The tornado touched down briefly in west Mesa before dissipating. The storm was accompanied by heavy hail.

September 14, 1971

At about 7:15 p.m., three funnel clouds aloft were observed approaching and converging on the Treadway Ranch located near 83rd Avenue and Thomas Road. These funnels were about 50 feet wide at the bases and tapered larger to the cloud base. They touched down briefly over the corral area where there were 15 people and many prize horses. They ripped off the roof of one of the barns and did other damage to structures and equipment in the immediate area. Miraculously no people or animals were inured by the debris. Eyewitnesses stated that the first two funnels struck almost simultaneously followed by a dead calm before the third struck.

June 13, 1972

At 7:33 p.m., a small tornado touched ground briefly near 40th Avenue and Southern avenue in southwest Phoenix. Two house-trailers were demolished, a utility pole blown down, and several trees uprooted. The length of path was about 1/4 mile. Estimated damage was about $40,000.

June 21, 1972

At 6:30 p.m., extremely heavy wind damage to property along a 2-mile front was inflicted in the northern part of Paradise Valley. Inspection of the area by National Weather Service personnel after the storm, indicated that several tornado funnels, traveling together, were probably responsible for the destruction. One witness reported seeing two funnels close to one another at the height of the storm. There was also evidence that these funnel clouds touched ground in the vicinity of 36th Street and Camelback Road in Phoenix, then traveled northeastward into Paradise Valley. Also the pattern of damage in the area indicated that more than one vortex of high velocity winds passed through the area. Several hundred homes were either completely demolished or extensively damaged. Many homes that escaped complete destruction on the night of the 21st, were further damaged on the morning of the 22nd, when additional thunderstorms in the area caused heavy rains. The Arizona Statistical Division of Emergency Services made an estimate of the total property damage for the two-day period (June 21-22, 1972) of $10,800,000. Because of the relatively short-time internal between storms on the two days, it was impossible to estimate the tornado damage alone on the 21st.

August 12, 1972

At 8:00 p.m., a small tornado touched ground briefly in south Phoenix in an unpopulated area. No damage.

September 10, 1972

Observers reported frequent cloud-to-cloud lightning near the storm and that some strokes were copper-green in color. One injury occurred when a seventeen month-old girl was cut by flying glass. Property damage was estimated at $1,000,000 by Maricopa County Emergency Services.

October 18, 1972

The tornado lasted about 12 minutes, and no property damage occurred.

May 4, 1976
