Watch out in your morning commute.
Setting Canada has issued a fog advisory for southwestern Ontario.
It stretches from Windsor-Essex and Chatham-Kent and extends into London-Middlesex, Lambton, Elgin, Oxford, Brant, Huron- Perth, Gray-Bruce, Norfolk and Haldimand.
Widespread fog has settled over the area with close to zero visibility in some areas.
Roads and sidewalks could also be slippery as temperatures sit under or near the freezing mark, and the fog could deposit ice on untreated surfaces.
The fog is anticipated to elevate all through the morning.
