Avalanche Summary

A widespread natural avalanche cycle occurred during the peak of warming on Monday night. Reports suggest numerous avalanches sized 1 to 2.5.

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

Snowpack Summary

A widespread surface crust has formed in the wake of the recent wet, warm storm. In high alpine terrain small amounts of dry snow overly the crust. Any previous layers of concern deeper in the snowpack should now be bridged by the crust.

Weather Summary

Tuesday Night

Cloudy with 2 to 5 cm of snow at higher elevations, southwest alpine winds 30 to 50 km/h, treeline temperature -1 °C, freezing levels around 1500 m.

Wednesday

Partly cloudy with trace precipitation, west alpine winds 10 to 30 km/h, treeline temperature -3 °C, freezing levels around 1100 m.

Thursday

Cloudy with up to 10 cm of snow, south alpine winds 20 to 40 km/h, treeline temperature -4 °C.

Friday

Mix of sun and cloud with trace precipitation, northwest alpine winds 20 to 40 km/h, treeline temperature -6 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Avoid areas where the snow feels stiff and/or slabby.

Avalanche Problems

Storm Slabs

In any alpine areas where a surface crust is not present, reactive storm and wind slabs may exist.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
