Once the snow surface turns from hard and crunchy to moist and slushy, wet loose avalanches are possible.

High

• Confidence is due to a stable weather pattern with little change expected.

Minimal avalanche activity is expected in areas where a strong surface crust is present. However, avalanche activity could increase as the crust weakens during daytime warming or where a crust fails to form overnight.

At higher elevations, a surface crust can be found on all aspects with moist snow below. Lower down, the crust may not have formed, and the snowpack is fully saturated.

The mid and lower snowpack are generally well settled. There are no layers of concern at this time. The height of snow at treeline is 100 to 200 cm.

• Avalanche danger will increase as the surface crust breaks down.
• Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
• A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
