Video shows northern Ont. storm hammer shoreline, breaking dock

The owner of a northern Ont. camp is continuing to clean up after an intense storm that prompted a tornado warning Thursday ripped through the area breaking his dock and downing trees.

Trevor Graydon of Mowat Landing Cottages on the Montreal River in New Liskeard, near the Quebec border, captured video of the rain, hail and heavy winds pummelling his shoreline the afternoon of June 13.

The fast-moving storm brought severe thundershowers to the area and prompted Environment Canada to issue weather alerts shortly before 3 p.m. warning of nickel- to ping pong ball-sized hail and up to 90 km/h wind gusts.

Heavy rain and wind pushing waves ashore on the usually peaceful waters can be seen intensifying before swirling and flying debris takes flight in the nearly two-minute video.

"Never seen an aqua blue sky like that," Graydon said in a post on social media.

Melanie Aquino Ducharme commented that the sky turned aqua blue, orange and fuschia in Haileybury during the storm.

A float plane can be seen docked at the beginning of the video footage and appears to end up along the shoreline after the dock breaks off and washes ashore.

Lesley Elliott, a research meteorologist for the Northern Tornadoes Project, told CTV News in an email that based on the video, the storm looks like a weak downburst.

"We have been reviewing witness and damage reports from the storms on the 13th and will start reviewing satellite imagery of the storm tracks as it becomes available," Elliott said.

"We have seen the report of trees down nearby and this is an area slated for satellite imagery review as well. Once we have enough information, we should be able to estimate a max. wind speed based on the damage."

Two Ontario tornadoes

No tornadoes have been confirmed yet as a result of Thursday's storm, but the Northern Tornadoes Project is reporting two 'over land' tornadoes earlier in June.

One reportedly happened June 4 in the northwest around 6:35 p.m.

"Satellite imagery review of a storm track of interest revealed tornado damage in forested areas near Landings Lake, north of Lac Seul," NTP said in its map.

"Tornado damage is assessed as EF2, with an estimated max wind speed of 190 km/h, track length of 5.67 km and max path width of 350 m.

On the afternoon of June 6, an EF0 tornado was recorded south of Ottawa.

"A tornado caused weak tree and crop damage south of Spencerville, where a section of the damage track was documented by a private citizen," NTP said.

"No injuries were reported."

A ground and drone survey was completed by NTP over the two days following the storm.

The tornado had an estimated max wind speed of 115 km/h, track length of 6.83 km and max path width of 250 m.
