Le 22 juin 2007, une tornade de force 5 sur l'échelle de Fujita (F5) s'est abattue sur le village d'Elie, situé à quelques dizaines de kilomètres à l'ouest de Winnipeg. Many other tornadoes have never been formally rated by an official government source but have nonetheless been described as F5/EF5 or equivalent, often by independent studies. F5 winds were suspected to be in the 261 to 318 mph range at the time of rating. These conditions were favourable for The tornado approaching the town of Elie, Manitoba (Canada) around 6:50 PM local timeCanadian inflation numbers based on Statistics Canada tables 18-10-0005-01 (formerly CANSIM 326-0021) At the same time as the Elie tornado, another tornado was touching down close to nearby Very warm air was situated over Southern Manitoba that day as temperatures climbed into the high 20s °C (low 80s °F). Cette tornade est considérée comme une F4 ou F5.

Unless otherwise noted, the source of the F5 rating is the U.S. The tornadoes on this list have been formally rated F5 by an official government source. It is still Canada’s strongest tornado on record. Ultimately, a new scale was devised that took into account 28 different damage indicators; this became known as the In the United States, between 1950 and January 31, 2007, a total of 50 tornadoes were officially rated F5, and since February 1, 2007, a total of nine tornadoes have been officially rated EF5.Several other tornadoes have also been documented as possibly attaining this status, though they are not officially rated as such. This makes it one of the strongest twisters on record since 1999 and one of only nine to reach F5/EF5 intensity between 1999 an… Strong wind shear was present, reflected in high helicity values. Unless otherwise noted, the source of the F5 rating is the U.S. National Weather Service (NWS), as shown in the archives of the Storm Prediction Center (SPC) and National Climatic Data Center (NCDC). An additional four tornadoes which occurred prior to 1950, all in Europe, have been officially rated F5 or equivalent by the Because the distinctions between F4/EF4 and F5/EF5 tornadoes are often ambiguous, the official ratings of numerous other tornadoes formally rated below F5/EF5 or equivalent have been disputed, with certain government sources or independent studies contradicting the official record. The work of tornado expert The tornadoes on this list have been formally rated F5 by an official government source. A few, such as the Possible F5/EF5 tornadoes officially rated F4/EF4 or lowerPossible F5/EF5 tornadoes officially rated F4/EF4 or lowerThe winds estimated by the Fujita Scale are estimated values and have not been verified scientifically. While several houses were leveled, no one was injured or killed by the tornado. Prior to 1950, assessments of F5 tornadoes are based primarily on the work of Thomas P. Grazulis. A home in the town was swept clean off of its foundation, justifying the F5 classification.

Most of these tornadoes occurred prior to 1950, before tornadoes were rated according to standardized damage assessments, and their unofficial classifications as F5/EF5 or equivalent have been made in retrospect, largely on the basis of photographic analysis and eyewitness accounts. This page lists tornadoes and tornado outbreaks which have touched down in Canada prior to the 21st century.On average, there are around 80 confirmed and unconfirmed tornadoes that touch down in Canada each year, with most occurring in the southern Canadian Prairies, Southern Ontario and southern Quebec.Canada ranks as the country with the second most tornadoes per year, after the US.

In addition to the accepted ones, Grazulis rated a further 25 during the same period which were not accepted.As of February 1, 2007, tornadoes in the United States are rated using the Worldwide, a total of 62 tornadoes have been officially rated F5/EF5 since 1950: 59 in the United States and one each in France, Russia, and Canada. Of the 59 tornadoes in the United States, 50 are officially rated F5 on the original Fujita scale (with dates of occurrence between May 11, 1953, and May 3, 1999), and nine are officially rated EF5 on the Enhanced Fujita scale (with dates of occurrence between May 4, 2007, and May 20, 2013). Following two particularly devastating tornadoes in 1997 and 1999, engineers questioned the reliability of the Fujita scale. The Elie, Manitoba tornado was an extremely powerful F5 tornado that struck the town of Elie, in the Canadian province of Manitoba (40 kilometres (25 miles) west of Winnipeg), on the evening of Friday, June 22, 2007. Cependant, la première tornade F5 officiellement documentée au Canada a frappé Elie, au Manitoba, le 22 juin 2007.

Une tornade F5 est d’une force incroyable et la vitesse des vents varie de 418 à 509 km/h. Prior to 1950, assessments of F5 tornadoes are based primarily on the work of Thomas P. Grazulis. The NCDC has accepted 38 of his F5 classifications of tornadoes occurring between 1880 and 1950. This page lists all the confirmed and unconfirmed tornadoes which have touched down in … The humidity was also uncomfortably high, with dewpoints ranging from 18–22 °C (64–72 °F).
