Natural Hazard Profile: Grand Valley, Pennsylvania

Located in the Great Lakes region in Warren County, Grand Valley is a small community of about 515. The humid continental climate that characterizes this part of Pennsylvania — marked by cold winters, warm summers, and four distinct seasons — directly influences the types and severity of natural hazards present, making Grand Valley a community where hazard awareness has real practical value.

FEMA rates Grand Valley's composite natural disaster risk at 4.8 out of 10 — moderate risk. Avalanche risk is the dominant natural hazard, with steep mountain terrain and heavy seasonal snowpack creating conditions for dangerous snow slides in and around the area. Residents should also account for wind and landslide risk in their preparedness planning.

Relative to other U.S. communities, Grand Valley's natural disaster risk is near the U.S. national average of 4.5/10, slightly below the 5.9/10 state average. The hazard distribution here is led by avalanche and wind, as measured by FEMA across Warren County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Grand Valley residents are well-served by maintaining standard preparedness practices — an emergency supply kit, awareness of local hazard seasonality, and insurance that covers the top local risks. Periodic review of coverage for avalanche is recommended.
