Blowing snow made it hard to see along a road in Barrie, Ont. CTV News
Residents across Simcoe County face a blast of harsh winter weather as Environment Canada warns of strong snow squalls expected to last from Sunday afternoon through Monday morning. The alert, issued just after 9 a.m. on Sunday, calls for heavy lake-effect snow and rapidly changing conditions across the region.
Snowfall Totals Could Rise Quickly
Forecasters say snowfall amounts will range from 15 to 30 centimetres. Areas under the strongest and most persistent snow bands coming off Georgian Bay could see the highest totals. These bands often shift quickly and intensify without warning, making travel conditions unpredictable.
The system may strengthen through the afternoon and into the evening. Sudden bursts of heavy snow can create whiteout conditions with almost no visibility. Roads may become slick and hard to navigate, and officials warn that closures could occur in some areas.
Travel Risks Increase
Drivers across Simcoe County should plan for challenging travel and slow commutes. Blowing snow, low visibility, and rapid weather changes can occur within minutes. Transportation crews expect to remain busy throughout the storm, but the intensity of the snow bands could make conditions dangerous at times.
Officials advise motorists to carry emergency kits, keep headlights on, and avoid unnecessary travel during peak squall periods. They also encourage drivers to stay alert for road advisories and closures announced by local authorities.
Conditions Improve Monday
Environment Canada expects the snow squalls to weaken by Monday afternoon. Lighter flurries may continue into midday, but visibility and road conditions should slowly improve as the system shifts away from the region.
Even after the squalls ease, roads may remain snow-covered and slippery. Residents are encouraged to give themselves extra time for travel on Monday morning.
Stay Informed and Stay Safe
Officials urge the public to monitor weather alerts and follow instructions from local road and emergency crews. Snow squalls can form and intensify suddenly, making it important to stay aware of conditions throughout the storm.
Environment Canada reminds residents that lake-effect snow often changes direction and strength without warning. People across Simcoe County should stay prepared for fast-moving snowfall and hazardous travel.
