Choose terrain that is not exposed to overhead hazard and seek out low angle slopes. Be especially cautious during periods of heavy rain or snow.

Avalanche Summary
On Thursday explosive control triggered several small wind slabs (up to size 1.5). Two large (size 2- 2.5) naturally occurring wind slabs were also seen. All occurred on north and westerly aspects.
Snowpack Summary
The snow surface is likely to be wet or moist from rain and warming up to 1500 m.
Recent snowfall amounts across the region range from 30 - 50 cm and have formed into reactive storm slabs.
At upper elevations, strong southwesterly winds have formed reactive wind slabs in leeward north and west facing terrain, while scouring windward slopes.
A layer of facets buried at the end of November can be found near the ground.
The snowpack depth varies between 200 and 300 cm at treeline.
Weather Summary
Friday Night
Light to moderate rain, or snow 5-10 cm, above 1500m, southeast winds 40-50 km/h, treeline temperatures 1 °C, freezing level up to 1600 m
Saturday
Cloudy with light to moderate rain or snow 5-15 cm above 1400 m, southeast winds 30 - 50 km/h, treeline temperature -1 °C, freezing level 1500 m.
Sunday
Mostly cloudy with trace amounts of new snow, south west wind 30 km/h, treeline temperature -7 °C.
Monday
Cloudy with no precipitation, easterly winds 10-20 km/h, treeline temperature -7 °C.

Terrain and Travel Advice
- Avoid exposure to overhead avalanche terrain during periods of heavy loading from new snow, wind or rain.
- Watch for changing conditions today, storm slabs may become increasingly reactive.
- Keep in mind that wet avalanches can be destructive due to their high density.
Problems
Storm Slabs
These slabs are expected to be especially reactive on north and west facing slopes in the alpine and during heavy periods of rain and/or snow.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Loose Wet
This problem will be especially prevalent below 1500 m during periods of rain, and when the snow surface is wet.
