With continued snow and wind expected throughout the day on Thursday, storm slabs may become more reactive throughout the day.
WEDNESDAY NIGHT - Snow, 5-10 cm / southwest winds, 30-50 km/h / alpine low temperature near -2 / freezing level 1100 m
THURSDAY - Snow, 5-15 cm / southwest winds 30-50 km/h / alpine high temperature near -3 / freezing level 1200 m
FRIDAY - Cloudy with scattered flurries, 5 cm / southwest winds, 10-20 km/h / alpine high temperature near -4 / freezing level 1000 m
SATURDAY - Cloudy with sunny periods and isolated flurries / light southwest winds / alpine high temperature near -5 / freezing level 800 m
New snow and wind will mean that storm slabs are likely forming and chances are good that they will become more reactive throughout the day on Thursday.
5-10 cm of new snow from Wednesday right likely sits on a weak layer of feather surface hoar. Another 5-15 cm is expected throughout the day, bringing total new snow amounts to 10-25 cm. The middle of the snowpack contains a mix of hard crusts and facet/crust layers. Snowpack depths remain very shallow throughout the region with about 75-100 cm at upper treeline elevations. Below treeline terrain is below the threshold for avalanches.
