In sintesi

Avalanche danger is low where a hard crust is on the snow surface. Continue practicing safe travel habits, such as giving cornices a wide berth and limiting exposure on steep, slushy slopes.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–2.5

    Cornices remain large and they could release unexpectedly during the heat of the day.

Confidence

High

  • The snowpack structure is well understood.

Avalanche Summary

A widespread cycle of wet loose and slab avalanches occurred over the past few days with intense warming. They occurred on all aspects and at all elevations.

Looking forward, avalanche activity is not expected anywhere a thick and hard melt-freeze crust is on the snow surface. Continue to use caution travelling near cornices and on sun-exposed slopes during the heat of the day.

Snowpack Summary

Cool weather will freeze all the recent wet snow to mountain top into a hard melt-freeze crust. A dusting of snow may fall onto this crust this, particularly for the Selkirks. The snow surface may moisten on sun-exposed slopes and below treeline with daytime warming.

The remainder of the snowpack is strong, with various thick melt-freeze crusts found in the upper to middle portions of the snowpack.

The snowpack continues to melt below treeline.

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.
  • Be alert to conditions that change with aspect and elevation.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
