At 4:03 p.m. on Wednesday, Environment Canada meteorologists say they were tracking a severe thunderstorm that is possibly producing a tornado. Damaging winds, large hail and locally intense rainfall are also possible.

Monica Vaswani, warning preparedness meteorologist for Environment and Climate Change Canada, said a line of thunderstorms moving west to east travelled through the region from Michigan. Along that line as it moved through the Windsor-Essex region, that indicated some rotation on radar, which prompted the tornado warnings. The rotation is no longer present on radar.

As the line of thunderstorms rolled through the region, with it came heavy rain and strong winds taking down a number of hydro poles and trees in its wake.

Vaswani said Environment and Climate Change Canada does not currently know of any tornadoes that have touched down in the region, but there have been reports of very high wind gusts.

“We have seen actual reports, so Harrow did report a wind gust as high as, I believe, 91 km/h. What warrants a severe thunderstorm for winds would be 90 km/h so that is definitely in the severe category,” she said.

 Vaswani said parts of southwestern Ontario are still under a severe thunderstorm warning, including Chatham-Kent and Rodney. The warning for Windsor-Essex has ended, but the region is still under a watch.

“There is still some thunderstorm and shower activity behind this line, the main line however has moved ahead. I would caution against thinking that all’s clear. We do still have severe thunderstorm watches in the Windsor area, so I would wait until those watches have been dropped to take that as a go that everything’s sort of calmed down in Windsor,” she said.

Vaswani reminds residents to continue to making sure that you’re keeping an eye on the updated severe thunderstorm watches, warnings and of course possible tornado warnings. 

Dr. David Sills, executive director of the Northern Tornado Project, said in an email they are aware there is storm damage in Kingsville Blenheim and Harrow, but whether that was a downburst or a tornado that caused it needs to be looked into.

The Northern Tornadoes Project will be sending a team from London to the area Thursday morning investigate.
