Default 2017 Tornado Statistics

(1) Apr.27, 2017, 10:50 - EF1 - Thamesford (near London): ON APRIL 11TH, A THUNDERSTORM THAT DEVELOPED OVER SOUTHWESTERN ONTARIO INTENSIFIED NORTHEAST OF LONDON, ONTARIO CAUSING DAMAGE TO A BARN ROOF AND DOWNED TREES AND HYDRO POLES. AFTER AN ANALYSIS OF WITNESS REPORTS AND A DAMAGE SURVEY CONDUCTED BY WESTERN UNIVERSITY, A POST-STORM INVESTIGATION BY ENVIRONMENT CANADA HAS CONCLUDED THAT THE DAMAGE WAS THE RESULT OF BOTH A TORNADO WITH PEAK WINDS UP TO 150 KM/H, RATED EF-1 ON THE ENHANCED FUJITA SCALE, IN ADDITION TO DOWNBURST WINDS. THE TORNADO PATH WAS APPROXIMATELY 11 KM LONG AND 200 M WIDE. More info here: https://www.theweathernetwork.com/ne...of-2017/81728/

(2) Jul.6, 2017 - 15:40 - EF2 -Ottertrack Lake (Quetico Provincial Park) - On July 6th, a particularly dangerous thunderstorm that developed over Quetico Provincial Park in Northwestern Ontario intensified as it traveled southeastward. A tornado warning was issued at approximately 3:40 PM EDT based on radar imagery. The next day, aerial reconnaissance by the Provincial Ministry of Natural Resources and Forestry showed a damage path about 100 metres wide and up to 2 km in length across Ottertrack Lake in the extreme southeastern part of the park which is located near the United States border. Most trees were flattened along this damage path. As a result of the length of the track and the dispersion in tree damage orientation, Environment Canada has concluded that the damage was the result of a tornado with peak winds up to 190 km/h. This is rated as an EF2 on the Fujita scale. Please note that this summary may contain preliminary or unofficialinformation and does not constitute a complete or final report. End/OSPC

(3) Jul.12, 2017 - 16:20 - Waterspout - Lake Simcoe: Southwestern and Central Ontario experienced strong storms during the afternoon and evening hours on Wednesday. At approximately 4:20 PM Wednesday afternoon, a tornado occurred over Lake Simcoe near Georgina Island. Tornadoes that occur over bodies of water are known as waterspouts. This particular waterspout had the capability to move inland and do damage but to this point in time, no damage has been reported in that area.

(4) Jul.12, 2017 - 19:00 - EF0 - Lucan: At approximately 7:00 PM on Wednesday, a tornado occurred just to the north of Lucan in Middlesex County. Environment Canada received a number of reports through social media of this event and the damage that ensued. Engineers from Western University in London conducted a damage survey and concluded that this was an Enhanced Fujita Scale 0 (EF0) tornado with peak winds of 130 km/h. The length of the damage path was 5 km and the maximum width was 170 metres. The tornado uprooted some trees and overturned some trailers on a farm property.

(5) Jul.12, 2017 - (possible tornado) - 20:20 Drumbo: At approximately 8:20 PM on Wednesday, the same storm cell that spawned the Lucan tornado generated a possible tornado in the Drumbo area. Environment Canada has received images of a funnel cloud in this area. At this time, there is no evidence that a tornado occurred and caused damage. The investigation into this event continues.

THE TORNADO TRACKED ABOUT ONE KILOMETRE NORTHEASTWARD OVER LAND AND THEN FOR ANOTHER ONE TO ONE AND A HALF KILOMETRES OVER FAIRY LAKE AS A TORNADIC WATERSPOUT. DAMAGE WAS REPORTED TO A NUMBER OF HOMES AND NUMEROUS TREES WERE TOPPLED. THE WIDTH OF ITS PATH IS ESTIMATED TO HAVE RANGED FROM 100 TO 150 METRES WITH WIND STRENGTH OF 130 TO 150 KM/H.

From the storm damage survey it appears the tornado produced winds up to 190 km/h and had a track length of nine kilometers. Currently it is believed this tornado started near Pell Lake and moved northeastward to Rebecca Lake then continued to Dotty Lake. The width of the damage path is estimated to range from 100 to 200 metres. The tornado caused extensive tree damage as well as structural damage to cottages.

(8) Aug.4, 2017 - EF1 - Utterson: A third tornado has been confirmed to have occurred this past Friday August 4th, 2017 in the Huntsville area.

The tornado has been classified as an EF1 with a maximum wind speed estimated at 160 km/h and a path length of 4.2 kilometres and a maximum width of 250 metres.

(9) Aug.11, 2017 -17:40 - EF0 - Leamington: Late Friday afternoon, a thunderstorm moved from lower Michigan across Essex County and reached Leamington near 5.40 PM.

(9) Aug.11, 2017 -19:30 - EF2 - Hawksville: Environment Canada damage assessment team has confirmed an EF-2 tornado near Hawksville at about 7:30 PM.
