Morning commuters are advised to take it slow while on the road as dense fog may cause poor visibility in some areas.
Environment Canada issued a fog advisory Monday morning for St. Thomas, Elgin County and Norfolk County. A fog advisory briefly issued for London-Middlesex and Oxford County has ended.
The national weather agency said travel is expected to be hazardous in some areas because of reduced visibility. In which case, drivers are reminded to reduce their speed, turn on the vehicle's lights, and maintain a safe following distance.
