Adverse winter weather forecast across parts of eastern Canada through at least early March 21. Hazardous travel conditions likely.

Warning

Event

Adverse winter weather is forecast across parts of eastern Canada through at least early March 21. Snowfall accumulations exceeding 70 cm (28 inches) and winds gusting up to 100 kph (62 mph) are possible across parts of Newfoundland and Labrador, far eastern Nova Scotia, and far eastern Quebec on March 20 and overnight through early March 21. The combination of heavy snow and strong winds will likely lead to blizzard conditions across parts of the affected area. Hazardous driving conditions are likely across the affected area due to icy roads and reduced visibility caused by blowing snow.

As of early March 20, Environment Canada has issued red snowfall and blizzard warnings across parts of eastern and central Labrador and red strong wind warnings are in place across parts of eastern Newfoundland, far eastern Nova Scotia, and far eastern Quebec. Grey blowing snow advisories are in place across parts of western Newfoundland. Officials will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

Snow accumulations are likely across the affected area. Lesser snowfall totals are possible where sleet and freezing rain mix with snow. In addition to the heavy snow, strong wind gusts will probably lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are possible throughout the affected area.

The inclement weather will likely cause widespread ground and air transport disruptions across the affected area. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also probable on secondary and rural roads in the affected provinces as maintenance crews prioritize clearing major routes. Authorities could close stretches of highway if driving conditions become too hazardous. Gusty winds may threaten to topple high-profile vehicles throughout the affected area. Mountain passes and tunnels could be closed as a precautionary measure during periods of intense snowfall. The disruptive weather will likely cause some delays and cancellations at airports in the affected region. Heavy wet snow and strong winds could bring down power lines and trees with foliage.

Advice

Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall is forecast. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. If routing shipments by truck through the affected area, plan accordingly for delivery delays. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
