Highlights

Now is a great time to explore more committing alpine objectives.

Continue to use caution: Daytime warming may cause loose wet sluffing and weaken cornices.

    Wet loose activity may be possible if the sun and warming melt the surface crust. This will be most likely to occur on steep sunny slopes.

Confidence

High

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

Avalanche Summary

Some small wet loose sluffs and cornice falls have been reported in the region in the last couple of days, but no significant avalanche activity has been reported since last Tuesday.

Conditions are spring-like: If daytime warming weakens the surface crust, wet loose avalanches may become possible. Cornices are large and fragile and may also be impacted by the warming.

Snowpack Summary

Many areas have rain runnels or sun cups. In general, a hard surface crust extends to mountain top on all aspects and elevations.

The crust may break down during daytime warming, and if well timed, provide some good riding conditions. The potential for wet loose avalanches and cornices falling will also increase with sun and warming.

Cornices are large and fragile following the last storm. Be mindful of them during this warming trend.

Otherwise, the snowpack is well consolidated, with multiple crusts and rounded grains, with no additional layers of concern.

Terrain and Travel Advice

  • Periods of low danger may be a good time to increase your exposure.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
