In sintesi

Cooler temperatures are helping to stabilize the snowpack; however, remain vigilant. The sun's energy, if it comes out, can quickly and unexpectedly increase the danger.

Problemi valanghivi

  • Wind Slabs

    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.

  • Persistent Slabs

    Previously formed slabs now comprise the upper and mid-pack in many locations. Natural and human triggered avalanches are possible.

Weather Forecast

Temperatures will be -5 to -8 with freezing levels 1100 to 1400m next few days. Winds will be light to moderate SW with some strong gusts. 5-10cm Saturday into Sunday evening with continued flurries and mixed clouds into the week. Pray and offer sacrifices to Ullr.

Snowpack Summary

Cooler temperatures are stabilizing the snowpack. Solar BTL locations have a 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

Good visibility Saturday with no new naturals noted. Monday-Thursday's warm temperatures and sun induced afternoon natural avalanche creating numerous loose wet to sz 2 at lower elevations and some size 3 slabs in the alpine.

Confidence

Timing or intensity of solar radiation is uncertain
