Environment Canada says it has concluded that a tornado touched down in the Grassy Narrows area this week.
Meteorologists issued a severe thunderstorm watch on Tuesday evening, and the weather service subsequently received a report that a tornado had been spotted around 7:30 p.m.
The report came from a resident of the Grassy Narrows First Nation whose home suffered roof damage.
Meteorologist Peter Kimbell said the eyewitness account helped Environment Canada confirm the tornado.
“I spoke to the gentleman who lives at the house and he saw a funnel cloud, actually a water spout on the lake coming toward the house,” he said.
“There was a bit of shingle damage to the house but, based on his testimony, we concluded that there had been a weak tornado that had moved through the area.”
Kimbell said the account was also consistent with what Environment Canada saw on radar.
