Points saillants

With warm temperatures and hot sun, loose wet avalanches will be easier to find than a chocolate egg at a child's Easter egg hunt.

    Rising temperatures and full sun will cause a loose wet avalanche cycle, expect higher reactivity where dry snow is being warmed for the first time.

Confidence

High

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

No new avalanches have been reported.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

Warm daytime temperatures and clear nights have transformed the 40-60 cm of new snow that fell this past week. In many areas, a surface crust will likely exist, and by the heat of the day, the snow will be wet and possibly slushy.

Steep south through west facing slopes may have a thin, breakable crust under the new snow which may allow for better propagation of wet avalanches.

The thick and strong mid-March crust is now expected to be buried by 50-60 cm of mostly settled snow.

Below this, the rest of the snowpack is wet but well settled and strong.

There is little to no snow below 1000 m.

Terrain and Travel Advice

  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
