Risk Overview
Throckmorton County carries a very low composite natural disaster risk, with a National Risk Index score of 3.3 out of 100 — placing it in the 3rd national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
The county's risk is driven primarily by drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $1M in expected annual loss and about 75.65 events per year; wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $163K in expected annual loss and about 0.01 events per year; and hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $273K in expected annual loss and about 6.53 events per year. Across all hazards, FEMA estimates $2M in expected annual loss for a population of 1K.
Beyond physical exposure, Throckmorton County has a medium social vulnerability rating (how susceptible the population is to harm) and a very high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The federal record bears this out: Throckmorton County has received 20 federal disaster declarations since 1978, including 4 for flood events and 4 for severe storm events. The most recent was Severe Winter Storms (severe ice storm), declared in February 2021.
