Risk Overview

Overall natural disaster risk in Pittsburg County is low, with a National Risk Index score of 73.3 out of 100 — placing it in the 73rd 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.

Risk here concentrates in ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Very High risk — $1M in expected annual loss and about 1.56 events per year; wildfire (uncontrolled fires that spread across wildland and into communities) at Medium risk — $3M in expected annual loss and about 0.02 events per year; and drought (extended dry periods that stress water supplies and agriculture) at High risk — $2M in expected annual loss and about 29.86 events per year. Across all hazards, FEMA estimates $22M in expected annual loss for a population of 44K.

Beyond physical exposure, Pittsburg 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 county's disaster history tells the same story: Pittsburg County has received 33 federal disaster declarations since 1970, including 16 for severe storm events and 6 for severe ice storm events. The most recent was Severe Storms, Straight-Line Winds, Tornadoes, and Flooding (tornado), declared in April 2024.

Among 77 Oklahoma counties, Pittsburg County ranks #27 for overall natural disaster risk.
