Authorities urged drivers in different areas of Newfoundland to stay off the roads, as snow squalls hit the west coast and visibility was so low on one stretch of the Avalon Peninsula that a regional highway was closed.

The Department of Transportation shut down the road on the Heart's Content Barrens, which the RCMP described as "totally impassable." Police noted that visibility in the area was poor.

On the west coast, snowplows were temporarily hauled off the Trans-Canada Highway between Corner Brook and Stephenville, as well as the Stephenville access road.

Authorities urged drivers on the Port au Port Peninsula to stay off the road between Piccadilly and Mainland.

Extreme caution was also being urged on roads in the Bay St. George area, including in and around Stephenville.

Temperatures across the province were cold on Wednesday, with icy roads reported on the heels of a warm-up on Tuesday that included rain and melting snow.

In western Labrador, the wind chill was so low that classes for primary school children were cancelled for the morning.
