Incoming storm snow over a layer of surface hoar and crust will increase danger to High by the end of Friday.

Avoid travel in avalanche terrain.

• We are uncertain about forecast snowfall amounts.
• We are uncertain due to variable freezing levels.

No new avalanches have been reported in the past week.

We expect new snow building over surface hoar will begin a cycle of natural and human triggered avalanches on Friday.

If you are getting out, please share observations like avalanches, weather and riding conditions to the Mountain Information Network.

Up to 40 cm of new snow is expected to fall through the day on Friday, adding to the 10 to 20 cm of recent snow on a layer of surface hoar over a crust.

This new snow will be accompanied by moderate to strong southwest wind, meaning that the crust will likely remain on the surface on southerly aspects and deeper deposits will be found on north and east aspects. The surface hoar is largest on sheltered treeline and below treeline features

The lower snowpack is well settled.

• Avalanche danger is expected to increase throughout the day.
• Avoid avalanche terrain during periods of heavy snowfall.
• Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
