  11/19/1973 1930 24 500 F3 5 46 McClain/ Cleveland/ Oklahoma Blanchard - Moore - Del City - SE Oklahoma City

A tornado touched down about one mile south-southwest of Blanchard, OK in McClain County at 7:30 pm CST and moved north-northeastward at 40 mph. The tornado moved through the western portions of Blanchard with top damage wind speeds of 150-175 mph. Thirty-one homes, 2 businesses, and 2 churches were destroyed, and 44 homes along with 2 businesses received major damage. Two occupants of a mobile home were killed and 18 others were injured. Total damages to insured property were $1.8 million. In addition, minor damage in Alex (17 miles south-southwest of Blanchard) may have been associated with this tornado.

Heavy rain accompanied the tornado and apparently obscured any noise made by the storm. The tornado caused spotty damage northeast of Blanchard, mostly light, and then it moved through Moore, OK where it struck a mobile home park in southern Moore, and then many homes and businesses in the northern sections of the city. Two children were killed in the mobile home park where 37 mobile homes were destroyed and 30 others were damaged. On some mobile home trailers, only the frame of the floor and wheels remained. Of the 28 injuries in Moore, most occurred at the mobile home park. Total damages in Moore totaled $2.5 million.

As the tornado moved north-northeast into southern Oklahoma City, OK, substantial damage to a warehouse occurred at about 8:00 pm CST along 89th Street. A watchman at the warehouse was killed when a concrete block wall collapsed on him. As the tornado continued on, minor roof damage occurred in southeastern Oklahoma City and Del City, OK northward to about 20th Street SE.

  05/03/1999 1726-1848 38 1760 F5 36 583 Grady/ McClain/ Cleveland/ Oklahoma 2 SSW Amber - far N Newcastle - SW Oklahoma City - N Moore-S Del City-W Midwest City

This violent, long-lived tornado was the most infamous of nearly 60 tornadoes that struck central Oklahoma during an unprecedented outbreak on this Monday afternoon and evening of May 3, 1999. The tornado was the 9th of 14 tornadoes produced by a supercell thunderstorm during the tornado outbreak. It formed around 5:26 pm CST about 2 miles south-southwest of Amber, OK, and grew rapidly to monstrous proportions as it headed to the northeast, paralleling U.S. Interstate Highway I-44. It moved across Bridge Creek, OK and rural parts of northwest Newcastle, OK, causing continuous F4 and sporadic F5 damage. The tornado was estimated to be a mile in diameter in this area.

It weakened to F2/F3 intensity and narrowed to less than 1/4 mile in width as it crossed I-44 and the Canadian River northeast of Newcastle and entered far south Oklahoma City, OK southwest of 149th and May Avenue around 6:12 pm CST. But it regained F4/F5 intensity and widened again to 1/2 to occasionally 3/4 mile as it moved northeast across south Oklahoma City, entering Moore, OK just west and north of 12th and Santa Fe.

Still moving northeast and still producing F4 and occasional F5 damage, it crossed U.S. Interstate Highway I-35 at the Shields Boulevard junction and moved into northeast Moore, at which point it weakened slightly to F3/sporadic F4 intensity and began a gradual turn to the left. This turn took the tornado more to the north-northeast as it crossed U.S. Interstate Highway I-240 between Bryant Avenue and Sunnylane Road. It crossed southeastern Oklahoma City and entered Del City, OK as an F4 tornado, width 1/3 to 1/2 mile, along SE 44th between Sunnylane and Sooner Roads, and continued north-northeast to the northwestern part of Tinker Air Force Base, near SE 29th Street and Sooner Road.

Continuing to turn slowly, it moved almost due north but maintained F4 intensity as it crossed U.S. Interstate Highway I-40 just east of Sooner Road and continued north to between SE 15th Street and Reno Avenue. The tornado then weakened rapidly to F0/F1 intensity as it crossed Reno Avenue, and at 6:48 pm CST dissipated about 3 blocks north of Reno between Sooner Road and Air Depot Boulevard.

Totals from this tornado include 36 direct fatalities (12 in Bridge Creek, 1 in Newcastle, 9 in southern/southeastern Oklahoma City, 5 in Moore, 6 in Del City, and 3 in Midwest City), 5 indirect fatalities during or shortly after the tornado, 583 direct injuries, numerous indirect injuries (too many to count), 1800 homes destroyed, and 2500 homes damaged. The tornado was also the 100th tornado to strike the Oklahoma City area since 1890. Total damage was estimated at $1 billion.

  05/24/2011 1606-1701 33 880 EF4 1 48 Grady/ McClain/ Cleveland 2 S Chickasha - SW Oklahoma City (near SW 149th and Portland)

This tornado formed on the south side of Chickasha, OK in Grady County, quickly doing EF-2 damage. Mobile homes were damaged and destroyed, trees were uprooted or destroyed, outbuildings were destroyed, and many buildings lost significant portions of their roofs. One fatality occurred as a mobile home was destroyed in the south portion of Chickasha. As the tornado moved northeast of Chickasha, it gained significant strength, with several areas receiving EF-4 damage. Well-built homes were destroyed. Trees were debarked with only stumps remaining. Cars were thrown hundreds of feet. Almost continuous EF-3/occasional EF-4 damage occurred northeast until it crossed into McClain County, 1.5 miles south of OK State Highway 9. The tornado was probably at its strongest as it neared/crossed the Grady/McClain County line. Wind speeds there were estimated near 200 mph in this area.

Significant damage continued as the violent tornado moved over the McClain County border. This may have been the strongest portion of this tornado, with wind speeds near 200 mph. Well-built homes were destroyed, with some cleaned off of their foundation. A concrete dome home was severely damage, mainly by the flying debris. Trees were debarked or destroyed. Very little was left standing for the first few miles into McClain County. Fairly consistent EF-3, with brief periods of EF-4 damage occurred as the tornado approached and then crossed OK State Highway 9, near the OK State Highway 76 junction. The tornado began to weaken as it moved toward the Cleveland County border, with mainly trees and power poles/lines snapped.

The tornado continued into Cleveland County and where some minor tree/power pole/power line damage occurred. A few barns and outbuilding also sustained minor damage east of U.S. Interstate Highway I-44. The tornado dissipated just north of the Canadian River. The tornado traveled along a path length of 32 miles through three counties in just under an hour, Peak wind speeds were estimated just under 200 mph.

  05/20/2013 1356-1435 14 1900 EF5 24 212 McClain/ Cleveland Newcastle (3 NW US-277/SH-130) - 3 WNW Stanley Draper Lake Dam

The violent Newcastle-Moore tornado was first observed at 1:56 pm CST (2:56 pm CDT) developing about one-half mile south of Oklahoma State Highway 37 in northwest Newcastle, OK to the east of Rockwell Avenue. EF-4 damage was observed soon after the tornado crossed State Highway 37. The tornado continued to expand in size as it approached the Canadian River and moved into Cleveland County.

The tornado then moved into Cleveland County at 2:04 pm CST from McClain County as it moved northeast across the Canadian River near U.S. Interstate Highway I-44. The tornado then turned more east and then east-northeast after crossing I-44. Violent EF-4 damage was again observed as it began to move into progressively higher density residential areas approaching May Avenue.

The center of the large tornado path passed near SW 149th Street and Western Avenue. After crossing Western Avenue, numerous buildings were destroyed and horses killed at Orr Family Farm. Two storage tanks estimated to weigh approximately 10 tons were lifted from Orr Family Farm and landed about one-half mile east.

Moving east, the tornado destroyed much of Briarwood Elementary School, where the NWS storm survey team rated damage as EF-5. Despite the destruction of this elementary school during school hours, no fatalities occurred at the school. As the tornado continued to move east and east-northeast, it moved through much more densely populated suburban neighborhoods of southwest Oklahoma City, OK and Moore, OK where violent destruction was widespread.

The width of EF-4 and greater damage was up to 250 yards wide as the tornado moved through neighborhoods east of Western Avenue. The first two fatalities occurred in a house in the neighborhood just east of Briarwood Elementary, with another fatality in a house as the tornado approached Santa Fe Avenue.

After crossing Santa Fe Avenue, the tornado moved through more suburban neighborhoods and toward Plaza Towers Elementary School. Damage to the school was extensive and seven children were killed when a wall collapsed at the school. Nine other people were killed in eight different neighborhood homes within one-quarter mile of Plaza Towers Elementary, most occurring just south of the school.

The tornado turned northeast as it approached Telephone Road, made a loop near the intersection of Telephone Road and 4th Street, then moved southeast crossing the interstate. Three people were killed when a convenience store along Telephone Road was destroyed. Crossing Telephone Road, the tornado inflicted significant damage to the Moore Medical Center, a post office and numerous businesses along Telephone Road and U.S. Interstate Highway I-35.

Although the tornado was narrower after crossing U.S. Interstate Highway I-35, it continued to produce EF-4 damage in neighborhoods east of the interstate as it curved east and then again east-northeast. One fatality occurred at a business just east of the interstate highway, and one final fatality occurred in a home between Eastern Avenue and Bryant Avenue. Consistent EF-4 damage continued until the tornado passed SE 4th Street just east of Bryant Avenue.

Moving east from Bryant Avenue, the tornado continued to produce EF-2 damage with isolated EF-4 damage noted. The density of housing also decreased east of Bryant as the tornado moved east and east-northeast before dissipating at 2:35 PM CST east of Air Depot Boulevard between SE 119th Street and SE 134th Street in southeast Oklahoma City. Overall, over 300 homes experienced EF-4/EF-5 damage along the tornado path.
