Environment Canada has issued a yellow weather warning for the Exeter, Goderich, Bluewater and southern Huron County area as a stretch of dangerous winter weather moves in.
A prolonged period of very cold wind chills is expected, with values dropping to between minus 30 and minus 35 overnight tonight and into Saturday morning. In some areas, those extreme wind chills could return again Saturday night into Sunday morning. Extreme cold can be dangerous for everyone, especially young children, seniors, people with chronic health conditions, those who work or exercise outdoors, and anyone without proper shelter. Frostbite can develop in just minutes on exposed skin.
Residents are being reminded to dress warmly, cover exposed skin, and watch for signs of cold-related illness such as numbness, changes in skin colour, muscle pain, weakness, shortness of breath or chest pain. People are also encouraged to check in on older family members, friends and neighbours during the cold spell.
At the same time, a yellow advisory for blowing snow is also in effect for the region. A low-pressure system moving into the area is expected to bring snowfall beginning this afternoon and continuing into tonight. General snowfall amounts of 4 to 8 centimetres are expected, with areas near the Lake Huron shoreline possibly seeing up to 15 centimetres by Saturday morning due to lake-effect snow. Strong northwesterly winds, with gusts reaching up to 80 kilometres per hour, are forecast to develop behind the system, leading to widespread blowing snow and significantly reduced visibility. In some exposed areas, visibility could drop to near zero.
Travel conditions are expected to be hazardous, and road closures are possible if conditions worsen. Environment Canada says an upgrade to a blizzard warning may be needed, depending on how strong and long-lasting the winds become. Drivers are advised to consider postponing non-essential travel and to carry emergency supplies in their vehicles, including extra blankets and jumper cables. Anyone who becomes stranded is urged to stay with their vehicle until conditions improve.
