Avalanche problem #1 :
The storm has continued Saturday all day long to reach 20 to 40 cm of new snow. Extremes westerly winds has transported this new snow to form really thick at the top of alpine and at treeline N, NE, E and SE slopes. Also, north and south aspects will be probably crossloaded. The field team has observed few instability signs below treeline. With a CONSIDERABLE rating, natural avalanches are possible while human triggered avalanches are likely.
With the blizzard conditions at ridgetop this Saturday, our observations in the alpine are limited. 20 to 40 cm of new snow (up to 80cm in leeward slope) covers old hard wind slab below treeline.
Saturday night: 2 to 5 cm of snow, wind at ridgetop of 80 km/h of the NW, temperature in the alpine of -10 C.
Sunday: Chance of snow, wind at ridgetop of 30 km/h from the NW, temperature in the alpine of -16 C.
Monday: No precipitation, wind at ridgetop of 20 km/h from the SW, temperature in the alpine of -13 C.
Tuesday: 5 to 8 cm of snow, wind at ridgetop of 70 km/h from the SW, temperature in the alpine of -6 C.
