Highlights

Good skiing can be found out there, however watch for windslabs near ridgetop and persistent slabs on northerly aspect.

If the sun comes out and it warms up, wet loose avalanches will be possible during the heat of the day.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    Wind slabs can be found in isolated locations in the alpine. These developing wind slabs are small in size but be aware that if triggered, they could trigger a persistent slab.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–3.5

    This problem seems to be most active where the March 19th crust is not supportive over the Feb 3rd weak layer (down 30-90cm) of facets over a crust. Northerly aspects between 1900-2400m seem to be the problem area. It is possible that this will step down to the deep persistent weak layer.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    Climbing freezing levels and solar radiation will destabilize the snowpack. Loose wet avalanches are most likely on steep, sun affected slopes. Avalanches may initiate easily on the smooth crust below.

Confidence

Moderate

Avalanche Summary

No new avalanche activity reported on Saturday.

Snowpack Summary

10-15cm of low density snow sits over the March 19th crust which is present everywhere except North aspects above 1900m. The Feb 3rd crust interface is down 30-90cm. Basal depth hoar and facets make up the bottom of the snowpack. HS ranges from 50 to 150cm.

Terrain and Travel Advice

  • Conditions may have improved, but be mindful that deep instabilities are still present.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Be carefull around freshly wind loaded features.
