2023 Rolling Fork tornado

On March 18, an upper-level trough was situated across the Western United States. As time progressed, the trough began to progress to the east. By March 20, forecasters at the National Weather Service's Storm Prediction Center were calling attention to "some potential for discrete storms" in Mississippi on March 24 ahead of the cold front, their severity contingent on prior destabilization of the atmosphere. On March 22, the National Weather Service's Storm Prediction Center (SPC) issued a level 3/enhanced risk of severe weather across portions of Louisiana, Arkansas, and Mississippi for supercell thunderstorms capable of large hail, damaging winds, and strong tornadoes (EF2+ on the Enhanced Fujita scale). The enhanced risk was expanded northward the following day, and the original outlined area was upgraded to a level 4/moderate risk.’s Severe Weather Outlook for March 24, 2023|left|218x218pxOn March 24, water vapor imagery showed a potent mid-level trough. Strong mid-level winds between the trough and strong high-pressure area across the Southeastern United States were displaying in models as well. Meanwhile, a quickly deepening low-pressure area was expected to drag a warm front northward, leading to a broad, unstable air mass to its south. Although some reduction in moisture was expected across Mississippi due to drier air aloft and warm surface temperatures into the 80s Fahrenheit, continued advection of moist air from the Gulf of Mexico seemed supportive of dewpoints in the upper 60s and lower 70's across Louisiana, Arkansas, and Mississippi by the evening hours. Thus, mixed-layer convective available potential energy was expected to rise into the 1,500–2,000 J/kg range. Forecasters initially thought that strong forcing of ascent across Arkansas would lead to an organized squall line capable of both tornadoes and damaging winds, whereas more discrete supercells would be possible farther south, particularly along north–south oriented confluence bands in the open warm sector. The tornado threat relied on the amount of wind shear in the lower levels, which would aid in sustaining supercells. Storm development from Jackson, Mississippi, launched less than an hour before the EF4 tornado began A tornado watch was issued at 5:15 p.m. Central Daylight Time (UTC−5) for portions of eastern Arkansas, northeastern Louisiana, central and northern Mississippi, and western Tennessee. The watch mentioned the possibility of several strong to intense tornadoes with persistent supercells. Clusters of storms evolved along the confluence bands in conjunction with improving wind shear profiles. However, given their displacement from the surface low and better forcing, there was some uncertainty as to whether they would become better organized. A strengthening low-level jet and surface moisture increased confidence in the maturation of these cells, but tornadic development had not yet begun in the area as of 00:00 UTC. At their 01:00 UTC outlook, the SPC lowered the probability of tornadoes to a 10% (significant) tornado area, thus downgrading the moderate risk to an enhanced risk. The SPC cited weaker than expected instability in the area, with increased confidence in only limited buoyancy developing. However, the same update noted that "a couple of longer-track supercells" and "a few strong tornadoes" remained possible. while the EF4 tornado was ongoing As the update was being issued, a strong supercell evolved near the Louisiana-Mississippi border. By 7:57 pm. CDT, a strong velocity couplet formed at the base of the supercell, which then produced what would become this long-tracked violent EF4 tornado, and at 8:04 pm, as the storm approached the town of Rolling Fork, a tornado emergency was placed. Afterwards, the tornado struck Rolling Fork, Midnight, and Silver City, inflicting catastrophic damage and causing over a dozen fatalities. While the violent EF4 tornado was on the ground, Harry Weinman, a forecaster at the SPC, issued a special meso-gamma mesoscale discussion for the tornado. The discussion concluded by noting that the downstream atmospheric environment would allow the storm producing the violent EF4 tornado to persist for 30 to 60 minutes. ==Tornado summary==

Formation The storm that spawned the tornado first developed as a cluster of storms in northeastern Louisiana between 5:30 pm and 6:30 pm CDT and tracked northeastward. This cluster remained disorganized until they approached the Mississippi River, at which point a more favorable low-level jet allowed them to organize into a dangerous supercell thunderstorm rapidly. At 7:33 pm CDT, the National Weather Service in Jackson, Mississippi, issued a severe thunderstorm warning for the strengthening supercell with the threat being for the possibility of 60 mph wind gusts. Shortly after that, the supercell developed a mesocyclone that quickly intensified as it continued swiftly northeastward through Caldwell Parish, which prompted the issuance of a tornado warning at 7:45 pm CDT. A second tornado warning for areas downstream of the first warning, including Rolling Fork, was issued shortly afterwards at 7:53 pm CDT after the supercell crossed the Mississippi River. Four minutes later, the storm spawned the violent tornado that struck Rolling Fork. After touching down, the tornado caused EF1 damage to trees and snapped a small wooden power pole, with two barns also suffering minor damage as it crossed Grant Road before moving through the Steele Bayou Canal and into Sharkey County, causing sporadic tree damage, with some trees being uprooted. Four minutes before crossing the county line, the first report confirming the tornado's existence came at 7:58 pm CDT near Willett Road southeast of Mayersville. Rolling Fork As the tornado entered Rolling Fork on the southwest side of town, it continued to produce up to high-end EF3 damage as it moved through residential areas, although it began to undergo a slow weakening trend as it continued northeastward. Many houses sustained major structural damage with roofs completely removed and exterior walls destroyed, and a few were leveled. Manufactured homes were obliterated, debris was scattered throughout the area, and the Sharkey Issaquena Hospital sustained damage to its exterior. A Farm Bureau Insurance building and Britton Furniture were also destroyed in this area. In addition to the structural damage, many vehicles were thrown through the air and left badly mangled, and numerous large trees in and around Rolling Fork were denuded and debarked, with a few of them stripped clean of all bark. Radar from the National Weather Service indicated a debris signature that extended above Earth's surface as the tornado passed through Rolling Fork. The supercell would go on to produce two additional long-tracked, deadly EF3 tornadoes as it continued northeastward through Mississippi. In the interview, Poole stated: Poole was referring to the flower shop on Walnut Street, which received a damage rating of high-end EF4 with winds of after it was leveled and partially swept away. According to the Damage Assessment Toolkit (DAT), the structure was built in the 1950s as a house with few interior walls and a low-sloping gabled roof. The building ended up being on the southeast side of the track of the tornado, with the southeast-facing gable wall being directly in line with the inflow going into the storm. Thus, despite being over from the center of the tornado, which at the time was crossing Mulberry Street, the structure was not able to withstand the massive amount of wind pressure and was violently destroyed. The neighboring building, which was a small salon, also had a gable roof, albeit at a much steeper angle. It was only leveled and not swept away, and received a high-end EF3 rating with winds of . Additionally, the building next to that one, which was a law office with a more wind-resistant hip roof, had exterior walls knocked down and its roof removed, but was otherwise left standing; this damage received an EF3 rating with winds of . ==Aftermath==

Although the initial warning for Rolling Fork was issued roughly ten minutes before the tornado struck the town, many residents stated that they did not receive any warning due to the cell service being down, the tornado sirens not going off, and the fast speed of the tornado. As a result, the tornado's arrival caught many people off guard with some of them not even knowing what had happened. Additionally, there are no public shelters in the town nor are there any in the rest of the Sharkey County and the surrounding counties. Thus, the residents who somehow did receive a warning were forced to take shelter within their homes and mobile homes, which proved to be inadequate. Preliminary information from the National Weather Service in Jackson, Mississippi indicated that over 78% of the city of Rolling Fork and over 96% of Silver City sustained some level of damage from the tornado, with at least 300 homes sustaining damage in Rolling Fork. Rolling Fork's funeral director and mayor, Eldridge Walker, said on March 27 that search-and-rescue efforts were "pretty close" to finished and authorities believed that everyone had been accounted for. Following major damage to the Sharkey Issaquena Community Hospital and the Delta Health Center, both based in Rolling Fork, the University of Mississippi Medical Center partnered with state agencies to establish a temporary field hospital at the town's National Guard Armory. The Mississippi Emergency Management Agency (MEMA) contracted with the Red Cross to provide survivors with meals and lodging in hotel rooms for up to six months. By April 11, Mayor Walker said that 500 people—approximately a third of the town's population—remained displaced. To dispose of debris and waste from the tornado's damage, Sharkey County established a burn site on the town's outskirts. On April 10 alone, 260 truckloads of debris made the trip to the burn site. Influencer and YouTuber Ryan Hall, Y'all raised $120,000 through social media to give generators out after the storm. Alejandro Mayorkas and Governor Reeves touring the damage in Rolling Fork on March 26 The Mississippi Insurance Department stated that insured losses from the tornado were near $100 million (2023 USD), with uninsured losses likely even higher. Political response Both state and national politicians responded to the devastation in Mississippi. On March 25, Governor of Mississippi Tate Reeves declared a state of emergency in Sharkey, Humphreys, Carroll, and Monroe counties. Governor Reeves's request for a major disaster declaration was granted by President Joe Biden on March 26. President Biden visited Rolling Fork on March 31 and announced that the federal government would fully cover the cost of the cleanup. The Mississippi state legislature also later approved approximately $18.5 million in tornado relief funds. ==See also==
