Lo esencial

Avalanche danger will rise with daytime warming and strong solar radiation.

Allow the new snow time to stabilize before committing to large, consequential terrain.

Problemas de aludes

    Recent snowfall has likely formed storm slabs at higher elevations, where deeper accumulations of new snow exist. Slabs may be particularly reactive in areas where they overlay a firm crust.

  • Loose Wet

    Wet loose avalanche activity is likely on steep slopes exposed to direct sun.

Snowpack Summary

Recent snow at treeline and above has buried a mixture of moist snow surfaces and firm crusts. Lower elevations have seen a mix of rain and snow falling onto an already moist or isothermal snowpack.

A weak layer of facets above a hard crust may persist 50 to 70 cm deep. This layer hasn't produced avalanches in over a week.

Facets exist at the base of the snowpack in shallow areas.

Confidence

Low

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanche activity has been reported since Monday, when warm temperatures and sun triggered wet loose avalanches.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Investigate the bond of the recent snow before committing to your line.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
