Fog advisory issued by Environment Canada
Environment Canada has issued a fog advisory for parts of Ontario, warning of reduced visibility and hazardous driving conditions on Christmas Day. The advisory covers areas such as Orillia, Midland, Barrie, and Collingwood. The fog is expected to persist until Saturday morning, when it will gradually dissipate.
According to Environment Canada, the fog is caused by a warm and moist air mass over a cold snow-covered ground. The fog may become dense in some areas, reducing visibility to less than 200 metres. Drivers are advised to slow down, keep a safe distance, and use low-beam headlights.
Lake effect snow adds to the challenge
In addition to the fog, some areas of Ontario are also experiencing lake effect snow, which can further reduce visibility and create slippery road conditions. Lake effect snow is expected to intensify on Friday morning and shift eastward by Friday afternoon. Total snowfall amounts near 10 cm are possible by Friday evening.
Lake effect snow occurs when cold air passes over warmer lake waters, picking up moisture and forming clouds that produce snow downwind of the lakes. The snow bands are often narrow and localized, but can produce heavy snowfall in a short period of time.
Travel impacts and tips
The fog and snow have created challenges for travellers in Ontario, especially during the holiday season. Some flights have been delayed or cancelled at Toronto Pearson International Airport due to the weather conditions. Travellers are advised to check their flight status before heading to the airport.
For those who are driving, the Ministry of Transportation provides information on road conditions, closures, and incidents through its website, Twitter account, or phone service (5-1-1). Drivers should also prepare an emergency kit, check their vehicle’s tires and fluids, and plan their route ahead of time.
Stay safe and enjoy the holidays
Despite the weather challenges, many Ontarians are still finding ways to enjoy the holidays. Some are staying indoors and cozying up with their loved ones, while others are venturing out to see the festive lights and decorations. Some are also taking advantage of the snow and engaging in winter activities such as skiing, snowshoeing, and sledding.
Whatever your plans are, remember to stay safe and follow the public health guidelines to prevent the spread of COVID-19. Wear a mask, wash your hands, and keep a physical distance from others. We wish you a merry Christmas and a happy new year!
