Hurricane tops the risk list, and FEMA has declared South Carolina a disaster area 51 times since 1953. Here's what to prepare for — and how.
South Carolina sits at the intersection of multiple serious hazard corridors, making disaster preparedness a year-round priority for its nearly five million residents. The state's long Atlantic coastline and low-lying coastal plain put it squarely in the path of Atlantic hurricanes, which account for the single largest share of its 29 major federal disaster declarations. Hurricane Hugo in 1989 remains the benchmark catastrophe: it made landfall near McClellanville as a Category 4 storm, killed 35 people in the state, and caused roughly $6 billion in damage, devastating coastal communities and stripping forests across the Midlands. Hurricane Floyd in 1999 brought a different kind of destruction, triggering catastrophic inland flooding that swamped rivers across the Pee Dee and Lowcountry regions. More recently, the October 2015 historic rainfall event — sometimes called a '1,000-year flood' — dropped more than two feet of rain in parts of the state over a single weekend, breaching dozens of dams and killing at least 19 people. Tornadoes pose a meaningful secondary risk, particularly in the Upstate and Midlands, while extreme heat affects inland counties each summer. Even winter is not benign: a severe winter storm earned a major disaster declaration as recently as 2026. Taken together, this history tells residents that no single season or hazard defines South Carolina's risk — layered, overlapping threats demand an all-hazards approach to personal and community preparedness throughout the entire year.
Hurricanes bring storm surge, wind damage, and flooding that can cut off evacuation routes.
Tornadoes can form within minutes and level a home — identify your safe room now.
Flooding is the most common US disaster — just 6 inches of moving water can knock a person down.
Extreme heat kills more Americans than any other weather event every year.
This low-elevation coastal zone faces the highest hurricane and storm-surge risk in the state, compounded by chronic tidal flooding that worsens with each hurricane season.
Flat terrain and slow-draining rivers make this region especially vulnerable to prolonged inland flooding from tropical systems and heavy rainfall events like those of 1999 and 2015.
Situated where storm systems converge, the Midlands experience significant flood risk along the Congaree and Saluda rivers as well as tornado threats during spring severe-weather outbreaks.
The Upstate sees the state's most frequent tornado activity and faces ice-storm and winter-weather hazards amplified by elevation, especially in the Blue Ridge foothills near the North Carolina border.
This densely populated coastal tourism corridor is exposed to direct hurricane landfalls, dangerous storm surge, and rapid coastal erosion that can cut off evacuation routes.

The state's official emergency management agency — alerts, shelter info, and disaster assistance.
South Carolina residents can receive official emergency alerts through Wireless Emergency Alerts sent automatically to cell phones, NOAA Weather Radio, and their county's local emergency notification system, all coordinated through the South Carolina Emergency Management Division at scemd.org.
What natural disasters is South Carolina most at risk for?
Hurricanes pose the highest risk, driving the majority of South Carolina's major federal disaster declarations. Flooding, tornadoes, and extreme heat represent medium but serious risks, and winter storms have also triggered major declarations. The state's coastal geography and humid subtropical climate make multi-hazard preparedness essential for all residents.
When is hurricane season, and how should South Carolina residents prepare?
The Atlantic hurricane season runs June 1 through November 30, with peak activity in August and September. Residents should build a 72-hour emergency kit, know their county's evacuation zones, and identify a pre-determined inland destination before a storm threatens. Waiting until a warning is issued can mean dangerous traffic delays on evacuation routes.
What should I do if my area experiences flash flooding?
Never attempt to drive through flooded roads — just six inches of moving water can knock a person down, and two feet can carry away most vehicles. Move to higher ground immediately if warned, avoid drainage channels and streams, and monitor SCEMD and local emergency management alerts. Most flood fatalities in South Carolina involve vehicles entering flooded roadways.
Does South Carolina have a statewide emergency alert system residents can sign up for?
Yes. SC Emergency Alert System broadcasts over radio and television, and residents can receive localized warnings through SC Emergency Management Division's partnerships with county-level alert systems. Wireless Emergency Alerts are automatically pushed to cell phones in affected areas. Residents should also enroll in their specific county's notification system for the most targeted local warnings.
