Summary
Weather Forecast
Periods of snow with accumulation around 16 cm. Alpine temperature -3 C accompanied by westerly winds strong gusting to extreme (50 km/h gusting to 105 km/h). The freezing level of 1700m. Later today cold air should usher in bringing a rapid drop in temperature and an alpine low temp tonight of -17C
Snowpack Summary
20cm+ storm snow then a shift to rain below 2000m with strong S'ly winds will be destabilizing the upper snowpack. Extreme S'ly winds and snowfall will be forming storm slab well down lee slopes. with The mid and lower snowpack is well settled, our persistent weak layers are being tested by this warm storm.
Avalanche Summary
A widespread natural avalanche cycle is occurring now and should continue until temperatures rapidly cool this afternoon. Highway avalanche control is producing moist slides to size 3.5 running to the bottom of the runouts.
Confidence
Problems
Storm Slabs
Warm storm slabs are failing naturally from precipitation and wind overload. These slides are running to valley bottom.
- Avoid avalanche terrain, large avalanches may reach the end of run out zones.
Aspects: All aspects.
Elevations: All elevations.

Loose Wet
Freezing levels are 1900m+ with significant rainfall for lower elevations. Loose wet slides should be expected below treeline.
- Avoid avalanche terrain.
