Canada: Adverse winter weather forecast across Newfoundland through at least Dec. 6

Adverse winter weather conditions are forecast across Newfoundland through at least Dec. 6. A storm system moving over the region Dec. 5-6 is expected to bring strong winds and a mix of snowfall and rainfall across Newfoundland. As of early Dec. 5, Environment Canada has issued red snowfall warnings (the highest level on a three-tier scale) for parts of central and western Newfoundland; snowfall accumulations of 5-15 cm (2-6 inches) are expected in these areas. Red strong wind warnings are in place across eastern, northern, southern, and western Newfoundland; winds gusting over 100 kph (62 mph) are possible in exposed coastal areas. Officials could update and extend the coverage of the weather alerts and/or issue new alerts over the coming days.

Strong winds may cause fallen tree branches, power outages, damage to buildings, and ferry service disruptions in the short term. The gusts may also cause periods of blowing and drifting snow in some locations, with blizzard conditions possible in places.

The winter weather will likely cause ground and air transport disruptions over the coming hours. 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 areas as maintenance crews will probably 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. Heavy, wet snow and strong winds could bring down power lines and trees with foliage.
