As Ontario grapples with severe winter weather, snow squalls have begun shifting south on Sunday, leading to difficult travel conditions across the province. With forecasters already on high alert for the next wave of snowfall set to hit the area this week, residents are bracing for more challenges ahead.

This brutal lake-effect snowstorm, fueled by icy winds from Lake Huron and Georgian Bay, has already left communities like Echo Bay blanketed under more than 100 cm of snow, and total accumulations are expected to rise throughout the week. The relentless bands of snow have particularly pummeled regions like Gravenhurst and Bracebridge, prompting concerns for drivers and emergency services alike.

A Welcome Break for Some Areas

Fortunately, a change in wind direction to the northwesterly will finally push the intense snow bands south, which means the Greater Toronto Area (GTA) could start feeling the effects later in the day. However, communities along the Lake Huron coast aren't out of the woods just yet, with an additional 50 to 75 cm of snow predicted through Tuesday. As a result, road closures remain a real possibility.

Travel Advisory and Emergency Measures

Travel conditions are expected to become increasingly treacherous. Authorities urge residents to stay updated with the latest radar and highway conditions before setting out. Currently, Highway 11's northbound and southbound lanes remain closed between Highways 169 and 118 due to ongoing emergency response efforts. Reports highlight that numerous vehicles are stranded, and services are racing against time to reach those in need.

Mayor Heidi Lorenz of Gravenhurst has declared a state of emergency for the community, citing severe snowfall and protracted roadway closures as major concerns.

What Lies Ahead

As another wave of chilly air descends over the Great Lakes, more snow squalls are anticipated. While snowfall rates may not match the staggering totals from the weekend, conditions will remain unpredictable. The shift in wind direction is expected to bring squalls into the GTA, transforming local road conditions dramatically. Late afternoon and evening on Sunday will likely see flurries or brief bursts of snow.

Looking forward to Monday, the northeastern regions of Georgian Bay and Lake Huron are set to experience the brunt of the incoming squalls. Cities such as London, Goderich, and Collingwood will need to brace for significant snowfall, while the potential for chaos in the GTA may lessen.

A Silver Lining for Ski Resorts

On a brighter note, the substantial snowfall bodes well for Ontario's ski resorts, which are gearing up for one of their best early December seasons in years. Fresh powder and excellent conditions for snowmaking may attract winter sports enthusiasts eager to hit the slopes.

As we look ahead to Tuesday, relief is in sight as the snow squalls begin to taper off, although residents are cautioned that weather conditions could remain volatile, keeping everyone on their toes as winter fully settles in.
