Risk Overview

About Natural Disaster Risk in Zavala County, Texas

Zavala County presents relatively low disaster risk

Zavala County's composite risk score of 53.63 places it in the relatively low risk category and near the national average for natural hazard exposure. The county's profile is shaped by dual flood and hurricane threats balanced against very low earthquake exposure.

Slightly above Texas average but manageable

Zavala County scores 53.63, marginally above the Texas state average of 49.00, placing it in the middle tier of risk across the state. The elevation is driven by flood (67.02) and hurricane (60.28) risks while other hazards remain minimal.

Moderate risk between safest and riskiest peers

Zavala County (53.63) ranks between its neighbors, comparable to Wise County (58.97) but noticeably safer than Wood County (63.23) and higher-risk than Young County (36.35) and Zapata County (31.36). Its flood risk (67.02) is the highest among its peer group.

Flood and hurricane risks drive Zavala exposure

Flood risk reaches 67.02 in Zavala County—the county's dominant hazard—while hurricane risk of 60.28 reflects Gulf Coast proximity and storm exposure during Atlantic hurricane season. Tornado (28.91), wildfire (35.34), and earthquake (7.16) risks remain minimal by comparison.

Flood and hurricane coverage are essential here

Zavala County homeowners must secure separate flood insurance, as standard homeowners policies exclude flood damage and the county's 67.02 flood risk demands specific coverage. Verify your policy includes hurricane and wind protection, and consider elevated or reinforced construction if you live in a flood-prone area.

Risk Advisory: Zavala County

Risk Verdict

Zavala County's FEMA risk score places it at the 54th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Flood risk is Zavala County's dominant natural hazard, ranked at the 67th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 60th percentile nationally. Additional tracked hazards include wildfire (35th percentile), tornado (29th percentile), earthquake (7th percentile).

Preparedness Context

At the 67th percentile nationally for flood risk, Zavala 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. Alongside flooding, hurricane exposure at the 60th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A tested family preparedness plan specific to Zavala 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

Zavala County sits within 4.6 composite points of the Texas state average, suggesting the county's hazard exposure is representative of the broader regional pattern.
