Environment Canada has issued a warning for Toronto, saying heavy rain is expected to hit the city.
The weather agency issued the warning at 3:30 p.m. on Wednesday, saying rainfall amounts between 30 and 50 millimetres are possible.
“Locally higher amounts of 60 mm are possible for areas which receive multiple thunderstorms,” the warning read.
Environment Canada said the rain is expected to continue into Wednesday evening.
“Based on RADAR and unofficial reports, some locales may have received up to 40 mm,” the agency said.
Environment Canada said heavy downpours can cause flash floods and water to pool on roads.
The agency warneed that localized flooding in low-lying areas is possible.
