A tornado watch that was issued for parts of eastern Ontario including Ottawa has ended.
The watch was issued by Environment Canada at around 11:30 a.m., on Thursday.
Officials said conditions were “favourable for the development of severe thunderstorms” that could produce tornadoes.
The weather agency also warned of strong winds, large hail and heavy rain.
By mid-afternoon Thursday, a severe thunderstorm warning had also been issued for several areas in eastern Ontario.
Environment Canada said tornadoes were possible, along with wind gusts of 90 to 110 km/h and nickel to ping pong ball-sized hail.
Global News’ Chief Meteorologist Anthony Farnell said it was an “active day of weather” on Thursday as “hot and humid conditions collided with a cold front and produced several thunderstorms.”
“Reports of trees down in some locations along with large hail as big as ping pong balls in places like Scarborough,” he said. “Some of these storms were rotating and prompted tornado warnings east of the GTA. Survey crews will be out tomorrow to investigate if any tornadoes occurred.”
According to Farnell, almost 35,000 Hydro One customers are in the dark after Thursday’s severe storms – most across eastern Ontario.
Farnell said the temperature will “quickly cool this evening as the humidity breaks.”
“It will almost be cool by Saturday with highs remaining in the upper teens under partly sunny skies,” he said.
