Risk Overview

About Natural Disaster Risk in Lycoming County, Pennsylvania

Lycoming's risk sits above the nation

With a composite risk score of 79.58, Lycoming County faces above-average natural disaster exposure compared to U.S. counties overall. The county earned a "Relatively Low" risk rating, meaning its hazards are manageable with proper preparation. However, residents should understand that this score still reflects meaningful flood and hurricane vulnerabilities.

Above average for Pennsylvania

Lycoming's risk score of 79.58 exceeds Pennsylvania's state average of 67.45, placing it among the state's higher-risk counties. This elevated ranking reflects the county's significant flood exposure, which scores 88.99 statewide. Despite ranking above peers, Lycoming's "Relatively Low" rating indicates manageable risk with proper preparation.

Riskier than nearby counties

Lycoming County's risk score of 79.58 exceeds neighboring Mifflin County (69.27) and significantly outpaces McKean County (53.78) to the north. Within the region, only Monroe County (85.08) and Northampton County (90.01) face comparable or greater disaster exposure. Lycoming residents benefit from proximity to lower-risk areas but should recognize their higher vulnerability relative to neighboring counties.

Flood and hurricane threats dominate

Flooding poses Lycoming's most significant hazard, with a risk score of 88.99—the county's highest and well above state average. Hurricane exposure ranks second at 75.05, reflecting the region's vulnerability to tropical systems tracking inland from the Atlantic. Together, these water-related hazards account for the majority of the county's overall composite risk.

Flood insurance is essential here

Lycoming County's flood risk score of 88.99 makes comprehensive flood insurance critical—standard homeowners policies do not cover flood damage. Review your property's elevation and proximity to the Susquehanna River and its tributaries; even moderate rainfall can overwhelm drainage systems. Consider also fortifying your roof and securing outdoor items ahead of hurricane season.

Risk Advisory: Lycoming County

Risk Verdict

Lycoming County's FEMA risk score places it at the 80th percentile nationally, indicating lower-than-typical exposure for a U.S. county. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Lycoming County residents.

Hazard Breakdown

Flood risk is Lycoming County's dominant natural hazard, ranked at the 89th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 75th percentile nationally. Additional tracked hazards include tornado (50th percentile), earthquake (48th percentile), wildfire (27th percentile).

Preparedness Context

At the 89th percentile nationally for flood risk, Lycoming 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 75th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A tested family preparedness plan specific to Lycoming 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

The Pennsylvania county average is 12.1 composite points below Lycoming County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
