Environment Canada is warning residents in Exeter, Goderich, Bluewater, and southern Huron County about dangerous winter weather expected to continue through tonight and into Wednesday morning.
Very cold wind chills are forecast, with values dropping between minus 25 and minus 30 overnight. While conditions may ease slightly during the day, wind chills are still expected to stay near minus 20 before becoming colder again late tonight. Environment Canada says extreme cold can affect everyone, but the risk is higher for young children, seniors, people with chronic health conditions, those who work or exercise outdoors, and anyone without proper shelter.
People are being reminded to dress warmly and cover exposed skin, as frostbite can develop in just minutes. Symptoms of cold-related illness can include numbness, colour changes in fingers or toes, muscle weakness, chest pain, and shortness of breath. Anyone showing signs of frostbite or hypothermia should move indoors and begin warming up right away. Drivers are also encouraged to keep emergency supplies in their vehicles, including blankets.
At the same time, blowing snow and snow squalls are creating hazardous travel conditions across the region. Strong winds gusting up to 50 kilometres per hour are causing blowing and drifting snow, especially in open areas. Visibility may drop to near zero at times, making travel difficult and dangerous. Snow squalls off Lake Huron are expected to bring heavy snow and reduced visibility from this afternoon through Wednesday morning, with local snowfall amounts of 10 to 20 centimetres possible.
Environment Canada warns that road conditions can change quickly, and drivers may encounter sudden whiteout conditions. Road closures are possible, and residents are being urged to delay travel if conditions worsen.
People are encouraged to continue monitoring weather alerts and forecasts from Environment Canada as conditions evolve.
