A special weather statement is in effect for Toronto and the GTA warning of heavy rainfall for most of the day.
Environment Canada says anywhere between 30 to 50 millimetres of rain could fall across the region, including Mississauga, Brampton, Vaughan and Durham regions due to heavy rain and thunderstorms on Saturday.
“Drivers should watch out for ponding and pooling on the roads and flooding on certain ramps that are prone to flooding,” said CityNews 680 meteorologist Carl Lam. “If you see a road that is flooded, do not drive through it and turn around.”
The Toronto and Region Conservation Authority echoed similar concerns when it comes to rivers and streams in the area.
“All TRCA rivers within the GTA may experience higher than normal flows and water levels for the next few days,” the regional authority said in a statement. “The combination of slippery, unstable banks, and changing water levels could create hazardous conditions in and near rivers or other water bodies.”
A rainfall warning is in effect for Hamilton and the Niagara Region, calling for upwards of 50 millimetres of rain.
“The storms in these regions have been consistent and heavy, at times,” said Lam. “Flooding for lakes, creeks, and streams is also a concern with this much rainfall in such a short amount of time.”
