INCREASED HAZARD. Touchy wind slabs out there. We please ask people to stay out of committing terrain. COVID19 is a serious problem and we don't want to add more work to the health care system.
Summary
Confidence
Weather Forecast
Friday is forecast for another day of strong winds from the SW. Skies will be cloudy with the odd flurry and a temperature of -4c. Freezing level is forecast at 1600m.
Avalanche Summary
One new size 2.5 avalanche was noted on the east face of Mount Murray. It was initiated by a cornice release and the slab stepped down to ground in the upper section.
Snowpack Summary
Big changes in the last 36hrs. We have received about 30cm of recent snow in the last few days that is slabbing up.The winds started on Wednesday and Thursday saw strong westerly winds. The alpine and parts of tree line have new slabs that are skier triggerable up to 50cm deep. With winds increasing on Friday, expect the windslabs to grow more and become more widespread in open terrain. Cornices are growing again, avoid being under them.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Avoid convexities, steep unsupported terrain and rocky outcroppings.
- Be aware of the potential for large avalanches due to the presence of a deep persistent slab.
- Caution around slopes that are exposed to cornices overhead.

Deep Persistent Slabs
The deep persistent layer is still a concern, especially in shallow snowpack areas. A large cornice trigger could also be enough to weak up this layer.
