...Ongoing investigations add three more tornadoes to Ontario's list
For 2013 ...

At around 10 P.M. on July 18, a line of strong thunderstorms moved 
through the region to the north of Lake Huron. One of these storms 
produced tree damage and some minor structural damage in an area just 
north of massey, which is approximately 85 kilometres southwest of 
Greater Sudbury. An Environment Canada storm investigator viewed the 
damage earlier this month and found a damage path roughly 250 metres 
wide and 7 kilometres long. The damage to the trees and structures 
was consistent with an enhanced Fujita scale one (ef-1) tornado, with 
peak winds between 135 and 175 kilometres per hour.

On August 7, a series of strong thunderstorms generated three 
confirmed tornadoes in southcentral and Eastern Ontario. Another 
event has come to light from this day. At approximately 5:30 P.M., a 
swath of trees were snapped or uprooted about 5 kilometres to the 
northwest of Haliburton. Environment Canada was recently provided 
with aerial imagery of this damage. Based upon the long and 
relatively narrow track of tree damage, this event has been 
classified as an ef-1 tornado.

In addition, the original storm summary for the outbreak of August 7 
mentioned a waterspout being confirmed over head lake in the northern 
part of the Kawartha Lakes region. Waterspouts are, by definition, 
tornadoes that occur over water. While Great Lakes waterspouts are 
not included in the provincial tornado count unless they come ashore, 
waterspouts forming in association with thunderstorms over smaller 
bodies of water have been included in the tornado database in the 
past. Therefore, this event has now been added to the tornado count 
for this year in Ontario. It has been rated as an enhanced Fujita 
scale zero tornado (ef-0), with peak winds between 90 and 130 
kilometres per hour, because no appreciable damage was caused.

With the addition of these three tornadoes, the total now stands at 
17 in Ontario for the season so far. Ontario normally verifies 12 
tornadoes each year in a season that usually runs from late April 
until early October. While the number of events so far this year is 
greater than the long-term average, fortunately most of these events 
have been weak and short-lived. The popularity of smartphones and 
social media has also played an important role this season in the 
identification of a number of these tornadoes.
