Residents across central South Carolina found themselves bracing for turbulent weather on Thursday, March 12, 2026, as a series of severe weather alerts swept through the region. According to the National Weather Service (NWS) Columbia SC, a severe thunderstorm warning was initially in place for Clarendon and Sumter counties until noon, but the storms that triggered the alert moved out of the area, allowing the warning to expire. However, the threat was far from over, as a Tornado Watch remained active until 1 p.m. for much of central South Carolina, keeping residents on edge and local officials vigilant.
The morning's weather drama began in earnest at 11:11 a.m., when the NWS issued a fresh alert for strong thunderstorms expected to impact Chesterfield, Kershaw, Lee, and Sumter counties until 11:45 a.m. Doppler radar at that time tracked a line of storms stretching from 6 miles west of Chesterfield to 6 miles east of Cassatt to Mulberry, moving northeast at a brisk 45 mph. The NWS warned, "Gusty winds could knock down tree limbs and blow around unsecured objects," with wind gusts reaching up to 55 mph. The list of potentially affected locations was long, including Sumter, Cheraw, Bishopville, Chesterfield, Cheraw State Park, Northeastern Technical College, Cassatt, Elliott, Cheraw Municipal Airport, Mulberry, Lee State Park, Carolina Sandhills Wildlife Refuge, Sumter County Airport, Mcbee, Mayesville, Society Hill, Lynchburg, Ruby, Patrick, and Bethune. Major highways like Interstate 20 (between mile markers 106 and 125) and Interstate 95 (near mile marker 146) were also under the watchful eye of weather authorities.
As the skies darkened and the wind picked up, the NWS urged South Carolinians to remain alert. "If outdoors, consider seeking shelter inside a building. These storms may intensify, so be certain to monitor local radio stations and available television stations for additional information and possible warnings from the National Weather Service," the agency advised. The Tornado Watch, updated at 11:18 a.m., extended coverage to Chesterfield, Clarendon, Kershaw, Lee, Orangeburg, and Sumter counties, reinforcing the seriousness of the threat and the need for preparedness.
For many, the day’s warnings were a sobering reminder of the unpredictable and sometimes dangerous nature of spring weather in the southeastern United States. Lightning, a frequent companion to these storms, strikes the country approximately 25 million times each year, according to the NWS, with most incidents occurring during the summer. These strikes result in about 20 fatalities annually, underscoring the need for vigilance even when tornadoes are not present. The risk of lightning increases as a thunderstorm approaches, reaching its peak when the storm is directly overhead, and gradually subsides as the system moves away.
To help residents stay safe, the NWS offered a suite of practical tips for navigating lightning hazards. First and foremost, if you hear thunder or see ominous skies, seek shelter in a sturdy building. Once inside, avoid contact with corded phones, electrical equipment, plumbing, and windows or doors. The agency also recommends waiting at least 30 minutes after the last clap of thunder before venturing outdoors again. For those caught outside without access to indoor shelter, the advice is clear: steer clear of open fields, hilltops, and isolated tall trees. In forests, stick to areas with shorter trees. If you’re part of a group, spread out to reduce the risk of current passing between individuals. Campers are urged to pitch tents in valleys or low areas—though tents themselves offer no protection from lightning—and to stay away from water, wet items, and metal objects, which, while not attracting lightning, conduct electricity efficiently.
Driving during severe weather presents its own set of challenges. The NWS recommends switching on headlights—even in daylight—to enhance visibility. Drivers should stick to middle lanes and higher ground, as rainwater tends to accumulate at road edges. Avoiding puddles and flooded areas is crucial; hydroplaning, where a vehicle slides uncontrollably on a thin layer of water, can occur even with a shallow puddle. The NWS breaks down the main contributors to hydroplaning: vehicle speed (the faster you go, the less grip you have), water depth (the deeper the water, the sooner traction is lost), and tire tread depth (worn tires increase the risk). If your vehicle starts to hydroplane, the advice is to ease off the accelerator, steer gently into the skid, and wait for the tires to reconnect with the road before straightening the wheels. Braking should be gentle—use anti-lock brakes normally or pump the brakes gently if your car is older.
Of course, tornadoes present a different set of hazards and require swift, decisive action. The NWS emphasizes that acting quickly is the key to staying safe when a tornado warning is issued. For those indoors, the safest place is a basement, dedicated safe room, or an interior room without windows. Take pets with you if time allows. At workplaces or schools, follow established tornado drill protocols and head to designated shelter areas, steering clear of large open spaces like cafeterias or gymnasiums. Outdoor safety is more complicated; the best option is to seek shelter in a sturdy building immediately. Mobile homes, sheds, and tents are not safe. If you’re in a vehicle and can’t reach shelter, either crouch down inside the car and cover your head or leave the vehicle to find a low-lying area such as a ditch or ravine.
Preparedness doesn’t end with knowing where to shelter. The Federal Emergency Management Agency (FEMA) recommends assembling a basic disaster supplies kit to weather the storm—literally. Essentials include one gallon of water per person per day (for at least three days), a three-day supply of food, cell phone with chargers and backup battery, battery-powered or hand-crank radio, flashlight, first-aid kit, whistle, dust mask, plastic sheeting and duct tape for sheltering, moist towelettes, garbage bags, plastic ties, manual can opener, and local maps. Having these items ready can make a critical difference if disaster strikes and services are disrupted.
Thursday’s wave of warnings and watches across South Carolina served as a vivid reminder of just how quickly conditions can change—and how vital it is to be prepared. Whether it’s heeding the NWS’s advice on lightning, following safe driving practices in heavy rain, or knowing exactly where to go when tornado sirens blare, a little foresight and calm can go a long way toward keeping families and communities safe when the weather turns wild.
