Risk Overview
Overall natural disaster risk in Laurens County is low, with a National Risk Index score of 76.2 out of 100 — placing it in the 76th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in cold wave (prolonged spells of dangerously low temperatures) at High risk — $8M in expected annual loss and about 0.21 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $777K in expected annual loss and about 1.78 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at High risk — $1M in expected annual loss and about 3.99 events per year. Across all hazards, FEMA estimates $27M in expected annual loss for a population of 67K.
Beyond physical exposure, Laurens County has a high social vulnerability rating (how susceptible the population is to harm) and a low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
History supports the rating: Laurens County has received 23 federal disaster declarations since 1977, including 10 for hurricane events and 3 for severe ice storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 46 South Carolina counties, Laurens County ranks #26 for overall natural disaster risk.
