On March 2, 2012, a powerful, long-lived and deadly tornado tore across eastern Kentucky and western West Virginia in the eastern United States, through the Cumberland and Allegheny Plateau regions of the western Appalachian Mountains. It was one of several tornadoes rated EF3 on the Enhanced Fujita scale during a large and deadly tornado outbreak across the Ohio River Valley. During the event, the very long-track tornado covered the longest distance of any tornado during the outbreak, and subsequently of the entire 2012 season.United States Tornadoes of 2012 National Weather Service. Retrieved 2013-08-02 The storm tracked through portions of Menifee, Morgan, Lawrence, and Johnson Counties in Kentucky, to Wayne and Lincoln Counties in West Virginia. Along its path, the tornado most notably impacted the city of West Liberty, Kentucky, in central Morgan County.The National Oceanic and Atmospheric Administration's finalized damage survey by county:
The 2012 West Liberty tornado, was among the few, especially strong tornadoes to track across mountainous regions, debunking the myth that tornadoes do not track over such geography. It was also the first time an intense (F3/EF3+) tornado struck the regional county warning area of the National Weather Service in Jackson, Kentucky, with the last such tornado occurring back in 1988 where the city of Middlesboro, Kentucky, was hit. 10 people were killed by the tornado, with 118 others injured across six different counties in Kentucky and West Virginia, causing approximately $81,475,000 (2012 USD) in total damages. The tornado tracked a path length of long and wide at its largest in Morgan County, Kentucky, along its 88-minute lifespan.
Meteorological synoptics Episode narrative
One day prior on March 1, 2012, at approximately 12:30 PM EST (17:30 UTC), the NOAA Storm Prediction Center (SPC) issued a large, 45% hatched and level 4/5 moderate risk area for severe weather across the eastern United States. This large risk spanned across northern Mississippi and Alabama, into central Tennessee and Kentucky, towards southern Indiana and Ohio the following day on the 2nd. A very large mid- and upper level trough was stationed in northern Arkansas and southern Missouri, towards the Columbus, Ohio area. The trough moved slowly eastward from its position in the Ozark Mountains, transporting a belt of fast southwesterly winds to the southeastern side of the storm system. This overlapped with a highly sheared region, resulting in a possibility of tornadic supercells forming and tornadoes in general, some strong per the SPC.
The following day on March 2 at around 8:00 PM EST (13:00 UTC), the SPC issued a Public Severe Weather Outlook (PWO), concerning a more hazardous risk for significant (EF2+) tornadoes than what was expected the day prior. A level 5/5 high risk, which corresponded to a 30% hatched tornado risk, was put in place over central Kentucky and north-central Tennessee. The moderate risk area widened to include portions of southeastern Illinois, northwestern Georgia and the western Virginias. Alongside the main tornado risk, 45% hatched hail and damaging wind risks were issued over parts of the Ohio and Tennessee River Valleys. At 11:30 PM EST (16:30 UTC), the SPC adjusted the outlooks to include southern Indiana and Ohio in the high risk. At the same time, the moderate risk extended more westward, with most of northern Mississippi encompassed by it but also a small portion in eastern Missouri. The 45% hatched wind risk extended south to northern Alabama and Georgia, where as the 45% hatched hail risk moved westward, with northern Mississippi included. The strong upper-level trough with a vorticity center moved from northern Missouri to the Ohio River Valley area. Strong wind shear with the trough created a large and expanding unstable air mass, which then overlapped a massive region across parts of the river valley and southern states, conducive for a widespread and potentially destructive tornado outbreak.
Event narrative On the morning of March 2, 2012, around 10:30 AM EST (15:30 UTC) a tornado watch was issued by the National Weather Service across east-central Tennessee, northern Alabama and northwestern Georgia. An initial squall line that formed along the Kansas–Missouri border moved eastward across the state and towards the Tennessee/Ohio River Valley area. Some of these storms within the line showed signs of rotation. These morning storms, including one that was responsible for a damaging EF3 tornado that impacted the northern Huntsville, Alabama metropolitan area, were associated with an incoming warm front that was linked to a low pressure area, located north at the Great Lakes. After many strong tornadoes occurred throughout the warm sector, the latest and final PDS tornado watch was issued at approximately 4:20 PM EST (21:20 UTC) that covered parts of Kentucky, Ohio, West Virginia and Virginia. Many of these supercells that had a history of producing destructive tornadoes, moved towards the Appalachian Mountains later into the evening. High vertical wind shear values were present within the warm sector of the expanding extratropical cyclone, giving way for storms to produce strong tornadoes. One of these supercells at this time would be responsible for the EF3 tornado that struck West Liberty, Kentucky soon after.
Tornado summary Beginning phases
At 5:39 PM EST (22:39 UTC) the tornado touched down along Tarr Ridge, approximately southwest of Mariba or due south of Frenchburg, in south-central Menifee County, Kentucky. Along KY 77, the tornado impacted a few residences it encroached over, causing extensive amounts of damage to some. It continued eastwards after causing destruction to some homes along Trimble Bend Road, as it was passing south of Denniston before then approaching areas south of Wellington. South-southwest of the community along Opossum Hollow Road, the tornado struck several residences, with one home being nearly completely destroyed, leaving only the basement remaining. After crossing over US 460, the tornado exited Menifee County where it killed two people. An additional but indirect fatality occurred as one person fell to their death off a staircase during clean-up efforts in the area. Approximately $2,000,000 (2012 USD) in damages were inflicted within Menifee County.See "Event Details for Menifee County, Kentucky"
Impact on West Liberty
Prior to the tornado's formation, at 5:38 PM EST (22:38 UTC), a tornado warning was issued by the National Weather Service office in Jackson for parts of Morgan, Magoffin, Johnson, Floyd, Breathitt, Lee and Wolfe Counties. The tornado then entered western Morgan County, northwest of Ezel at 5:46 PM EST (22:46 UTC). Spending the following 12 minutes traversing across the hilly terrain, the storm impacted or passed by homes before making a hit on West Liberty at 5:58 PM EST (22:58 UTC). Entering into the city through Dixie Lane, the tornado would level several buildings located along KY 7 and Prestonsburg Street at EF3 intensity, such as the 105-year old courthouse that was built back in 1907. The 100-year old West Liberty United Methodist and Christian churches in the downtown area were destroyed as well. A Great Depression-era Works Progress Administration community center was demolished as the tornado tracked through the city. Much of the downtown area was left littered with debris of buildings, as the tornado continued paralleling Prestonsburg Street eastward.See "Event Details for Morgan County, Kentucky"
After leaving West Liberty to the northeast, the tornado impacted a few rural residences, causing extensive damage to them. At the same time, the tornado downed thousands of trees around the area east of West Liberty. Within Morgan County, the tornado had estimated winds of , and grew to its maximum width of , and caused $75,000,000 (2012 USD) in damages throughout the county, the most out of six counties impacted.
Rural track through Appalachia
Around 6:10 PM EST (23:10 UTC), the tornado exited Morgan County, and entered the regional county warning area of the National Weather Service in Charleston, West Virginia, into Lawrence County, remaining at EF3 intensity. In portions of the county, the tornado inflicted EF3 damage to two mobile homes along Skaggs Road with winds estimated at . Two people inside these modular residences sustained injuries but survived.See first part of "Event Details for Lawrence County, Kentucky" After traveling through Lawrence County in 3 minutes, the tornado entered Johnson County, back into the county warning area of the Jackson, Kentucky office at 6:13 PM EST (23:13 UTC). The tornado, upon its entry, weakened to EF1 intensity, with homes near Keaton sustaining minor roof damage and numerous trees being downed.See "Event Details for Johnson County, Kentucky" The storm once again entered Lawrence County and the county warning area of the Charleston, West Virginia office near Martha, at 6:18 PM EST (23:18 UTC). Passing to the south of Blaine, the tornado struck the community building of the former city. Passing eastwards in between Blaine and Cordell, the tornado caused EF3 damage to a mobile home along Spencer Branch Road, lifting it off its CMU foundation and slamming into the adjacent hillside. Inside the home, three out of five people, an elderly couple and their 14-year-old granddaughter were later extricated out of the residence. Both the 14-year-old girl and her 65-year-old grandmother were killed, where as the 75-year-old grandfather survived with extreme injuries. The two others survivors were juveniles that were unharmed, and a neighbor nearby survived but suffered from a broken leg. Near Chapman, one family of four hunkered down inside a bathtub to ride out the tornado, ultimately surviving while their house was destroyed. In the Clifford area, the tornado reached its peak strength as mid-range EF3 winds that were estimated at struck and caused severe damage to homes along Rockcastle Creek.See second part of "Event Details for Lawrence County, Kentucky"
The tornado maintained its strength as it entered Wayne County, West Virginia, into the Cabwaylingo State Forest at 6:38 PM EST (23:38 UTC). Many trees were blown down in this section of western Wayne County. Passing near Dunlow, the tornado impacted residences across several hilltops, with one home sustaining low-end EF3 damage from estimated winds of , and at least three vehicles that were damaged in the vicinity. The tornado continued northeast, reaching the Cove Gap and Kiahsville areas and causing more damage to homes. Many residents in this area were attending a funeral of a local at the time and were away when the tornado passed through the East Lynn Lake area, which likely contributed to no reported casualties despite the damage.See "Event Details for Wayne County, West Virginia"
Endpoint The tornado then moved into Lincoln County at around 6:57 PM EST (23:57 UTC), as it weakened to EF1 intensity, with damage being inflicted to trees south of Ranger. After tracking through the county for 10 minutes, the tornado dissipated near Union Gap Road, east of Ranger, West Virginia at 7:07 PM EST (00:07 UTC), after being on the ground for 1 hour and 28 minutes. The tornado tracked a total distance of 84.99 mi (136.78 km) from its start in Menifee County, Kentucky, all the way to Lincoln County, West Virginia..See "Event Details for Lincoln County, West Virginia"
