South Carolina Hurricane Hazard Profile

Climate-Adjusted Hazard Data · Model Version 1.0

Overview

South Carolina's Atlantic coastline is exposed to hurricane wind and storm surge hazard, with the Charleston and Myrtle Beach metro areas representing the primary exposure concentrations. IBTrACS data shows South Carolina receives direct hurricane landfalls and is frequently affected by storms tracking along the Southeast coast. NOAA SLOSH models indicate significant storm surge potential in the low-lying Charleston harbor.

Notable Historical Events

12018 Hurricane Florence — flooding extended into SC border counties
22016 Hurricane Matthew — 15 fatalities, significant coastal flooding (FEMA DR-4286)
31989 Hurricane Hugo — CAT 4 at Charleston, $7B+ total damage (FEMA DR-843)

Hazard Scoring Approach

CivilSense computes a Climate-Adjusted Hazard Score (0–10) for hurricane hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and peer-reviewed research. All score components are transparent and returned in API responses.

These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
