Environment Canada has issued a Snowfall Warning for Perth and Huron Counties.
Between 15 and 20 cm are expected to fall.
The agency says the snow should continue to fall until at least mid-afternoon in many areas.
The heavy snowfall is mixing with gusty winds and causing reduced visibility and snow to build up on area roads.
If you have to drive somewhere today make sure you leave early to give yourself lots of time to get there.
If possible you should consider postponing your travel plans until conditions improve.
