Risk Overview

About Natural Disaster Risk in Wharton County, Texas

Wharton's risk sits well above average

With a composite risk score of 83.02, Wharton County faces significantly higher natural disaster risk than the typical U.S. county. This "Relatively Moderate" rating reflects exposure to multiple hazard types that demand preparation and insurance planning.

A higher-risk Texas county

Wharton ranks among the riskier counties in Texas, with a score of 83.02 compared to the state average of 49.00. This makes it one of the counties where residents face elevated exposure across several disaster categories.

Riskier than most Coastal Bend peers

Wharton's risk profile exceeds that of neighboring Willacy County (77.48) and Wilson County (75.54), placing it in a higher-risk tier for the region. Its hurricane exposure particularly outpaces nearby counties, while flood risk remains a shared concern across the coastal area.

Hurricanes and tornadoes pose top threats

Wharton's hurricane risk score of 94.83 is exceptionally high—among the state's most exposed counties—while tornado risk of 72.42 adds a secondary severe weather threat. Flood risk of 69.82 rounds out a trio of serious hazards that shape the county's disaster preparedness needs.

Prioritize wind and flood coverage now

Given Wharton's extreme hurricane exposure, comprehensive homeowners insurance with adequate wind damage coverage is essential. If you live in a flood-prone area, flood insurance through the National Flood Insurance Program should be a priority—standard homeowners policies do not cover flood damage.

Risk Verdict

Natural hazard risk in Wharton County is higher than the majority of U.S. counties, with a national composite rank of 83th. Wharton County's elevated composite score reflects cumulative multi-hazard exposure; households should prepare for the county's two or three primary hazard types.

Hazard Breakdown

Hurricane risk is Wharton County's dominant natural hazard, ranked at the 95th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 72th percentile nationally. Additional tracked hazards include flood (70th percentile), wildfire (53th percentile), earthquake (26th percentile).

Preparedness Context

At the 95th percentile nationally for hurricane risk, Wharton County is in a zone where flood insurance matters beyond the primary wind risk: NFIP flood insurance requires a 30-day waiting period before taking effect, making off-season enrollment the correct timing. Wharton County's tornado exposure at the 72th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. For Wharton County households, the hurricane preparedness calendar matters: flood insurance has a 30-day waiting period, wind-hardening retrofits take weeks to schedule, and evacuation route scouting is best done before a storm watch is issued.

Regional Context

A composite score 34.0 points above the Texas state average puts Wharton County in a higher-risk category than most counties in the state.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Wharton County higher risk than average?
Wharton County's composite risk score of 83th percentile is above the Texas state average of 49th percentile. This elevated risk is driven by hurricane exposure (95th percentile), along with tornado and flooding and wildfire risk.
