Risk Overview
Overall natural disaster risk in Robertson County is very low, with a National Risk Index score of 29.6 out of 100 — placing it in the 30th 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.
Risk here concentrates in hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $536K in expected annual loss and about 0.06 events per year; drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $309K in expected annual loss and about 40.78 events per year; and tornado (violently rotating columns of air capable of catastrophic local damage) at Low risk — $1M in expected annual loss and about 0.46 events per year. Across all hazards, FEMA estimates $7M in expected annual loss for a population of 17K.
Beyond physical exposure, Robertson County has a high social vulnerability rating (how susceptible the population is to harm) and a low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
History supports the rating: Robertson County has received 18 federal disaster declarations since 1991, including 5 for hurricane events and 3 for fire events. The most recent was Hurricane Beryl (hurricane), declared in July 2024.
Among 254 Texas counties, Robertson County ranks #171 for overall natural disaster risk.
