Southern Manitobans will be waking up to some foggy conditions on Wednesday morning. Environment and Climate Change Canada (ECCC) issued a fog advisory for several Manitoba communities, including Winnipeg, Portage la Prairie, Selkirk and Steinbach. According to the weather agency, a “dense fog” has developed over the Red River Valley and eastward to the Ontario border. It warns the foggy weather may cause “near-zero visibility;” however, conditions are expected to improve throughout the morning. Drivers are warned that travel may be dangerous in some areas.
