Risk Overview

About Natural Disaster Risk in Warren County, Virginia

Warren's risk slightly below national

Warren County's composite risk score of 31.58 earns a Very Low national rating, placing it roughly near typical U.S. county exposure levels. The county benefits from moderate overall disaster risk despite some localized hazard concentrations.

Close to Virginia's average risk

Warren County scores 31.58 against Virginia's state average of 33.27, making it nearly representative of statewide disaster exposure. The county sits squarely in Virginia's middle range for natural hazard vulnerability.

Riskier than Surry, safer than Tazewell

Warren (31.58) faces higher exposure than Surry County (4.71) and Sussex County (13.23) but substantially less than Tazewell County (60.18). Among regional peers, Warren represents moderate rather than extreme risk.

Flooding and earthquakes lead concerns

Warren residents face elevated flood risk (55.69) and earthquake exposure (45.17), the county's primary hazards. Hurricane risk (59.91) also merits attention, while wildfire (36.42) and tornado (24.65) risks remain secondary.

Standard coverage plus flood protection

Warren County homeowners should maintain standard homeowners insurance and consider separate flood coverage given the county's 55.69 flood risk score. Earthquake insurance may also merit evaluation depending on property location and personal risk tolerance.

Risk Advisory: Warren County

Risk Verdict

Warren County's overall natural disaster score at the 32th percentile puts it well below the national median for hazard exposure. Being ranked at the 32th percentile nationally is an advantage for Warren County — it means fewer statistically likely events, though basic readiness ensures households are covered when exceptions occur.

Hazard Breakdown

Hurricane risk is Warren County's dominant natural hazard, ranked at the 60th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 56th percentile nationally. Additional tracked hazards include earthquake (45th percentile), wildfire (36th percentile), tornado (25th percentile).

Preparedness Context

Hurricane exposure at the 60th percentile nationally makes Warren County a county where pre-season preparedness — not storm-day preparation — determines outcomes. Warren County evacuation decisions under a watch or warning benefit from prior planning, not routes improvised under time pressure. Warren County's flood exposure at the 56th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Warren County residents benefit from registering with the county's special-needs evacuation registry if household members have mobility limitations, require electricity-dependent medical equipment, or cannot self-evacuate — registration in advance of storm season is required.

Regional Context

Warren County's risk score is broadly comparable to the Virginia county average, with a 1.7-point gap that places the county near the center of the state's hazard distribution.
