Severe Snow Squalls Expected Across Ontario

As Ontario braces for a significant winter weather event, residents are urged to prepare for heavy snowfall and dangerous travel conditions as snow squalls are set to roll through the region. With forecasts indicating potential accumulations of 30 to 80 cm in some areas, the situation could escalate quickly. Here’s what you need to know.

Current Weather Warnings

Environment Canada has issued blizzard warnings for areas including Grey County, northern Huron County, and southern Bruce County. Blizzard warnings are activated when winds exceed 40 km/h, causing visibility reductions to 400 metres or less due to blowing snow.

In addition to the blizzard warnings, a snow squall watch has been implemented for regions including Barrie, Orillia, and Midland, with expectations of poor visibility and hazardous conditions due to heavy snowfall.

What to Expect

Meteorologists report that a deepening low-pressure system from the East is combining with Arctic air to create sustained snow squalls across Ontario from Wednesday night through Friday. This combination will lead to:

• Local accumulation of 30 to 50 cm in low-lying and snowbelt areas, with isolated totals potentially exceeding 80 cm.
• Peak snowfall rates of up to 10 cm per hour, particularly in areas directly affected by the lake-effect snow.
• Winds gusting from the west reaching up to 80 km/h, which could further reduce visibility, creating whiteout conditions.

Areas Affected

Key areas likely to experience the most intense snowfall include:

• Goderich to Tobermory
• Barrie and surrounding regions
• Georgian Bay’s shorelines
• Parts of the Greater Toronto Area (GTA)

Travel advisories are in effect, as road conditions could deteriorate rapidly. Major routes, especially Highway 21 and Highway 400, may experience closures due to extreme conditions.

Safety Tips for Travelers

If you must travel during this weather event, keep the following safety tips in mind:

• Stay informed of the latest weather alerts. Check forecasts regularly as conditions can change quickly.
• Avoid unnecessary travel until conditions improve. If you must go out, inform others of your plans and carry an emergency kit, including food, water, and a fully charged cell phone.
• Be prepared for limited visibility and potentially stranded conditions. Dress warmly and keep blankets in your vehicle.

The Weather Outlook

Following this frigid spell, temperatures are expected to rise slightly with a three-degree increase over the weekend, providing a brief respite from the cold. However, further cold fronts may return next week, leading to additional snow events as we approach the holidays.

In summary, as significant lake-effect snow squalls are poised to hit Ontario, residents must stay alert and comprehend the possible impacts on travel and daily life. By staying informed and prepared, you can navigate this winter weather safely.

Conclusion

With the forecast indicating a rollercoaster of weather conditions, maintaining awareness and preparation is vital for ensuring safety during this challenging and potentially hazardous snow squall event.

Keep checking for updates to stay on top of the changing conditions throughout this winter storm. Stay safe, Ontario!
