Risk Overview

About Natural Disaster Risk in Wilson County, Texas

Wilson faces above-average natural risk

Wilson County's composite risk score of 75.54 sits well above the national average, though rated "Relatively Low" in context. This score reflects a county where coastal and severe weather hazards create genuine exposure despite the classification.

Above Texas average, mid-range for state

Wilson's score of 75.54 exceeds the Texas state average of 49.00, placing it in the higher-risk tier of Texas counties. The county sits in a middle-to-upper range when compared across the state.

More exposed than most nearby counties

Wilson County (75.54) faces higher risk than southern neighbors and sits between Willacy County (77.48) and Wharton County (83.02) in the coastal risk spectrum. Its hazard profile reflects both inland and coastal threats.

Floods, tornadoes, and hurricanes matter most

Wilson's flood risk of 84.38 is the county's primary hazard, followed by tornado risk of 77.99 and hurricane risk of 63.79. Wildfire risk of 71.66 adds a fourth significant concern across varied landscapes.

Prioritize flood and wind protection

Wilson County residents should secure homeowners insurance with comprehensive wind coverage and a separate flood insurance policy—flood risk here is substantial. If you're in a rural or wildland-adjacent area, verify wildfire coverage as well.

Risk Advisory: Wilson County

Risk Verdict

Wilson County's FEMA risk score places it at the 76th percentile nationally, indicating lower-than-typical exposure for a U.S. county. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Wilson County residents.

Hazard Breakdown

Flood risk is Wilson County's dominant natural hazard, ranked at the 84th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 78th percentile nationally. Additional tracked hazards include wildfire (72th percentile), hurricane (64th percentile), earthquake (15th percentile).

Preparedness Context

At the 84th percentile nationally for flood risk, Wilson County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. The county's second-ranked hazard, tornado at the 78th percentile nationally, means Wilson County residents face compounding risks from multiple natural hazard types during peak seasons. A tested family preparedness plan specific to Wilson County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.

Regional Context

The Texas county average is 26.5 composite points below Wilson County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
