Heavy rain, snow, and strong winds are certain to elevate avalanche danger ratings in upper elevation terrain.

Confidence
High
Avalanche Summary
There have been no recent avalanche reports in the region.
Increasing snowfall mixed with rain and strong southwest wind are certain to induce a natural avalanche cycle.
If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).
Snowpack Summary
New snow mixed with rain will bury a firm crust at treeline and will become increasingly unstable as the new snow rapidly gets deeper. North through east-facing slopes in the alpine may have buried surface hoar which sits over moist snow.
Snow depths at treeline vary across the region from 65 cm to 150 cm.

Terrain and Travel Advice
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Loose avalanches may start small, but they can grow and push you into dangerous terrain.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
Problems
Loose Wet
As rain begins to unconsolidated and weaken the upper snowpack , expect naturally trigger avalanches to occur on all aspects and at elevations below 1700 m.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
