...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.
