Low - Wind effect is extremely variable
Friday and Saturday look quite convective which means that periods of locally intense snow flurries are possible. The freezing level starts to creep up Saturday as warm air invades from the south. THURSDAY NIGHT: Freezing level at valley bottom, moderate to strong west wind, 2 to 5 cm of snow.FRIDAY: Broken cloud cover, freezing level rising to 1000 m, moderate to strong south/southwest wind, trace of snow.SATURDAY: Broken cloud cover, freezing level rising to 1500 m, moderate to strong south/southwest wind, 1 to 5 cm of snow. SUNDAY: Broken cloud cover, moderate to strong south/southwest wind, freezing level approaching 2000 m, a few mm of precipitation possible.
Few observers in the field this week but reports are consistent with a natural avalanche cycle of storm and wind slabs up to size 2.
20 to 45 cm of slightly upside down storm snow has accumulated since Monday. This new snow rests on previously wind hammered snow, sun crusts (on solar aspects) and sugary facets. February's cold weather weakened the upper and mid-snowpack. In some sheltered areas, 20 to 50 cm of the snowpack was faceting, or sits on facets (sugary snow),In the south of the region, the lower snowpack is generally strong.
