Ontario's thirteenth tornado of the season confirmed
Thursday, August 7, 2014, 3:33 PM - Ontario's thirteenth tornado of the 2014 season touched down Tuesday evening in northwestern Ontario's Grassy Narrows First Nations Community, according to Environment Canada.
The twister was ranked as an EF0 on the Enhanced Fujita Scale with top wind speeds of 130 kilometres per hour.
"Upon examination of photographic evidence, speaking with an eyewitness and corroborating with archived radar imagery, we have concluded that a weak tornado did indeed affect a section of Grassy Narrows, causing damage to the roof of one house," Environment Canada says in a statement released Thursday afternoon.

ARE TORNADOES BECOMING MORE FREQUENT?
A study published earlier this week suggests that the strength and frequency of tornadoes hitting the United States has risen sharply since the 1950s.
There are a few theories about the upswing in tornadic activity. Some experts say it could be due to our changing climate while others attribute it to the increased number of people reporting severe weather via social media.
