Tornadoes in Illinois, April 15, 1998

A severe thunderstorm, which originated in eastern Missouri, travelled to the east across southern Illinois. It produced numerous tornadoes. When it moved into our county warning area, it produced two tornadoes over Clay County. The first tornado touched down 3 miles west southwest of Flora. As it travelled to the northeast it destroyed a set of crossing signals along a set of railroad tracks. It moved parallel to the tracks and on the west edge of Flora it blew 60 to 70 cars of a moving CSX freight train off the tracks. No injuries were reported with the train crew or anyone nearby. At this point the tornado was F2 intensity. Most of the tornado track through Flora stayed south of the railroad tracks. In this area most of the structural damage to frame houses was relatively minor with roof/siding damage the most common. A few homes totally lost roofs, garages/storage sheds were destroyed, and one unanchored mobile home was destroyed and landed about 100 feet from its foundation. Three occupants sustained minor injuries. Several vehicles in the area were damaged from falling trees and debris. The tornado briefly lifted and came down again on the east side of town. It damaged or destroyed 40 to 50 condominiums, which was due more to a result of poor construction techniques rather than wind speed. Roof structures did not survive, with the rafters only consisting of 2x4s. The tornado was rated F1 in this area. After hitting the condominium complex, the tornado caused light damage to an industrial park with power poles down and 10 businesses sustaining damage. From there the damage was light, mainly to trees. Two miles northwest of Clay City, the tornado overturned a mobile home before lifting. At about the same time, half a mile to the north of the first tornado, another tornado formed and touched down. It destroyed a mobile home (F2 intensity) and then travelled to the northeast causing spotty damage, mainly to trees. It destroyed a shed 5 miles north of Olney (Richland County) before lifting and dissipating. In total 8 people sustained minor injuries. Damage in Clay County was estimated around $2.2 million and no damage estimate was available for Richland County.
