Lo esencial

Avalanche activity will increase with sun and warming, especially if there is no overnight freeze.

Minimize your exposure to cornices, and steep south-facing slopes in the heat of the day.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–2.5

    Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–1.5

    Rising temperatures and strong sunshine will increase the potential for wet avalanches. Warming will be most intense on steep south-facing slopes, especially near rocks.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported on Thursday, but expect an increase in avalanche activity with the upcoming warming on Friday.

Evidence of past avalanches, such as this one observed Saturday on Sky Pilot, may still be visible in the region.

NOTE: Recent observations are currently very limited in this region.

Thanks for sharing to the Mountain Information Network if you are going into the backcountry.

Snowpack Summary

A typical spring diurnal cycle is underway.

High freezing levels have transformed the surface during the day into moist snow, while cooling at night has formed a crust.

The snowpack is generally well-settled and strong.

Lower elevations are melting out rapidly.

Weather Summary

Thursday Night

Clear. 10 to 20 km/h north ridgetop wind. Treeline temperature 8 °C. Freezing level 2800 m.

Friday

Mostly sunny and increasing cloudiness. 20 to 30 km/h west ridgetop wind. Treeline temperature 12 °C. Freezing level 3300 m.

Saturday

Mostly cloudy with isolated flurries. 20 to 30 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 1700 m.

Sunday

Mostly cloudy with isolated flurries. 30 to 40 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid travelling on slopes below cornices.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Avalanche danger will increase as the surface crust breaks down.
