite risk score of 17.84 places it well below the national average, earning a "Very Low" rating. The county's remote location and distance from major hazard zones create one of Texas's safest natural disaster profiles.

Among Texas's safest counties

With a composite score of 17.84 versus Texas's state average of 49.00, Knox County ranks as one of the state's lowest-risk areas. This score reflects limited exposure to most major natural hazards.

Safer than comparable Texas counties

Knox County's risk score of 17.84 is substantially lower than neighboring Lamb County (61.23) and La Salle County (22.55). Among its peers, Knox stands out as exceptionally protected from major disaster exposure.

Wildfire presents the clearest threat

Wildfire risk of 43.67 represents Knox County's most elevated hazard, though still below state averages. Tornado and hurricane risks remain minimal at 28.15 and 28.99 respectively.

Standard homeowners coverage generally sufficient

Knox County's low overall risk profile means standard homeowners insurance typically provides adequate protection for most residents. Nonetheless, those in rural areas should maintain defensible space and brush clearance to reduce wildfire vulnerability.

Risk Advisory: Knox County

Risk Verdict

Knox County's overall natural disaster score at the 18th percentile puts it well below the national median for hazard exposure. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Knox County's favorable 18th percentile ranking.

Hazard Breakdown

Wildfire risk is Knox County's dominant natural hazard, ranked at the 44th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 29th percentile nationally. Additional tracked hazards include tornado (28th percentile), earthquake (16th percentile), flood (5th percentile).

Preparedness Context

With wildfire ranked at the 44th percentile nationally, Knox County is in a zone where air quality can deteriorate rapidly before structures are threatened. An N95 respirator and a HEPA air purifier are practical items for Knox County households to have on hand before fire season. A secondary hurricane exposure at the 29th percentile nationally means Knox County residents face hazards from two distinct natural peril categories during different seasons. Defensible space, insurance review, and an evacuation plan are the three preparedness pillars for Knox County households — and the insurance review is the one most often deferred by Knox County residents and most costly to skip when a fire event actually occurs.

Regional Context

Knox County's composite risk score sits 31.2 points below the Texas county average, reflecting a more favorable hazard environment than the state typical.
