Avalanche Forecast

Moderate - Uncertainty is due to the limited number of field observations.

TUESDAY NIGHT - Mainly cloudy with a few flurries, up to 5 cm / light southwest wind / alpine low temperature near -6 

WEDNESDAY - Mainly cloudy with flurries, 5-10 cm / moderate southeast wind / alpine high temperature near -6

THURSDAY - Mainly cloudy / moderate southeast wind / alpine high temperature near -5 

FRIDAY - Flurries, 5-10 cm / moderate southwest wind / alpine high temperature near -6

Human triggered avalanches are expected to remain likely on Wednesday, especially in wind loaded areas.

At the time of publishing, there were a few explosives triggered storm slab avalanches to size 2 reported on north aspects in the alpine, in the north of the region.

On Monday, there were reports of widespread natural and explosives triggered avalanches up to size 3. The largest avalanches were reported in the north of the region where there has been more recent snow. The avalanches being reported closer to Terrace were generally in the size 1-2 range.

There were a few natural and explosives triggered storm slab avalanches size 1-2.5 reported in the region on Sunday.

With continued flurries Tuesday night and into Wednesday, storm slabs will likely continue to be reactive to human triggers at all elevations.

Aside from this new snow, the main concerns vary throughout the region. In the Shames area, a weak layer of surface hoar has been reported in sheltered areas down around 100-160 cm. 

A bit further north in the Nass/Sterling/Beaupre areas, there is potentially still concern about an older weak layer overlying a crust that is now roughly 160-180 cm deep. 

In the far north of the region, there is concern about weak snow at the bottom of the snowpack.

• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Avoid freshly wind loaded terrain features.
• Storm slabs in motion may step down to deeper layers resulting in large avalanches.
