Avalanche Forecast
Regions: Glacier.
Weather Forecast
The first day in awhile that you won't be able to track the hourly snowfall on the brim of your sweet trucker hat. Expect cloud with sunny periods, temps from -4 to -10 and light winds from the west. No forecasted snow today. Another pacific storm is brewing off the coast and will push inland on Tuesday evening into Thursday, 40-50cm expected.
Snowpack Summary
Another 22cm brings the weekly snowfall total to 160cm adding to the already healthy sized storm slab. Previous moderate to strong south winds have created pockets of windslab in the alpine. Over a meter and a half of settling snow sits on the Jan 16th surface hoar, which is the uppermost PWL and is still distinct and easy to pick out on pit walls.
Avalanche Summary
Several natural avalanches reported yesterday from backcountry users up to size 2.5 with crowns up to 1.5m deep. Suspect these deep avalanches failed on the Jan 16th surface hoar layer. Artillery avalanche control on Saturday produced numerous avalanches, size 2.0-3.5, with several avalanches dusting the highway.
Confidence
Timing or intensity of solar radiation is uncertain on Monday
