2011 Joplin tornado
Overall, the tornado killed 158 people (with an additional three indirect deaths), injured some 1,150 others, and caused damages amounting to a total of $2.8 billion. It was the deadliest tornado to strike the United States since the 1947 Glazier–Higgins–Woodward tornadoes, and the seventh-deadliest overall.
Tornado outbreak of June 13, 1998
In the afternoon and evening of June 13, four supercells which had formed near the dryline over Western Oklahoma entered the central part of the state, two of which produced tornadoes, and two of which only produced strong winds and hail. The first of the two tornado-producing storms produced two tornadoes; the former, which touched down near Longdale, injured a child and caused tree damage, ultimately causing F0 damage. The latter tornado, which was ultimately rated F1, caused roof, window, siding, and porch damage to three houses. It also took off the roof of a barn, destroyed an outbuilding, caused fence damage, and took off the hood of a pickup truck.
The second tornadic supercell produced seven tornadoes. The first two tornadoes touched down near El Reno and caused no damage, earning ratings of F0. The third tornado touched down near Yukon but, as with the other two, caused no damage and was rated F0. A fourth tornado touched down over Lake Hefner in Oklahoma City, eventually causing damage to boats in a dry dock at the Oklahoma City Boat Club. Damage to club facilities and nearby boats was estimated at $250,000. The tornado went on to destroy a storage shed and cause minor roof damage to homes east of Lake Hefner Parkway before it dissipated, having caused only F1 damage. The fifth tornado (rated F1) materialized near NW 84th Street and Walker, going on to displace much of a house's roof decking and uproot street signs. The tornado also damaged vehicles and caused roof damage to houses on 84th, 85th, 86th, 87th, and 88th Streets. The tornado destroyed the western half of a church in this area after it knocked down its walls on three sides and threw part of its roof at a house which resultantly suffered major damage. The sixth tornado, which was anticyclonic, affected the Northwest Oklahoma City/Nichols Hills area. It caused "considerable" damage to a strip mall, unroofed numerous houses, shattered windows, and damaged signs and powerlines. One building saw an exterior wall collapse. An RV was thrown into a house, a car flipped, trees were knocked down, and pieces of shingles and roof decking were blown away. The tornado's ultimate rating of F2 was based on damage limited to a small area, and most damage was actually consistent with that of an F1 tornado.
The seventh tornado produced by the second tornadic storm (rated F2), which affected Northeast Oklahoma City in the Frontier City area, was also the most destructive. The tornado touched down near the Hefner Road/Bryant Avenue intersection before going on to cause major structural damage to numerous businesses. At Frontier City, the tornado damaged vehicles in the parking lot and caused the exterior of a concrete-block building to partly collapse while simultaneously taking its roof off. Inflow into the tornado caused additional damage to nearby areas, and seventeen injuries occurred at the park. East of Interstate 35, a Texaco suffered significant damage, and the tornado lifted and rolled empty semi-truck trailers in the parking lot. A nearby portable building was completely blown away. In the Nottingham and Quail Ridge Run subdivisions, extensive damage was caused to homes' windows, roofs, and garage doors. Some of these homes suffered a significant degree of roof failure despite having still-standing exterior walls. Anchoring between the roofs of these homes and their walls was missing, and it is possible that the intensity of the tornado was near the F3 range in these areas. The tornado caused $1 million worth of damage in North Oklahoma City throughout its track.
