Risk Overview
Overall natural disaster risk in Spartanburg County is medium, with a National Risk Index score of 90.6 out of 100 — placing it in the 91st national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
The county's risk is driven primarily by ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Very High risk — $4M in expected annual loss and about 1.93 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at Very High risk — $2M in expected annual loss and about 53.85 events per year; and cold wave (prolonged spells of dangerously low temperatures) at High risk — $10M in expected annual loss and about 0.26 events per year. Across all hazards, FEMA estimates $89M in expected annual loss for a population of 327K.
Beyond physical exposure, Spartanburg County has a low social vulnerability rating (how susceptible the population is to harm) and a medium community resilience rating (its capacity to prepare for and recover from disasters). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
The federal record bears this out: Spartanburg County has received 25 federal disaster declarations since 1977, including 11 for hurricane events and 3 for severe storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 46 South Carolina counties, Spartanburg County ranks #10 for overall natural disaster risk.
