May 4, 2012 — Severe thunderstorm watches and warnings were issued for large sections of Ontario Thursday night, including the city of Toronto. The result was hail, frequent lightning and flooding in parts of the province.
Thunderstorms rumbled across parts of Ontario Thursday evening, prompting Environment Canada to issue watches and warnings for dozens of communities.
In Orangeville, flooding from the storms forced dozens of residents to evacuate their homes.
By Thursday evening, around 20 people were making their way to the Tony Rose Memorial Sports Centre, which doubled as an emergency shelter. Others stayed with family and friends for the night.
On Friday morning, 14 of those people were still at the community centre, but they were discharged by 1 pm.
Officials say that damage in Orangeville could top $1 million.
More than 75 mm fell on the town by Friday morning, but Mount Forest and other communities also saw heavy rains and storm damage.
By Thursday evening, storms were firing up from Windsor to Peterborough.
Some of the most severe storms occurred around the Cambridge area, east of Kitchener-Waterloo.
Callers to The Weather Network Stormline reported storm damage and widespread power outages.
Storms also roared across the Greater Toronto Area and into the downtown core Thursday night.
"There's a slight risk for more non-severe thunderstorms on Friday as the cold front moves through," Ressler says.
"There's still some lingering moisture and instability but conditions should improve through the afternoon and evening."
