Natural Disaster Risk in Manchester

Natural Hazard Profile: Manchester, New Hampshire

Located along the northeastern Atlantic Seaboard in Hillsborough County, Manchester is a city of approximately 37,775 residents. The humid continental climate that characterizes this part of New Hampshire — marked by long, cold winters and brief, warm summers — directly influences the types and severity of natural hazards present, making Manchester a community where hazard awareness has real practical value.

Manchester's overall natural disaster risk is rated 7.7/10 (High) by FEMA's National Risk Index. The area faces significant ice storm exposure, where the thermal profile of the atmosphere during winter storms frequently delivers freezing rain rather than snow. Secondary hazards include hurricane and lightning.

Relative to other U.S. communities, Manchester's natural disaster risk is well above the U.S. national average of 4.5/10, slightly above the 6.2/10 state average. The hazard distribution here is led by ice storm and hurricane, as measured by FEMA across Hillsborough County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Manchester's high risk designation reflects meaningful exposure to natural hazards. Residents should verify that their insurance covers the area's primary risks, prepare a family emergency plan, and stay informed about seasonal hazard peaks through local weather and emergency management services.
