Residents in Chatham-Kent and Windsor-Essex better keep their snow shovels handy.
Environment Canada issued a special weather statement Tuesday evening advising of a low pressure system that is expected to bring another round of snowfall to the regions late Wednesday night.
The weather agency says around 10 cm of snowfall is expected, but Windsor, Leamington and Essex County could see up to 15 cm.
Drivers are urged to use caution as untreated roads may become snow covered and slippery.
