1999 Salt Lake City tornado

Last updated

1+1⁄2 inches (3.8 cm) diameter hail was reported near the town of Herriman. Afterwards, the storm started rotating, and at around 1:00 pm, many people reported seeing the storm rotate (forming a mesocyclone) as it moved into downtown Salt Lake City. A non-descending funnel cloud developed and traveled from western downtown toward the northeast before terminating near Memory Grove Park upon reaching the base of the Wasatch Mountains. [4] The tornado remained on the ground for about 14 minutes over the span of about 4.25 miles (6.84 km). [1] [7]

The tornado damaged or destroyed approximately 800–1,000 trees [7] [8] [9] and destroyed temporary tents set up for the Outdoor Retailers Association convention, claiming the life of one booth set-up supervisor, Allen Crandy, 38, of Las Vegas. In The Avenues, over 154 homes were severely damaged, about 120 of which had roofs blown off. Over 100 people were reported injured and a dozen critically. In total, 300 buildings were damaged or destroyed. [8]

At the Delta Center, home of the Utah Jazz of the National Basketball Association, the tornado shattered windows and tore off part of the roof. [10] Almost all of the windows from the nearby Wyndham Hotel (now the Radisson Hotel), across the street from the temporary tents, were broken out, raining down shards of glass on people attempting to escape from the collapsed tents. A crane toppled at the LDS Conference Center that was under construction. [11] Damage to historic buildings in the lower Capitol Hill area of Salt Lake was reported. Nearly all of the trees in Memory Grove, a World War I memorial park at the mouth of City Creek Canyon near downtown, were reportedly torn out, as well as hundreds of old trees on the Capitol grounds.[ citation needed ]

This was the first major tornado to occur in a large urban area's downtown district and strike buildings of nearly 500 ft (150 m) tall, according to Bill Alder of the National Weather Service. It happened in an area of the U.S. where tornadoes of this strength are relatively rare. The tornado caused approximately $170 million in damage. [9]

The Southern Ontario Tornado Outbreak of 2009 was a series of severe thunderstorms that spawned numerous tornadoes in Southwestern Ontario, Central Ontario and the Greater Toronto Area (GTA) on August 20, 2009, and was the largest single-day tornado outbreak in Ontario history and the largest in Canadian history. During the afternoon and evening, 19 tornadoes touched down with four of them producing F2 damage. One F2 struck the town of Durham where significant damage occurred and one person was killed; two F2s struck the city of Vaughan, just north of Toronto, damaging hundreds of homes; another F2 devastated apple orchards and resort areas near Thornbury. The number of tornadoes associated with this event surpasses that of August 2, 2006, which saw 18 documented tornadoes. In addition, it was one of the most destructive and costly tornado events ever in the province, and included one fatality, one of only a handful of deadly tornadoes in Ontario's recent memory. At one point, over 10 million people in Southern Ontario, one-third of Canada's population, were placed under tornado watches and/or warnings as the storms rolled through.

A localized, but destructive and deadly tornado outbreak impacted Tennessee, Alabama, and Georgia on Leap Day in 1952. Thanks in part to unseasonably strong jet stream winds and a strong cold front, eight tornadoes left trails of damage and casualties. The tornado to cause the most casualties was an F1 tornado in Belfast, Tennessee, which killed three people and injured 166. A violent F4 tornado moved through Fayetteville, Tennessee, destroying most of the town and killing two and injuring 150 others. On the north side of Fort Payne, Alabama, an F3 tornado caused major damage and injured 12 people. In all, the outbreak killed five, injured 336, and caused $3.1 million (1952 USD) in damage. Four more fatalities and 14 more injuries occurred from other non-tornadic events as well.
