Risk Overview

FEMA's National Risk Index rates Monroe County at low composite risk, with a National Risk Index score of 48.7 out of 100 — placing it in the 49th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.

Most of Monroe County's expected losses come from hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Medium risk — $4M in expected annual loss and about 0.14 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at Medium risk — $524K in expected annual loss and about 76.68 events per year; and drought (extended dry periods that stress water supplies and agriculture) at Low risk — $203K in expected annual loss and about 15.17 events per year. Across all hazards, FEMA estimates $10M in expected annual loss for a population of 20K.

Beyond physical exposure, Monroe County 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: Monroe County has received 26 federal disaster declarations since 1975, including 15 for hurricane events and 5 for severe storm events. The most recent was Hurricane Helene (hurricane), declared in September 2024.

Among 67 Alabama counties, Monroe County ranks #44 for overall natural disaster risk.
