Risk Overview
Overall natural disaster risk in Winn Parish is very low, with a National Risk Index score of 29.5 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.
The county's risk is driven primarily by heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at Low risk — $591K in expected annual loss and about 21.68 events per year; hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $247K in expected annual loss and about 0.06 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $90K in expected annual loss and about 1.04 events per year. Across all hazards, FEMA estimates $6M in expected annual loss for a population of 14K.
Beyond physical exposure, Winn Parish has a very high social vulnerability rating (how susceptible the population is to harm) and a medium 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: Winn Parish has received 32 federal disaster declarations since 1983, including 15 for hurricane events and 4 for flood events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.
Among 64 Louisiana counties, Winn Parish ranks #55 for overall natural disaster risk.
