Points saillants

New snow may need time to bond.

Investigate on small, safe features before committing to big terrain.

Problèmes avalancheux

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2

    Storm slabs may still be triggerable in steep terrain. Test the bond on small, safe features before committing to your line.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1–1.5

    If the sun comes out, it will likely trigger wet loose avalanches on steep sunny slopes, especially in areas where new snow is seeing sun for the first time.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Make observations and continually assess conditions as you travel.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Storm slabs are suspected to have occurred on Thursday and are likely to decrease in sensitivity moving into Friday.

On Tuesday, a rider triggered a large (size 2) storm slab that carried them a long way on the crust from March. They were uninjured. This occurred east of New Denver.

Snowpack Summary

Around 10 to 20 cm of new snow fell on Thursday, which sits on a thin melt freeze crust.

A thick crust is buried 30 to 40 cm deep, which makes it unlikely to trigger any weak layers that persist in the upper snowpack.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.
