Freezing levels reach well into the alpine Wednesday and Thursday causing surface snow to slowly deteriorate. A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.

Avalanche Summary

No new avalanches have been reported in this region since Jan 21. Please continue to post your reports and photos to the Mountain Information Network.

Snowpack Summary

10-20 cm of storm snow from the weekend is found in wind-sheltered terrain features. In some areas, new snow sits on top of a thin melt-freeze crust. 50 cm of settling snow sits over a hard crust at higher elevations. Below 700 m surface is a hard crust.

Last week's rain saturated the snowpack and created a well-consolidated lower snowpack.

Terrain and Travel Advice

Be especially cautious as you transition into wind affected terrain.
Back off slopes as the surface becomes moist or wet with rising temperatures.
Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet

Problems

Loose Wet

40 -50 cm of snow sits above a thick crust. With freezing levels well into the alpine, brief periods of direct sun could produce natural avalanches cycle on surface layers.

Aspects: All aspects.

Elevations: Alpine, Treeline.
