Environment Canada has issued a snowfall warning for Windsor, Essex County and Chatham-Kent for between 15 and 20 centimetres of snow by Friday evening.
The snow should start falling after midnight and continue throughout the day Friday across Essex County.
“Driving conditions will quickly deteriorate after the snow arrives overnight,” said Environment Canada in its warning.
“Both the morning and afternoon commutes will be affected. Motorists should adjust travel plans accordingly.”
The weather agency said people should be ready for bad driving conditions caused by quickly accumulating snow and reduced visibility.
“Visibility may be suddenly reduced at times in heavy snow,” Environment Canada said.
“Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. There may be a significant impact on rush hour traffic in urban areas.”
