Points saillants

It's a good time to explore more complex terrain if you start your day early and time your exposure right.

Back off of committing slopes if the upper snowpack is isothermal or slushy.

    A prolonged period with no significant overnight refreeze looks to be established. Wet loose avalanche potential may increase under strong sunshine and high freezing levels.

Moderate

Avalanche Summary

No recent avalanches have been reported.

Looking ahead, rising freezing levels with minimal to no overnight refreeze may increase the likelihood of wet loose avalanches and cornice failures.

With limited observations this time of year, sharing your photos and observations on the Mountain Information Network helps everyone stay informed.

Snowpack Summary

A typical spring diurnal pattern is in effect at upper elevations. Daytime warming melts and softens the upper snowpack, and overnight cooling usually forms a hard crust at higher elevations. Freezing levels are expected to reach 2700 m with very limited cooling and crust recovery overnight. Lower elevations will not refreeze and are experiencing an all-melt, no freeze scenario, and are melting out quickly.

Terrain and Travel Advice

  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
  • Start your day early and be out of avalanche terrain during the heat of the day.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
