Avalanche Summary

No new avalanches were reported on Thursday.

NOTE: Observations in this region are currently very limited.

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 2500 m with very limited cooling and crust recovery overnight. Lower elevations may not refreeze and are experiencing an all-melt, no freeze scenario, and are melting out quickly.

Weather Summary

Friday Night

Clear skies. 10 to 20 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 2500 m.

Saturday

Sunny. 5 to 10 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 2400 m.

Sunday

Sunny. 10 to 20 km/h northwest ridgetop wind. Treeline temperature 9 °C. Freezing level 2500 m.

Monday

Cloudy with flurries, 5 to 15 cm snow (above 1500 m.) 40 to 50 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • 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.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Loose Wet

Strong sunshine and high freezing levels may trigger small wet loose avalanches on steep slopes.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5

Wind Slabs

Forecast 5-15 cm of snow and strong southwest wind on Monday could create wind slabs on lee aspects in the alpine.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
