Risk Overview

About Natural Disaster Risk in Gonzales County, Texas

Gonzales faces above-average disaster risk

With a composite risk score of 85.66, Gonzales County ranks as relatively moderate—significantly higher than the U.S. average and well above Texas's state average of 49.00. This elevated score reflects multiple serious hazards affecting the community, from hurricanes to flooding.

Among Texas's highest-risk counties

Gonzales ranks in the upper tier of Texas counties for overall disaster risk, driven by exceptional hurricane (88.65) and flood (90.39) scores that far exceed state norms. The county's exposure to Gulf Coast storms makes it one of Texas's most vulnerable areas.

Riskier than most nearby counties

Gonzales's score of 85.66 exceeds neighboring Guadalupe County (91.51) and Grimes County (56.97), placing it among the region's highest-risk areas. Its hurricane and flood vulnerabilities are notably higher than inland counties to the north and west.

Hurricanes and floods dominate threats

Gonzales County faces exceptional hurricane risk (88.65) and flood risk (90.39), both well above state averages—typical for counties near the Gulf Coast. Tornadoes (72.49) and wildfires (73.09) also pose significant secondary threats to homes and infrastructure.

Prioritize flood and hurricane coverage

Standard homeowners insurance does not cover flood damage, making separate flood insurance essential for Gonzales County residents given the 90.39 flood risk score. Consider hurricane-resistant upgrades and ensure your policy includes wind damage coverage, especially if you're near the coast or in storm-surge zones.

Risk Verdict

FEMA's National Risk Index rates Gonzales County at the 86th percentile nationally — above average and worth proactive preparation. Residents should prioritize a formal household emergency plan, including evacuation routes, insurance review, and a well-stocked emergency kit.

Hazard Breakdown

Flood risk is Gonzales County's dominant natural hazard, ranked at the 90th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 89th percentile nationally. Additional tracked hazards include wildfire (73th percentile), tornado (72th percentile), earthquake (21th percentile).

Preparedness Context

Flood risk is Gonzales County's top hazard at the 90th percentile nationally. Households in or near designated flood zones face elevated financial exposure; flood insurance typically requires a 30-day waiting period before it takes effect, so applying before the season is advisable. Alongside flooding, hurricane exposure at the 89th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Households across Gonzales County should identify the nearest community shelter and keep a basic emergency kit — water, non-perishable food, medications, flashlight, and battery radio — in a location easy to grab quickly.

Regional Context

Gonzales County is 36.7 composite risk points above the Texas average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.
