Points saillants

We are into a period of daily melt-freeze cycles. Dry snow still exists on high north aspects and lingering small wind slabs may persist at higher elevations.

    Daily afternoon warming may create wet loose avalanches in steep terrain. We expect these to generally be small and originate from steep rocky terrain that attracts the heat.

Confidence

Avalanche Summary

No new avalanches were observed or reported on Tuesday.

Snowpack Summary

Crusts exists on all aspects except high north-facing terrain. These crusts are breaking down during the daily melt-freeze cycle. On high, north aspects, dry snow can still be found and small pockets of windslab may exist but are isolated at best. The lower snowpack is strong and well settled.

Weather Summary

A ridge of high pressure is over the region bringing mainly clear skies and light winds with a chance of afternoon clouds. We should see decent freezes overnight on Tuesday and Wednesday with progressively higher daytime freezing level elevations each day (~ 2500m on Wednesday and ~2900m on Thursday). Thursday night will be less of a freeze.

Terrain and Travel Advice

  • Start your day early and be out of avalanche terrain during the heat of the day.
