Risk Overview
About Natural Disaster Risk in Warren County, Pennsylvania
Warren faces moderate-to-high national risk
Warren County scores 65.55 nationally, approaching the higher end of U.S. disaster vulnerability and well above the American average. This positioning indicates residents face substantial natural hazard exposure across multiple hazard types requiring serious preparedness attention.
Slightly below state average within Pennsylvania
Warren County's score of 65.55 falls just below Pennsylvania's average of 67.45, placing it in the relatively low-risk tier statewide despite national positioning. However, the county remains among the more exposed communities within its own state.
Higher risk than most regional peers
Warren County (65.55) carries greater hazard exposure than neighboring Venango County (55.60) and Susquehanna County (53.59), driven primarily by its exceptionally high flood risk of 82.82. Only Washington County among nearby counties exceeds Warren's disaster vulnerability.
Flood is Warren's dominant hazard
Warren County's critical exposure is flood risk at 82.82, among the highest in Pennsylvania and substantially above the state average. Hurricane risk (57.15) and tornado risk (21.95) add secondary concerns, though neither matches the intensity of water-related hazards.
Prioritize flood insurance immediately
Warren County residents must secure dedicated flood insurance given the county's exceptionally high flood risk score of 82.82. Combined with comprehensive homeowners coverage, flood protection is essential for financial security in this high-water-exposure community.

Warren County's FEMA risk score places it at the 66th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.
Hazard Breakdown
Flood risk is Warren County's dominant natural hazard, ranked at the 83th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 57th percentile nationally. Additional tracked hazards include tornado (22th percentile), earthquake (21th percentile), wildfire (12th percentile).
Preparedness Context
At the 83th percentile nationally for flood risk, Warren County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Alongside flooding, hurricane exposure at the 57th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A tested family preparedness plan specific to Warren County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.
Regional Context
Warren County sits within 1.9 composite points of the Pennsylvania state average, suggesting the county's hazard exposure is representative of the broader regional pattern.
