Cooling temperatures will reduce the likelihood of triggering this problem. Shallow areas are likely trigger spots.
Weather Forecast
Up to 20 cm of snow expected with cool temperatures and moderate SW winds. Dramatic change on Thursday with rising freezing levels and intense solar radiation.
Snowpack Summary
The freezing level is dropping BTL (1200 m) developing a strengthening melt freeze crust at tree-line and above. Expecting up to 10 cm of snow by Tuesday afternoon. Isothermal continuing conditions below tree-line (BLT). The deep persistent slab problem still the biggest concern on North alpine aspects. BTL becoming below threshold in most areas.
Avalanche Summary
No recent reports or observations today (no avalanche patrol). Point releases and wet slab avalanches have been observed to size 3 running at all elevations primarily on solar aspects. Fewer slides are occurring on northerly terrain. Ice climbs are cracking and collapsing because of the warm temps.
