This tornado formed northwest of the town of Wayne in McClain County near the Canadian River and moved nearly eastward along a hit-and-miss path. In southern Cleveland County, a damage path 3 miles long and 1/4 mile wide was documented. In this area, 3 barns were destroyed, trees snapped, and crops flattened by wind, rain, and hail.

The tornado continued almost due east and the worst damage was inflicted in a 7-mile-long area near Sacred Heart in southeastern Pottawatomie County and southwestern Seminole County. A tornado was observed 2 miles northwest of Konowa at 6:55 pm CST. Two persons killed and 6 injured in 3 homes which were completely leveled along this path. Many other homes and buildings were damaged. Extensive damage occurred to oil field equipment and a total of 8 rigs were destroyed with losses estimated at $40,000.

Other wind damage was reported near Wetumka, but this damage was probably unrelated to this tornado, a may have been related to another in a series of tornadoes produced by the same parent supercell thunderstorm or another supercell. It is possible that the damage caused in Wetumka was due to straight-line winds.

A tornado touched down about one mile south-southwest of Blanchard 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 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, substantial damage to a warehouse occurred at about 20:00 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 northward to about 20th Street SE.

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 526 pm CST about 2 miles south-southwest of Amber, and grew rapidly to monstrous proportions as it headed NE, paralleling I-44. It moved across Bridge Creek and rural parts of northwest Newcastle, 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 South Canadian River northeast of Newcastle and entered far south Oklahoma City SW of 149th and May Ave. around 612 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 just west and north of 12th and Santa Fe.

Still moving northeast and still producing F4 and occasional F5 damage, it crossed I-35 at the Shields Blvd. 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 I-240 between Bryant Ave. and Sunnylane Road. It crossed southeastern Oklahoma City and entered Del City 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 and Sooner Rd.

Continuing to turn slowly, it moved almost due north but maintained F4 intensity as it crossed I-40 just east of Sooner Rd. and continued north to between SE 15th and Reno Ave. The tornado then weakened rapidly to F0/F1 intensity as it crossed Reno Ave., and at 648 pm CST dissipated about 3 blocks north of Reno between Sooner Rd. and Air Depot Blvd.

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.

This long-tracked and devastating tornado developed west of U.S. Interstate Highway 35, northwest of Max Westheimer Airport. Widespread tree, power line/pole damage was reported from near I-35 to the east side of Stanley Draper Lake. Several homes also sustained damage, mainly with mostly roofs receiving significant damage, and some siding was ripped off. Several fences were also knocked down as the tornado moved northeast.

From the east side of Lake Stanley Draper, near Hiwassee Road and SE 89th Street, to just south of Harrah, the damage path became more severe and focused. The tree damage became more severe, breaking at various heights of the tree or being uprooted. Walls of homes collapsed, and debris from the homes scattered in all directions. Several 2x4's punctured roofs and ceilings over numerous structures. A few mobile homes in this area were also completely destroyed.

Where the tornado crossed U.S. Interstate Highway 40, a gas station and drive-in restaurant sustained up to EF-3 damage. The most severe damage, one of the two EF-4 tornadoes of the day, occurred in the Deerfield West Subdivision. A well-built residence here was completely destroyed, with most exterior and interior walls collapsing. The tornado finally lifted 2 miles south of Harrah. In addition to the incredible damage, one person lost their life while trying to flee the tornado.

This violent tornado touched down a few hundred yards south of the National Weather Center in Norman, Oklahoma. The damage intensity increased gradually along the path with significant damage beginning as the tornado approached Lake Thunderbird. This tornado crossed Lake Thunderbird, severely damaging two campgrounds and the marina where about 300 boats were docked.

The most severe damage occurred from the Little Axe School to the Cleveland/Pottawatomie county line. Trees were stripped of some bark and branches. Large objects were thrown considerable distances, including some concrete pillars. The metal bleachers near the school were tossed or rolled several hundred yards. Some appliances were also lofted as a dryer was found about 50 feet up in a tree. Considerable structural damage also occurred, as some foundation homes were mostly destroyed. In addition to the damage, one person lost their life as a result of the tornado.

A long track tornado began at 5:00 PM CST (6:00 PM CDT) in Cleveland County in east Norman to the north of Lake Thunderbird along 96th Avenue to the south of Tecumseh Road. The tornado moved northeast, crossing the eastern arm of Lake Thunderbird. A number of homes were significantly damaged as the tornado moved east-northeast through neighborhoods from near Indian Hills Road and 168th Avenue SE to the Pottawatomie County line.

The large tornado moved east-northeast into Pottawatomie County at 5:20 PM CST then curving northeast as it approached State Highway 102. The tornado moved through a mobile home park north of Independence Road after crossing State Highway 102. Just northeast of the mobile home park, a permanent home was destroyed with much of the debris blown well to the northeast. It continued northeast crossing U.S. Interstate Highway 40 near the intersection of U.S. Highway 177, then curved north-northeast finally dissipating near Wolverine Road and Coker Road at 5:50 PM CST. One fatality occurred in the mobile home park, and another man was killed in his vehicle.

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 to the east of Rockwell Avenue. EF4 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 44. The tornado then turned more east and then east-northeast after crossing I-44. Violent E-F4 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 and Moore 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 35.

Although the tornado was narrower after crossing 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, 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 Blvd. 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.
