In sintesi

It's spring skiing out there folks!

Keep an eye on surface conditions, as the snow becomes wet and heavy - avalanches are more likely.

    Loose wet avalanches are most likely on steep, south facing slopes in the afternoon - especially near rocks where warming will be most intense.

Confidence

Moderate

Avalanche Summary

Loose wet avalanches were reported on Saturday from steep sun affected slopes. Recent cornice failures were also expected. We expect this activity to continue while temperatures remain warm, with strong sunshine.

If you are headed into the backcountry please consider submitting a MIN report.

Snowpack Summary

Strong sunshine and warm temperatures are expected to break down the surface crust - or moisten surface snow at low elevations, and on steep sun affected slopes into the alpine. Snow on north facing alpine slopes will likely remain dry.

The mid and lower snowpack are generally well-settled. There is uncertainty over whether buried weak layers could react to the warming, and produce large avalanches, including the layer of surface hoar, crust and facets from early December buried 80-150 cm deep. Currently its considered unlikely.

Terrain and Travel Advice

  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
