Cold temps should lead to a decrease in avalanche hazard.

Keep in mind that an emergency situation may be amplified by the cold temperatures. Be prepared and watch for frostbite.

Weather Forecast

Partly cloudy skies, light winds and cold temperatures forecasted with daytime high temperatures expected to be around -20C.

Snowpack Summary

Cold temps promoting surface facetting. HST (25-55cm) bonding well to underlying surfaces (facets, surface hoar and wind affected snow depending on location). Wind slabs in the ALP and exposed TL. A well settled mid-pack, except in areas with a shallow snowpack, can be found throughout the forecast region. Variable HS (90-200cm).

Avalanche Summary

No avalanches observed. Poor visibility, unable to see most avalanche paths.
