Avalanche Summary
Small wet and dry loose avalanches continue to be triggered by skiers in steep terrain.
Snowpack Summary
During the day on Friday the snow surface will become moist on all aspects and elevations except for high north facing terrain, where up to 30 cm overlies a crust from late March. Below these crusts, the upper snowpack is moist.
Several weak layers from early March, mid February and late January can be found in the mid and lower snowpack.
The remainder of the snowpack is generally well settled.

Terrain and Travel Advice
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
- Make observations and continually assess conditions as you travel.
- Avoid travelling on slopes below cornices.

Wet loose avalanches are possible on sun exposed slopes and at lower elevations.
Dry loose avalanches are possible where new snow hasn’t formed a slab or become moist.
Aspects: All aspects.
