Natural Hazard Profile: Petersburg, Virginia

Located along the mid-Atlantic coast in Dinwiddie County, Petersburg is a city of approximately 42,012 residents. The humid subtropical climate that characterizes this part of Virginia — marked by hot, humid summers and four distinct seasons — directly influences the types and severity of natural hazards present, making Petersburg a community where hazard awareness has real practical value.

Petersburg's overall natural disaster risk is rated 4.7/10 (Moderate) by FEMA's National Risk Index. Prolonged drought is the primary hazard risk, shaped by low annual rainfall, high evaporation rates, and increasing temperature trends that deepen and lengthen dry periods. Secondary hazards include hurricane and earthquake.

The hazard distribution here is led by drought and hurricane, as measured by FEMA across Dinwiddie County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Petersburg 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 drought is recommended.
