Avalanche Forecast
Regions: Glacier.
Weather Forecast
Unsettled weather is expected through the weekend. Expect mostly cloudy skies with sunny periods and isolated flurries, cool temps of -10 to -20 and gusty westerly winds at ridgetop. The sunny periods are a concern as the new storm snow will become more reactive with the initial hit from the sun.
Snowpack Summary
1-1.4m of storm snow is settling into a cohesive slab over the Feb 10 facet/surface hoar/crust interface. Snowpack tests give spooky results and indicate that the Feb 10 PWL is triggerable with a propensity to propagate. In addition, layers in the top 60cm of the storm slab are reactive and if triggered will likely step down to the Feb 10.
Avalanche Summary
Yesterday 2 size 3's and 7 size 2-2.5 avalanches were observed along the highway. Many running right to avalanche fans. And on Wednesday, a significant event west of the park saw wind blast from a slide from extreme terrain knock down 150 year-old timber. Less cracking and whumphing is being observed while traveling but the layers remain reactive.
