Environment Canada has updated its special weather bulletin to a severe weather bulletin for much of southern Ontario.
A snowfall warning has ended for Middlesex-London, Oxford County, Elgin, Chatham-Kent, Sarnia-Lambton, and Windsor-Essex but there is still a snowfall warning in effect for Huron-Perth and Grey-Bruce. About 15-25 centimetres of snow was expected to fall, starting overnight Sunday.
Roughly 5-10 cm of snow is expected to fall before Monday afternoon, with a chance of some snow squall activity near Lake Huron.
Environment Canada said snowfall could ease up by Monday afternoon, but another round of even heavier snow is expected to move in Monday evening and persist until Tuesday morning. The second round is expected to bring another 10-20 cm.
Visibility may be reduced at times. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
Environment Canada said to prepare for quickly changing and deteriorating travel conditions.
