Avalanche Forecast

MONDAY NIGHT - Flurries, 10-15 / moderate to strong southwest wind / alpine low temperature near -6 / freezing level 1000-1500 m and dropping back down to valley bottom overnight in most areas 

TUESDAY - Flurries, 5 cm / moderate southwest wind / alpine high temperature near -8

WEDNESDAY - Mainly sunny / light northwest wind / alpine high temperature near -9 

THURSDAY - Mainly cloudy with a few flurries / moderate to strong southwest wind / alpine high temperature near -6

Reactive storm slabs are expected to be widespread on Tuesday, and human triggered avalanches are likely, especially in wind loaded areas.

At the time of publishing, there were a few reports of size 1-2 natural and explosives triggered avalanches near Pemberton on Monday.

There were several reports of size 1-1.5 natural and human triggered avalanches in the region on Sunday.

The region has seen 30-60 cm of new snow over the past few days, with another 5 cm expected during the day on Tuesday. 

This 30-60 cm of fresh snow sits on a recently buried persistent weak layer that consists of facets at upper elevations, surface hoar in some sheltered areas, a melt-freeze crust below 1600 m, and a sun crust on south-facing slopes.

In the south, the underlying snowpack is well consolidated. In the north, a melt-freeze crust from early December may be found 100 to 200 cm deep. Recent reports suggest that this layer is gaining strength and it has been unreactive in recent weeks.

• Use conservative route selection. Choose simple, low-angle, well-supported terrain with no overhead hazard.
• Avoid freshly wind loaded terrain features.
