Pay attention to signs of instability like cracking and collapsing of snow layers as the storm snow settles and bonds with the old snow surface. Investigate and test the snowpack before committing to any line.
Weather Forecast
A break between storms today with a mix of sun and cloud in the forecast with isolated convective flurries. Temperatures will range from 0 to -9 with a freezing level up to 1100m and 20-50km/hr winds from the west. The next pulse of snow will arrive Thursday and is forecasted to deliver 10-20cm by Friday evening, with another storm arriving Sunday.
Snowpack Summary
30cm in the past 24hrs brings the weekly total to 60cm of storm snow. Moderate to strong winds have redistributed the new snow into wind slab on lee features. Watch for a buried crust up to 2000m on all aspects and on steep solar aspects into the alpine down 30-60cm.
Avalanche Summary
Artillery avalanche control yesterday produced results up to size 3.0.Skier triggered sz 2 wind slab on Monday afternoon occurred on a steep NE aspect, no involvement, read the report here. A sz 2 skier accidental occurred Saturday midday on a westerly aspect on a cross loaded feature. It ran for 350m and injured the skier.

Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
