NWS Confirms EF-0 Tornado Touched Down in Northern Allendale County

The National Weather Service in Charleston confirmed an EF-0 tornado touched down in northern Allendale County on March 12, cutting a path of nearly 3.8 miles near the community of Millett before dissipating. No fatalities or injuries were reported.

The storm announced itself with urgency. At 9:43 a.m., the NWS issued a severe thunderstorm warning for the area, noting that a storm "capable of producing a tornado was located over Millett, moving east at 45 mph." The warning covered the communities of Martin, Millett, Baldock, and Averill and remained in effect until 10 a.m. Severe thunderstorm warnings also covered Fairfax and Sycamore that morning, with reports of wind damage across the region.

The NWS warning carried blunt language about the risks: "Flying debris will be dangerous to those caught without shelter. Mobile homes will be damaged or destroyed. Damage to roofs, windows and vehicles will occur. Tree damage is likely." Residents in mobile homes, outdoors, or in vehicles were urged to reach the closest substantial shelter immediately and move to an interior room on the lowest floor of a well-built building, away from windows.

The EF-0 rating places the tornado at the lowest end of the Enhanced Fujita scale, typically associated with wind speeds between 65 and 85 mph and damage characterized by broken tree branches, shallow-rooted trees knocked over, and minor structural impacts to roofs and windows. A prior NWS survey of an earlier Allendale County EF-0 event documented "sporadic, discontinuous tree damage" as the hallmark of a tornado of this intensity moving through the county's mix of rural roads and woodlands.

The March 12 tornado was not an isolated event. Severe weather swept broadly across South Carolina that period, with the NWS confirming multiple tornadoes across the Midlands and Lowcountry. In the Midlands alone, survey teams confirmed four tornadoes on a Thursday, including a tornadic waterspout over Lake Murray and EF-0 touchdowns northwest of Irmo in Richland County, north of Ridge Spring in Saluda County, and in Bamberg County, where peak winds reached 75 mph.

For Allendale County, one of South Carolina's most rural and economically vulnerable communities, even a weak tornado carries outsized consequences. Power infrastructure, older housing stock, and the prevalence of mobile homes across the county mean that EF-0 conditions can cause damage that takes weeks to address. The NWS warning's explicit mention of mobile home destruction reflects that reality.

Allendale County residents with storm damage are encouraged to contact county emergency management to report impacts and access recovery resources.
