Alerts for: Gros Morne

Watches

11:36 PM NST Thursday 02 February 2023
Snow squall watch in effect for:

  • Gros Morne

A period of intense snow squalls producing blizzard-like conditions is expected.

Time span: Friday night until Sunday morning.

Preceding snowfall expected on Friday: near 10 cm.
Snowfall Friday night through Sunday morning: near 10 cm, except locally 20 to 30 cm in snow squalls.

Maximum wind gusts: westerly 80 to 100 km/h on Saturday.

Locations: Plum Point to Channel-Port aux Basques.

Remarks: After a period of snow and relatively mild temperatures under southeasterly flow on Friday, temperatures will fall rapidly on Friday night as a very cold southwesterly flow of arctic air is ushered into western Newfoundland. Intense snow squalls are expected to develop, and will persist through Saturday into Sunday morning.

Additionally, extremely cold temperatures and strong winds will combine to cause dangerously low wind chills on Saturday.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Consider postponing non-essential travel until conditions improve.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NLstorm@ec.gc.ca or tweet reports using #NLwx.
