Residents of Simcoe County are bracing for a significant blast of winter weather as Environment Canada issues a warning for intense snow squalls expected to blanket the region. The federal weather agency forecasts that these localized but powerful bands of snow could deposit up to 30 centimetres of fresh snow, creating potentially dangerous conditions.
Hazardous Travel Conditions Expected
The primary concern with the incoming snow squalls is the dramatically reduced visibility. Blowing snow will create whiteout conditions at times, making travel extremely hazardous. This is particularly true for motorists on highways and rural roads in the affected areas. Environment Canada has emphasized that visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.
The warning, issued on the afternoon of Sunday, November 16, 2025, highlights the sudden and intense nature of this weather phenomenon. Snow squalls are notorious for their ability to rapidly accumulate snow in a very short period, often catching drivers off guard.
Key Details and Regional Impact
The core of the snow squall activity is expected to target regions including Barrie, Orillia, and surrounding parts of Simcoe County. The forecast suggests that the heaviest snowfall rates will occur Sunday evening and persist into Monday.
In addition to the heavy snow accumulation, strong westerly winds are anticipated to accompany the squalls, which will whip the falling snow into the air and cause significant drifting. This combination of factors leads to the dangerously low visibility that defines a snow squall event.
Staying Safe During the Squalls
Environment Canada and local authorities are urging residents to reconsider any non-essential travel during the peak of the snow squall activity. If travel is absolutely necessary, drivers are advised to be prepared for rapidly changing road conditions.
It is recommended to have a winter survival kit in your vehicle, including a blanket, flashlight, and extra warm clothing. Motorists should slow down, turn on their full headlights and taillights, and maintain a safe following distance. Staying informed with the latest forecasts and warnings from Environment Canada is crucial, as the trajectory and intensity of snow squalls can shift quickly.
This early-season weather event serves as a stark reminder that winter has arrived in Southern Ontario, prompting residents to ensure they are prepared for the months ahead.
