Kitchener, Waterloo and Cambridge have declared snow events starting at midnight and there's an on-street parking ban starting at 11:59 p.m. Wednesday.

The ban is in place for 24 hours unless it is extended or cancelled by each individual city.

Environment Canada issued a special weather statement for Waterloo region, saying between 10 to 15 cm of snow is expected by Thursday morning. Snow will be heavy in the afternoon and throughout the night.

"On Thursday, intense snow squalls with heavy snow and blowing snow are expected to develop east of Lake Huron. These snow squalls will likely continue into Saturday," the statement said.

"Motorists should be prepared for poor winter driving conditions due to low visibility in heavy snow and blowing snow over the next few days."

Kitchener says during a snow event, the city's tag-and-tow bylaw takes effect.

"Residents are prohibited from parking their cars on city streets at any time when a snow event has been declared," the city said in a release, noting bylaw enforcement can issue a ticket or have a vehicle towed at the owner's expense.

On its website, Waterloo reminded drivers that "removing cars from streets helps us with safe and quick snow removal."

Cambridge also reminded residents who are shovelling "not to push snow from their driveway onto the road."

Overnight parking exemptions are not recognized during snow events in the cities.
