Weather Forecast
Saturday: A mix of sun and cloud. Freezing level around 1700 m. Minimal wind.Sunday: Warm and dry, with increasing cloud and winds increasing from the SW in the afternoon. Freezing level around 1600 m. Monday: Light to moderate precipitation, mostly falling in the early morning. Moderate SW winds. Freezing level around 1500 m.
Avalanche Summary
Recent observations include cornice falls (size 1-2) and glide slab releases to size 3.5. Loose moist avalanches were observed during warm sunny weather earlier in the week.
Snowpack Summary
A generally strong and deep spring snowpack exists. At this time of year, snowpack stability tends to decrease during times of warming (e.g. on slopes receiving sunshine, during rainfall, in the afternoon and at low elevations). A crust layer from late March, buried within the upper 2 m of the snowpack, remains a lingering concern. A melt-freeze crust can be found on all aspects below about 2200 m. On high north aspects, dry snow may still be found. Conditions may be quite icy in the morning, so travel with care. Large cornices threaten slopes and glide slab releases are a possibility, especially in steep rocky terrain.
