Tornado outbreak sequence of May 21–26, 2011
On May 22, a large, devastating EF5 tornado tracked through Joplin, Missouri, leaving behind catastrophic damage. It was a multiple-vortex tornado in excess of wide. Mainly the southern part of the city was affected with most structures in the area either damaged or destroyed. 162 people were killed along the path through Jasper and Newton counties in Missouri, making it the deadliest U.S. tornado since 1947, and one of the deadliest single tornadoes ever recorded. Among the most heavily damaged structures was St. John's Hospital (pictured right), which later was torn down due to the severity of the structural damage. Damages were estimated at around $2.8 billion (2011 USD).
Southern Ontario Tornado Outbreak of 2009
Damage from the tornadoes in Grey County alone is conservatively estimated at over 30 million dollars. With damage at Vaughan estimated to be well over ten million dollars, the cost of this event surpasses that of the 1996 Southern Ontario tornadoes which caused insured losses of eight million dollars, and the Hamilton, Ontario tornado of 2005 which caused twenty five million dollars in damage at Lawfield Public School. As such, the outbreak is the costliest in Ontario since 1985 directly related to Tornado Damage.
