Northwest winds are expected to switch to southwest. Watch for fresh and reactive slabs forming on north and east facing slopes.
The lower snowpack remains concerning - best managed by sticking to conservative terrain and minimizing exposure to overhead hazard.
Northwest winds are expected to switch to southwest. Watch for fresh and reactive slabs forming on north and east facing slopes.
Recent storm snow sits over a heavily faceted layer from the prolonged cold period. Until temperatures warm, the bond between these layers is expected to remain weak.
The field team observed several natural wind slab avalanches above Fraser Chutes on Thursday to size 2.5. Read the full report here.
Several avalanches, including a size 2.5 were reported in this MIN from the Tally Ho area, likely triggered last week.
5 cm of new snow adds to 40-65 cm of heavily wind-affected snow. The primary concern remains the 70-100 cm of weak facets that make up the lower snowpack.
Snowpack depths vary widely due to wind, but average around 150 cm across the region.
