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. Expect a mild freeze on Thursday AM but freezing levels will rise to around 3000m. Expect the same for Friday.

Terrain and Travel Advice

  • Start your day early and be out of avalanche terrain during the heat of the day.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
