Expect rugged and hazardous conditions below treeline if you plan on trying to access elevations where there is enough snow to ski/ride. For those that are determined, be cautious in glaciated terrain where crevasses will be thinly bridged.

Summary

Weather Forecast

Sadly there isn't any significant snow in the forecast. Flurries will bring ~5cm Friday night, and another 5cm on Saturday before cold arctic air moves in with clearing on Sunday. With only 25cm forecast over the next week, expect rugged conditions to continue for a while yet. Check the Mountain Weather Forecast for updates.

Snowpack Summary

The snowpack is slowly building at treeline and above, but diminishes rapidly as you lose elevation, with only 13cm at Rogers Pass (the highest point you can start your tour). 80-110cm of snow can be found at treeline but expect more in alpine lees. Inconsistent but moderate sudden planar test results observed on a crust sitting 30cm above ground.

Avalanche Summary

Several loose and thin slab avalanches up to size 2 were observed from solar aspects on Wednesday. Over a week ago, loose snow avalanches from Macdonald's N face ran more than 100m over bare ground, demonstrating that the valley bottoms are susceptible to overhead hazard even if they are not snowbound.
