    Windslabs are building in isolated below treeline locations. Alpine is experiencing some intense transport as well. Caution on cross loaded gullies and steep lee aspects.

Weather Forecast

No love for the weather gods this Valentines day! They just constantly let me down! Temperatures will be seasonally reasonable, -6 to -7. It's the cold dead heart of the wind making me miserable! Consistent moderate to strong south, sw-ly winds blowing any new snow (5-10cms) into oblivion.

Snowpack Summary

Cooler temperatures are stabilizing the snowpack. Solar BTL locations have a terribly variable un-supportive 10cm crust. Windslab building at BTL locations and intense transport in ALP occurring. Persistent slab TL-ALP in midpack. Weak midpack and basal facets exist. Suspect decomposed surface hoar down 40cm. It's distribution is uncertain.

Avalanche Summary

Poor visibility Sunday. No new natural avalanches reported.
