Avalanche Forecast
Regions: Glacier.
Weather Forecast
A mild inversion will settle in at higher elevations today, accompanied by clear skies and light winds, with a high of -8 in the alpine. Clouds will start to roll in this afternoon, flurries overnight and up to 10cm of new snow for Friday. Saturday may give us another 5cm, before the Arctic High-Pressure moves back South over Rogers Pass.
Snowpack Summary
A dusting of new snow covers old hard wind slabs, and scoured surfaces in the ALP and exposed areas of TL. Cold temperatures continue to promote near surface facetting at all elevations; deteriorating the bonds of the upper snowpack. Wind slabs were most active on solar asp, where crusts are buried. The Jan 17 SH is down 50-70cm at TL and below.
Avalanche Summary
Yesterday we observed two small sz 1.5 wind slabs on north aspects in "extreme terrain", in the alpine. On Saturday there was a natural cycle triggered by strong N-NE winds. Since the weekend we have only seen sporadic small wind slabs up to size 1.5 in the alpine. There have been no reports of any new avalanches on the Jan17th PWL in over a week.
