Officials urged drivers to stay off regional highways in much of western Newfoundland and southern Labrador on Thursday morning, as the area remained under a blizzard warning.
The highway connecting Burgeo with the Trans-Canada Highway was blocked with snow, a government advisory said.
The Department of Transportation said several regional highways, including on the Northern Peninsula and near the southern Labrador communities of St. Lewis and Cartwright, were too dangerous for travel.
Marine Atlantic temporarily kept its ferries off the Gulf of St. Lawrence on Thursday morning. The MV Apollo, which serves the Strait of Belle Isle, was also docked.
Numerous schools in western and central Newfoundland were closed for at least the morning.
Environment Canada kept much of central Newfoundland under a winter storm warning, in the wake of a storm that swept into the island on Wednesday with great force.
In eastern Newfoundland, a wind warning was in effect.
