Avalanche Forecast

Consider avalanche danger to be HIGH in areas that receive rain on top of 30 cm or more of dry snow. Avoid exposure to avalanche terrain during periods of rapid loading by rain, snow, or wind.

Travel and Terrain Advice
- Avoid exposure to avalanche terrain during periods of rapid loading by rain, snow, or wind.
- Watch for signs of instability such as whumpfing, cracking, or recent natural avalanches.
- Use conservative route selection, choose moderate angled and supported terrain with low consequence.
Avalanche Problem 2: Loose Wet
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Rain falling on dry snow can quickly trigger natural avalanches.
Travel and Terrain Advice
- Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.
Avalanche Problem 3: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Rapid loading by rain or snow will increase the likelihood of avalanches occurring on this layer.
Travel and Terrain Advice

Avalanche Summary
On Friday, no new avalanches were reported in this region. Natural avalanche cycle expected on Sunday in areas where rain falls on dry snow. We currently have very limited observations in this region. Please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
A new crust was formed on Thursday as temperatures cooled and the rain soaked snow surface froze and then was covered by 5-10cm of snow at treeline and above. Wind re-distributing this new snow may have formed small wind slabs on lee features, such as below ridgetops and in gullies. The depth of the snowpack varies greatly with elevation. Recent reports suggest the average depth is 200+cm in the alpine, 100-150cm at treeline, and decreasing rapidly below treeline where the primary hazards are rocks, stumps, and open creeks. The major feature in the snowpack is a crust which was formed around November 11th and can be found approximately 100cm down at treeline elevations. We currently have very limited snowpack observations within this region and it is critical to supplement this information with your own observations.
Weather Forecast
SUNDAY: 5-15mm rain or snow depending on elevation / Moderate to strong westerly ridgetop winds / Freezing level rising to around 2200 m
MONDAY: Cloudy with isolated flurries / Light to moderate westerly ridgetop winds / Freezing level around 1200 m
TUESDAY: 5-10 cm of snow / Light to moderate westerly ridgetop winds / Freezing level around 1500 m
