Glacier.

Heads up if the sun comes out today!

Give fresh storm slabs a chance to bond to old layers.

Weather Forecast

Today: A mix of sun and cloud. No precip. Freezing levels at 1300m with alpine high of -5 C. Winds light from the south.

Tonight: Cloudy with clear periods and isolated flurries. Winds light from the south. Freezing level 900m.

Tomorrow: Flurries, 7cm. Freezing levels rising to 1600m. Winds light from the SW gusting to 45 km/h.

Snowpack Summary

20cm new storm snow was accompanied by light to mod S winds and warm temperatures. Rain below 1000m yesterday. New snow overlies a strong midpack, with the exception of the Dec 27th surface hoar/crust down 100cm and the Dec 11th surface hoar down 150cm.

Avalanche Summary

Yesterday's artillery control produced numerous size 2-2.5 avalanches, and a few size 3.5s. A natural cycle was also occurring the past two days from steep alpine terrain, and in some cases running to valley bottom. Skier accidentals this week on MacDonald West Shoulder # 4 (see photo here), Video Peak and Grizzly Colouir (see MIN).

Confidence

Due to the number of field observations

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.
