Start and end your day early. A few centimeters of new snow Monday will improve ski quality.
Solar warming may result in cornice failure, acting as a large trigger on the slope below. Avoid overhead exposure containing overhanging cornices.
Small avalanches have the potential to step down to this deeper problem layer, made up of buried weaker facets below an crust formed earlier in the season.
This will form on solar aspects, starting around rocks and trees that may contribute to warming the snow around them.
Size 2 and 3 avalanches have been observed consistently all week. It is becoming difficult to determine what is new and old. Some avalanches are being triggered by cornice failures, sun, or loose wet slides that trigger deeper layers. Expect this pattern to continue.
There is 10-30 cm of soft or moist snow overlying a crust on all but due north aspects. 5mm Surface hoar sits on top of this crust in many areas. A 50-100 cm settled mid-pack rests on top of weak facets. The lower snowpack consists of depth hoar and breaking down crusts. Tree line snow depth is 110-170 cm.
Sunday night is expected to be 0 °C, 2000m freezing level, and a weak temperature inversion. Monday's weather is scattered flurries, 5 cm of snow, 1 °C, gusting 45 km/h ridge winds, and 2300m freezing level. Tuesday could bring clouds, flurries, and -5 to -2 °C. Wednesday will be similar.
