We have had upwards of 35cm of new snow this week with another 10cm forecast. Winds are expected to increase on Friday and bring the hazard to Considerable. Be cautious when approaching tree line and open areas.
Dig down to evaluate the recent HST interface. This layer seems more reactive in the Highwood zone that recieved more snow.
This slab is sitting on the October crust which has facets above it and provides a good sliding surface.
3 new avalanches within the storm interface were observed today in the Highwood Pass region and 1 along the Spray road. As the winds increase on Friday, we will get to the tipping load to trigger avalanches. This photo is in the Dogleg area along the Spray Road that happened sometime on Thursday.
Another 15cm of snow on Wednesday night for an average storm snow of 20-35cm. The height of the snowpack varies from 60-90cm.
The forecasters went into the Pocaterra region at Highwood Pass today. The two layers that we are tracking right now are the storm interface down about 30cm and the October crust down 40-50cm. The recent storm snow is settling and has produced a few new avalanches in the last 48hrs. The October crust is predominant on North and East aspects and not observed on South aspects but is still producing whumphing. As the winds increase on Friday, the rating will become Considerable.
See image Below. Temperatures on Friday will be between -4 and -9c.
