Risk Overview
Tensas Parish carries a very low composite natural disaster risk, with a National Risk Index score of 14.5 out of 100 — placing it in the 15th 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 — $926K in expected annual loss and about 16.23 events per year; hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $371K in expected annual loss and about 0.07 events per year; and hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $237K in expected annual loss and about 3.26 events per year. Across all hazards, FEMA estimates $4M in expected annual loss for a population of 4K.
Beyond physical exposure, Tensas Parish has a very 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.
The federal record bears this out: Tensas Parish has received 29 federal disaster declarations since 1973, including 16 for hurricane events and 3 for flood events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.
Among 64 Louisiana counties, Tensas Parish ranks #62 for overall natural disaster risk.
