Risk Overview

About Natural Disaster Risk in Allegany County, Maryland

Allegany's risk sits below the national average

With a composite risk score of 58.52, Allegany County ranks in the "Relatively Low" category, performing better than the national average for natural disaster exposure. This score reflects moderate vulnerability across multiple hazard types, with no single threat dominating the county's risk profile.

A safer choice within Maryland

Allegany County's score of 58.52 falls just below Maryland's state average of 60.22, placing it in the lower half of the state's 24 jurisdictions for overall risk. The county benefits from a more balanced hazard distribution compared to coastal neighbors.

Allegany outpaces western county peers

Compared to nearby Carroll County (59.51) and Cecil County (58.56), Allegany ranks similarly, but all three western counties remain safer than Baltimore City (95.01) and Baltimore County (93.99). Allegany's northwestern location shields it from the elevated hurricane and tornado risks facing the state's urban and coastal zones.

Hurricane and flood concerns top Allegany's list

Allegany's highest risk scores come from hurricane exposure (67.67) and flooding (73.63), both elevated relative to the county's overall low rating. Tornado risk (35.75) and earthquake hazard (52.86) pose secondary concerns, while wildfire danger remains minimal at 20.96.

Prepare for water and wind damage

Residents should prioritize flood and wind insurance, especially those in flood-prone areas along streams and rivers. Standard homeowners policies don't cover flood damage, so a separate policy from the National Flood Insurance Program or private insurers is essential for peace of mind.
