056 NOUS44 KBMX 292350 PNSBMX ALZ011>015-017>050-301200- Public Information Statement National Weather Service Birmingham AL 650 PM CDT Sat Aug 29 2020 ...NWS DAMAGE SURVEY FOR 08/28/20 TORNADO EVENT... .OVERVIEW... On the afternoon of Aug 28 2020, Tropical Depression Laura and its remnants moved eastward across the Tennessee and Ohio Valleys with a trailing surface boundary across portions of the Deep South. An abundance of tropical moisture coincided with areas of diurnal heating to promote an unstable atmosphere which also interacted with areas of favorable low-level and deep-layer wind shear. As a result, an environment favorable for the development of strong to severe thunderstorms established across a good portion of the Mid to Deep South, including Central Alabama. Strong to severe thunderstorms developed in the vicinity of southern Tennessee and northern Mississippi which tracked generally eastward during the mid afternoon, impacting various areas of northwest Central Alabama. Damaging straight-line winds produced several areas of tree damage as a line of thunderstorms moved across these areas. Additionally, two low-topped supercell thunderstorms moved ahead of this line and generally east-northeastward into Winston County in the late afternoon. These rotating thunderstorms were able to re-intensify and went on to produce two tornadoes, both of EF-1 strength, with the first near the Grayson and Moreland area, and the second in the Double Springs area of north and central Winston County. .TORNADO #1 Moreland Tornado (Winston County)... Rating: EF-1 Estimated Peak Wind: 105 mph Path Length /statute/: 8.75 miles Path Width /maximum/: 325 yards Fatalities: 0 Injuries: 0 Start Date: Aug 28 2020 Start Time: 4:02 PM CDT Start Location: 3 SE Ashridge Start Lat/Lon: 34.2030/-87.4283 End Date: Aug 28 2020 End Time: 4:18 PM CDT End Location: 2 NNE Moreland End Lat/Lon: 34.2670/-87.2974 The tornado developed in a wooded, uninhabited area east of County Road 195 and moved northeast, crossing County Road 6 near Sandy Creek where it caused minor timber damage. The tornado caused minor damage to the roof of a chicken house just off of County Road 415. The tornado continued northeast where it approached Highway 33 west of Moreland. The tornado caused notable timber damage as it crossed Highway 33 then it continues northeast. The tornado moved across County Road 3163 where it removed sheathing from under a manufactured home, destroyed a small outbuilding, and removed portions of siding and sheathing from a manufactured home. The tornado then crossed County Road 63 or Cheatam Road where it removed a portion of the roof from a manufactured home, damaged two garage doors, and blew out a window of a outdoor storage building. A small portion of this structure suffered some minor exterior wall relocation from the slab but it was found that the wall was anchored by nailing to the concrete slab. The tornado continued northeast before dissipating in wooded, uninhabited terrain near Collier Creek. .TORNADO #2 Double Springs Tornado (Winston County)... Rating: EF-1 Estimated Peak Wind: 95 mph Path Length /statute/: 2.56 miles Path Width /maximum/: 100 yards Fatalities: 0 Injuries: 0 Start Date: Aug 28 2020 Start Time: 4:36 PM CDT Start Location: 1 NNE Winston Free State Barn Start Lat/Lon: 34.1684/-87.4100 End Date: Aug 28 2020 End Time: 4:41 PM CDT End Location: 2 NE Houston Recreational Area End Lat/Lon: 34.1698/-87.3654 The tornado developed near a mobile home manufacturing facility where it peeled portions of sheet metal from the roof of the building, removed some skirting from a modular building and blew out two windows on a vehicle. The tornado then crossed Highway 33 where it remained just north of County Road 24 and remaining to the north of the Winston County School complex and transportation lot. The tornado continued east through wooded, uninhabited and inaccessible area. The tornado was found to have dissipated before reaching County Road 2 where there was no observable damage. The National Weather Service would like to thank Winston County EMA for their assistance in these damage assessments. EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories. EF0...Weak......65 to 85 mph EF1...Weak......86 to 110 mph EF2...Strong....111 to 135 mph EF3...Strong....136 to 165 mph EF4...Violent...166 to 200 mph EF5...Violent...>200 mph Note: The information in this statement is preliminary and subject to change pending final review of the event and publication in NWS Storm Data. $$ Sizemore/Holmes/DeBlock
