| 3 | February 24, 2012 | Colleton | (EF1) A high shear environment ahead of an approaching cold front and strong upper dynamics set the stage for severe weather across Southeast GA and Southern SC during the afternoon. A few supercells and a line of thunderstorms with small bows and breaks swept through the region to the west of Interstate 95. Record high temperatures occurred preceding the front which allowed for enough instability to develop in the mid to late afternoon hours. A National Weather Service damage survey team confirmed that an EF-1 tornado touched down near Islandton, South Carolina. The tornado initially touched down along Jamison Road and traveled east/northeast before lifting along Highway 63. The worst damage occurred along Forks Road and Jamison Road where the tornado damaged or destroyed several structures. At least 3 mobile homes sustained roof damage and at least 30-35 trees were either completely uprooted or snapped. The tornado also snapped several power poles. The most significant damage occurred around 591 Jamison Road. | 2 | 150 |
| 4 | March 3, 2012 | Richland | (EF0) A squall line pushed through the Midlands, CSRA, and Pee Dee region taking down trees and powerlines. An EF0 tornado touched down just west of Monticello road on the back end of Columbia International University then crossed the intersection of Houston Street and Bishopville Ave. The tornado continued with intermittent touchdown east to Patton Lane. Many trees and large branches were down, some which fell on a mobile home doing minor damage. | 2.54 | 80 |

The tornado continued through a corn field leaving flattened swirls of corn in its wake. | 1.52 | 60 |
| 7 | June 10, 2012 | Newberry | (EF0) solated severe storms produced locally heavy rain with amounts up to 5 inches and a weak tornado. Sheriff conducted a damage survey of the trees down from just east of the airport to I-26. | 1.5 | 50 |
| 8 | June 11, 2012 | Calhoun | (EF0) A couple of supercells producing weak tornadoes developed ahead of an approaching squall line. The squall line also produced heavy rain. SCEG reported several trees and powerlines down from a weak tornado near Cameron. | 1.24 | 50 |
| 9 | June 11, 2012 | Jasper | (EF1) Scattered to numerous thunderstorms developed within a warm and unstable atmosphere along an early afternoon seabreeze and various meso-scale outflow boundaries. A National Weather Service damage survey team evaluated damage that occurred with a severe thunderstorm that moved through portions of central Jasper County Monday afternoon. The team found considerable damage to trees south of Ridgeland with a damage pattern consistent with a tornado.||The tornado touched down just west of Jasper Road between the communities of Okatie and Switzerland and moved rapidly east-northeast before lifting near the intersection of South Carolina Highway 462 and Snake road. The worst damage occurred between Jasper Road and Riley Field Road where the team estimated between 300 and 500 medium to large-size trees were either snapped or uprooted. Some debarking of trees was also noted. This degree of|tree damage was consistent with an ef-1 tornado on the enhanced Fujita scale with winds estimated to be between 85 and 95 mph. | 4.11 | 525 |
| 10 | August 1, 2012 | Charleston | (EF0) With a very weak pressure pattern in place across much of the Southeastern portion of the country, the environment was conducive to the development of waterspouts. A funnel cloud first appeared over Kiawah Island then moved into the waterway east of the bridge on Kiawah Island Parkway. Based on photographs and video taken, it appears that the funnel briefly touched down near the Intracoastal Waterway before dissipating. There were no reports of damage associated with this tornado. | 0.03 | 50 |
