Points saillants

Spring is working its magic on the snowpack with quick settling layers and generally good travel. Snow quality is the trade off with variable ski quality on some aspects. Sheltered north aspects have the best odds for finding good snow.

Problèmes avalancheux

    1.5–2.5

    New windslabs are out there. Watch temperatures tomorrow and try and time your exit to avoid the end of day warmth.

  • Persistent Slabs

    Repeated warming/cooling cycles are helping stabilize these layers. Continue to watch steep polar aspects where the warming cycles are fewer and less intense.

  • Loose Wet

    Solar "greenhouse" cloud effect or direct sun will quickly trigger loose wet avalanches.

Confidence

Avalanche Summary

Nothing was reported or witnessed today, but there was almost certainly a late day loose wet cycle on solar aspects.

Snowpack Summary

The most relevant change to talk about is the arrival of our beloved wind. The winds managed to build new slabs in alpine terrain, Westerly winds would put those slabs on easterly aspects, but expect some isolated westerly cross loading in tighter valleys. It seems treeline has been spared with only isolated new windslabs. Today was another day of sustained warm temperatures which had a settling effect from 2250-2400m. Below 2250m any sunny slope had moist snow by 1200. Expect a new surface crust by tomorrow morning.

Weather Summary

Sunday will be a bit warmer than today. Freezing level will be about 2300m, with 2000m temperatures around +5. Needless to say, but worth reiterating, expect high solar input tomorrow. This will soften the snow before the air warms up. To round out the forecast, expect broken skies, maybe a short lived flurry or two and light winds.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Start your day early and be out of avalanche terrain during the heat of the day.
