Risk Overview
Overall natural disaster risk in Wyoming County is low, with a National Risk Index score of 44.8 out of 100 — placing it in the 45th 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 Wyoming County's expected losses come from landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $7K in expected annual loss and about 0.53 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Low risk — $12M in expected annual loss and about 1.43 events per year; and hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $214K in expected annual loss and about 0.03 events per year. Across all hazards, FEMA estimates $14M in expected annual loss for a population of 26K.
Beyond physical exposure, Wyoming County has a medium social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Wyoming County has received 27 federal disaster declarations since 1972, including 9 for severe storm events and 7 for hurricane events. The most recent was Tropical Storm Debby (tropical storm), declared in September 2024.
Among 67 Pennsylvania counties, Wyoming County ranks #59 for overall natural disaster risk.
