Avalanche Forecast
Regions: Glacier.
Weather Forecast
Thursday expect another 15cm of snow, moderate to strong SW winds and freezing levels rising to 1700m. Overnight and into Friday freezing levels will drop, alpine temps are expected to lower to -8'C, and the snow will taper off. Saturday expect flurries to accumulate to another 7cm, with gusty SW winds at ridgetop.
Snowpack Summary
Up to 20 cm of new snow fell overnight, with temps just below 0 up to 1900m. The new snow is expected to settle rapidly with the mild temps into a slab. The new snow hides variable wind-effected snow in the alpine and soft slab at tree-line and below. Whumphing and cracking on the Jan 4 weak layer, now buried 50-80cm, is still being reported.
Avalanche Summary
A natural avalanche cycle is occurring as I type, with numerous size 2.5-3 avalanches occurring overnight. They occurred from all aspects, and some avalanches triggered deeper slabs at lower elevations on the avalanche fans. Yesterday numerous size 2-3 natural avalanches were triggered by windloading.Â
