Risk Overview

FEMA's National Risk Index rates Otero County at medium composite risk, with a National Risk Index score of 84.7 out of 100 — placing it in the 85th national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.

Most of Otero County's expected losses come from wildfire (uncontrolled fires that spread across wildland and into communities) at High risk — $12M in expected annual loss and about 0.01 events per year; winter weather (heavy snow, blizzards, and hazardous winter conditions) at High risk — $414K in expected annual loss and about 4.86 events per year; and lightning (electrical discharges from storms that ignite fires and cause casualties) at High risk — $1M in expected annual loss and about 60.95 events per year. Across all hazards, FEMA estimates $43M in expected annual loss for a population of 68K.

Beyond physical exposure, Otero County has a high social vulnerability rating (how susceptible the population is to harm) and a very 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 county's disaster history tells the same story: Otero County has received 24 federal disaster declarations since 1984, including 12 for fire events and 5 for severe storm events. The most recent was Severe Storms, Flooding, and Landslides (flood), declared in July 2025.

Among 33 New Mexico counties, Otero County ranks #7 for overall natural disaster risk.
