Thick fog is blanketing much of the capital region Monday morning as well as surrounding areas.

Environment Canada has issued a fog advisory for the City of Winnipeg and portions of the Red River Valley and Interlake regions. 

Mild temperatures and high humidity have resulted in reduced visibility in several areas and is affecting travel. Motorists are reminded to drive according to the conditions and be on alert for tail lights ahead of them. 

The mild conditions have also caused some city roads, as well as highways, to become ice-covered. Drivers should especially be mindful of icy conditions while travelling on bridges and overpasses.

Manitoba Infrastructure is reporting ice-covered roads on the South and East Perimeter Highways and Highway 59 from Winnipeg to the U.S. border. More reports are likely to come in as the morning progresses.

The fog is expected to clear late Monday morning, making way for a mix of sun and cloud, and a high of -3. 

Overnight, more clouds are expected to move in, and heavy fog is expected to develop once again.
