Heavy Snow Squalls Sweep Across Southern Ontario

Right now, much of southern Ontario is being hit by fast-moving, intense bursts of winter weather, and a lot of it is tied to lake-effect snow rolling in from Lake Huron and Georgian Bay. These systems have been strengthening through the day, and as a result, broad yellow and orange weather alerts have been issued under Environment Canada’s new colour-coded warning system. It’s all meant to help people understand the level of risk at a glance, and today’s colours are definitely sending a message.

A yellow alert has been put in place for areas stretching from the South Bruce Peninsula through communities like Tobermory and Feversham. Under this level, people are being told to be prepared for sudden drops in visibility and travel delays. Winds are expected to hit up to 80 km/h, and when those gusts pick up loose snow, visibility can go from clear to near zero in seconds. It’s the kind of weather where even a familiar drive can feel unpredictable.

But the more serious concerns are tied to the orange alerts issued across a large portion of the snowbelt, including Barrie, Orillia, Aurora, and Collingwood. Under orange warnings, weather is considered severe enough to cause major disruptions, and that’s exactly what meteorologists are expecting. Snowfall could reach a staggering seven centimetres per hour in the most intense bands, and totals may climb to 50 centimetres in some communities. With wind gusts around 70 km/h, whiteout conditions and drifting snow are almost guaranteed. In some cases, highways may need to be shut down, not because the snow depth is overwhelming, but because drivers simply won’t be able to see the road ahead.

Even the Greater Toronto Area isn’t completely spared. The western, northern, and eastern edges of the GTA are expected to see brief but intense bursts of snow. The accumulation won’t be nearly as high as what’s happening north of the city, but there will still be moments where visibility drops sharply. Because temperatures are hovering just above freezing, some of that snow may melt on contact, but that doesn’t eliminate the risk of slick roads or sudden low-visibility pockets.

Further east, Ottawa is expected to avoid the worst of this storm, although some flurries and passing snow showers are likely. The storm’s core is tracking north and west of the capital, leaving Ottawa with lighter impacts compared to communities in the heart of the snowbelt.

Across southern Ontario, people under yellow or orange alerts are being urged to take travel precautions seriously. With rapidly shifting conditions, strong winds, and potential road closures, it’s a day to slow down, stay aware, and keep an eye on updated forecasts as the system continues to evolve.
