Environment Canada confirmed a tornado touched down in northwestern Ontario after funnel clouds were reported in several communities late Tuesday afternoon.
A tornado was spotted near Dryden Airport at 4:30 p.m. and northwest of the Sioux Lookout Airport at 5:40 p.m.
The agency said the tornado track was about 80 kilometres long, but the agency will determine the rating of the storm on Wednesday.
There were no reports of damage.
CityNews weather specialist Sangita Patel said the same cold front could bring wet weather to the GTA on Thursday.
“That same cold front is supposed to bring Toronto showers for tomorrow,” she said.
“It’s losing its energy right now, but there is still a chance of rain with a risk of thunderstorms for the GTA.”
Tornado warnings issued by Environment Canada for Kenora, Dryden, Vermilion Bay, Sioux Lookout and Fort Frances were lifted just before 7 p.m. Tuesday. But a severe thunderstorm watch remained in effect over much of the northwest for that evening.
