A fog advisory is still in effect for Windsor-Essex and Chatham-Kent.
According to Environment Canada, the dense fog that has hung in the air throughout most of the day in Windsor-Essex is expected to persist through Thursday evening.
The weather authority recommends if travelling, that drivers be prepared for areas of near-zero visibility. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.
Fog advisories are issued when near zero visibilities in fog are expected or occurring.
School buses were cancelled for the morning in Windsor, Essex and Chatham-Kent. But the buses were in operation for Thursday afternoon.
The fog across southwestern Ontario made for a difficult morning commute -- which initially led to several school bus delays and cancellations across the region.
There will be no student transportation this morning (Thursday, Feb 15) because of fog - buses will run this afternoon
