Points saillants

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

Continue to use caution: Daytime warming may cause cornices to fall, & loose wet sluffs if the surface crust melts.

    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

No significant avalanche activity has been reported since the most recent storm cycle ended on Tuesday.

If daytime warming weakens the surface crust, wet loose avalanches may become possible. Cornices are large and fragile following the recent storm 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 surface crust may break down during daytime warming, especially on sun-exposed slopes, increasing the potential for wet loose avalanches.

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.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
