Residents across the region are being urged to take extra precautions today as Environment Canada has issued both a Yellow Warning for extreme cold and a Yellow Advisory for blowing snow, creating potentially dangerous travel and outdoor conditions.
Meteorologists say wind chill values this morning are expected to range between minus 25 and minus 30, with brisk winds gusting up to 50 kilometres per hour. While conditions are expected to ease slightly through the afternoon, wind chills will remain near minus 20, and could once again dip into the minus 25 to minus 30 range overnight into Wednesday morning.
At the same time, a blowing snow advisory is in effect due to strong southwesterly winds gusting between 50 and 70 kilometres per hour, which are expected to cause significantly reduced visibility in some areas. Forecasters say blowing and drifting snow will be most pronounced in open and wind-exposed areas, including along the Lake Erie shoreline, making travel especially hazardous. Winds are expected to shift to a westerly direction later this afternoon and into the evening.
Environment Canada warns that extreme cold poses a risk to everyone, but especially young children, seniors, people with chronic illnesses, outdoor workers, and those without adequate shelter. Frostbite can develop within minutes on exposed skin, particularly when combined with strong winds.
Health officials are advising residents to watch for cold-related symptoms such as shortness of breath, chest pain, muscle weakness, numbness, or colour changes in fingers and toes. Anyone experiencing these symptoms should move indoors immediately and begin warming up.
Drivers are also being reminded to keep emergency supplies in their vehicles, including extra blankets, food, and jumper cables, in case of breakdowns or poor road conditions. With near-zero visibility possible at times, officials say travel may be difficult or unsafe, and motorists should allow extra time or avoid unnecessary trips altogether.
Outdoor workers are encouraged to take frequent warm-up breaks, dress in layers, and cover exposed skin to reduce the risk of frostbite and hypothermia as this stretch of severe winter weather continues.
