Avoid all avalanche terrain.
Buried weak layers combined with a lot of new snow mean avalanche conditions are very dangerous.

High
Avalanche Summary
New snow and wind are forecast which will lead to an increase in avalanche size and likelihood this weekend. Large storm slabs and persistent slabs are expected.
Snowpack Summary
The storm continues, and is expected to total 30 to 50 cm by the end of the day on Sunday.
Underneath the new snow is a melt-freeze crust that extends to ridge top on all aspects, except northerly slopes above 1700 m.
A weak layer formed in February, consisting of facets, surface hoar, or a crust, is found 30 to 60 cm deep. Additional weak layers formed in January are present within the upper 100 cm of snow, including faceted snow, crusts on south-facing slopes, and surface hoar in shaded terrain.
The mid and lower snowpack is generally well-settled and strong.

Terrain and Travel Advice
- Avoid avalanche terrain during periods of heavy snowfall.
- Avoid the runout zones of avalanche paths. Avalanches could run full path.
- Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
Problems
Storm Slabs
Storm slabs are developing as the new snow piles up. The more new snow there is, the more likely and dangerous storm slabs are.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
Weak layers from January and February persist within the upper 100 cm of snow. New snow will increase the likelihood of persistent slab avalanches.
