5:44 AM2 NE Holtamville - 3 ENE Holtamville A weak EF-0 tornado touched down in the Nicholsville Community in far southern Marengo County. The tornado began roughly just to the northwest of Crystal Lane. Several trees were uprooted or snapped as the tornado crossed Crystal Lane. A barn then sustained significant roof damage, where pieces of the metal roof were thrown about. Additional trees were snapped and uprooted as the tornado crossed County Road 87 and Nicholsville Road. The most significant damage occurred along Nicholsville Road where a portable metal carport was turned upside down, and two large pine trees were snapped. A large barn sustained significant roof damage very close to where the pine trees were snapped. Pieces of the metal roof were thrown at least 100 yards across a field to the east of the barn. A few trees were snapped or had a few large limbs broken off across the field east of Nicholsville Road. The estimated ending point of the tornado was at this location, as no further damage was found to the east. Start: 32.0121/-87.9099 End: 32.0095/-87.8970
NWS EF Scale: F0
The National Weather Service surveyed damage in northern Marengo County and determined the damage was consistent with an EF1 tornado, with maximum sustained winds near 100 mph. The tornado began near the intersection of U.S. Highway 43 and County Road 54 where damage to cedar trees was observed. The tornado continued east through a heavily forested area and crossed French Creek. Tree damage was observed along County Road 1. The tornado moved further east crossing Alabama Highway 69 where, on the north side, a large tree crushed the south side of a single wide mobile home. Further south, on the south side of the path, near Windsor Drive and Alabama Highway 69, a large farm equipment building lost its roof and walls while wooden supports remained intact. Two mobile homes nearby sustained minor damage to their roofs and siding on the south side. A recreational camper was blown over and crushed a vehicle. Trees were uprooted and split in the vicinity. The tornado pushed east, paralleling Windsor Drive, and caused additional damage to trees that were either uprooted or split. The damage peaked where a single wide mobile home was lofted and blown to the northeast about 30 feet from its original position. The mobile home was less than a year old but appeared to lack any substantial anchoring system. The walls and roof were completely torn away from the floor base and nearly all of the contents were deposited downwind. This appears to be the climax of the tornado's intensity, and winds were estimated to be near 100 mph. To the south of the mobile home's original position was a metal barn that collapsed and destroyed. The tornado made a slight turn to the northeast where it caused damage to an agricultural crop sprinkler system and snapped a power pole along Allenville Road. It then crossed U.S. Highway 80 and damaged two road signs and caused timber damage. The tornado continued northeast and crossed into Hale County near Cottonwood Creek.
A line of thunderstorms moved across Central Alabama during the early morning hours of Wednesday, February 7, 2018. Supercells embedded within the line were responsible for producing large hail, damaging winds, and several tornadoes. Severe weather was not anticipated as most model guidance indicated insufficient instability and wind shear for the development of supercells, tornadoes and other severe convective hazards. Even so, a marginal risk was highlighted for the western and southern portions of Central Alabama. The storms exhibited organization and frequent lightning, indicators that instability was likely higher than expected. The radar signatures were marginal at best and therefore, only a few Severe Thunderstorm Warnings were issued during the event.
