The current storm looks to be bringing more of the promised wind than snow: continue to monitor slab development. While we have dropped the persistent slab as an avalanche problem, the Dec 2 FC/CR has not gone away: keep it in mind especially in KNP
As you approach treeline, expect to encounter slab development. Take the time to investigate what the recent snow is sitting on and how it is bonding.
The current storm is expected to bring 5 to 10 cm through Sunday morning. West winds in the moderate to strong range are expected in the alpine with temperatures reaching around -5C at treeline and -12C in the alpine Saturday afternoon. By midday Sunday, winds should diminish and clearing can be expected with some further warming.
Moderate winds continue to redistribute the 10 to 30cm that has accumulated over the Jan 30 crust, surface hoar and wind effect. Hard slabs can be found in alpine. While slab development at treeline is only starting yet these are more likely to overlay a sun crust or surface hoar. Shallow snowpack areas remain weak and faceted.
Both of the ski hills have reported working with stubborn hard slabs in the alpine over the last couple of days. A sz 1.5 skier accidental was reported yesterday in the alpine of one of the Healy Creek paths, and another, right at treeline in one of the "Simpson " road paths in KNP: sz 1.
