Highlights

Spring conditions. Plan to travel when the snow surface is frozen and strong.

Avalanche problems

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely
    Size
    1–2
    Isolated storm slabs may be found at upper elevations.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    Solar warming can weaken snow surface layers and lead to loose wet avalanches in steep terrain.

  • Wet Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    3–6
    Wet slabs are becoming less likely, but could still occur during warming. Glide slabs may also occur where the whole snowpack is sliding on a smooth ground surface, like rock slabs.

Weather Forecast

A mix of sun and cloud, light winds and mild temperatures are expected over the next few days. A few convective showers are possible. The daytime freezing level stays around 1200 m until Wednesday, when it begins to climb again.

Avalanche Summary

Most operators have shut down for the season. Please continue to share your backcountry observations through the Mountain Information Network.

Snowpack Summary

Storm slabs may be found in the high alpine. At lower elevations, monitor the overnight freeze of the snow surface. If the snow surface does not freeze overnight or if the crust is thin or breakable, daytime heating or rain will weaken the snowpack much more quickly than if there is a well frozen thick crust. Low elevation and thin snowpack areas are isothermal.
