Heavy snowfall is expected for most of eastern Ontario on Monday, Environment Canada says.
The weather agency says two rounds of snow are due to hit most of the province. The first is expected to hit Monday morning, and last into the afternoon. Environment Canada says this first round of snow is expected to reach about 5 cm.
The snow may stop or become light into the evening, but heavier snow is expected to start Monday night and last into Tuesday morning.
This second round may produce another 15 to 25 centimetres, the weather authority said.
Affected areas include Ottawa, Cornwall, Kingston, and Prince Edward County.
“Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow,” Environment Canada says.
