Canada: Adverse winter weather conditions forecast across southeastern regions through at least early Jan. 7

Adverse winter weather conditions are forecast over parts of southeastern Canada through at least early Jan. 7. A low-pressure system affecting parts of southeastern Labrador, northern Newfoundland, and southeastern Quebec is expected to continue to bring strong winds and heavy snowfall to the region Jan. 6. Similar conditions are expected across parts of eastern Nova Scotia, central and eastern Prince Edward Island, and the Magdalen Islands in Quebec through late Jan. 6-early Jan. 7. Snowfall accumulations of 5-35 cm (2-14 inches) are expected across the region, with localized heavier amounts over elevated areas. Winds gusting up to 100 kph (62 mph) are also expected across the affected area. Hazardous travel conditions are likely across the region due to reduced visibility caused by blowing snow.

As of early Jan. 6, Environment Canada has issued the following warnings:

• Red winter storm warnings (the highest level on a three-tier scale): Parts of southeastern Labrador, northern Newfoundland, northeastern Nova Scotia, eastern Prince Edward Island, and the Magdalen Islands in Quebec.

• Red win warnings: Parts of northern Newfoundland, eastern Nova Scotia, and southeastern Quebec.

• Grey special weather statements for snow, strong winds, and blowing snow: Parts of eastern Nova Scotia and central Prince Edward Island.

Officials could update and extend the coverage of weather alerts over the coming hours and days.

Snow accumulations are likely across the affected region, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation is less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Sporadic power outages could occur throughout the affected region.

The winter weather will likely cause disruptions to ground and air transport across the region. Traffic and commercial trucking delays are probable along regional highways. Dangerous and challenging driving conditions are likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities will probably close stretches of highways if driving conditions become too hazardous. Flight delays and cancellations are likely due to ground stops and deicing operations at regional airports.
