Following an extensive ground and aerial survey led by wind engineering experts at Western, it has been determined that the tornado outbreak of June 18, 2017 in southern Québec is officially the largest recorded in the province’s history and, consequently, one of the largest ever recorded in Canada.
Following an extensive ground and aerial survey led by wind engineering experts at Western, it has been determined that the tornado outbreak of June 18, 2017 in southern Québec is officially the largest recorded in the province’s history and, consequently, one of the largest ever recorded in Canada.
On the historic day last summer, numerous supercell thunderstorms developed in southern Québec producing large hail, high winds and damaging tornadoes.
It was previously understood that a total of four tornadoes formed that day. But new data from Western shows the number was significantly higher.
Using advanced satellite imagery covering the known damaged locations, as well as all surrounding areas, Western’s Wind Engineering experts exhaustively studied the targeted tornado region (spanning more than 400 kilometres) to isolate any previously unknown tree falls. As a result of the survey, seven new tornadoes, previously undetected, were identified raising the total of confirmed tornadoes for the Québec tornado outbreak to 11.
