Waterton Lakes

Windslabs are likely to form as the winds increase from Monday onwards, these may be easily triggered as they form on top of a crust. Lots of exposed hazards still exist below treeline.

Numerous dry loose avalanches up to size 2 observed from steep terrain on Sunday.

10 - 15 cm of new snow being re-distributed by moderate to strong winds into windslabs. This overlies a melt freeze crust complex in the alpine and at treeline. Due to previous warm temps and rain, there is very little snow on the ground below 1800 m.

Mon

Partly cloudy with isolated flurries, winds increasing to strong SW. Alpine high of - 10°C

10 - 15 cm of new snow through the day with strong to extreme SW winds. Alpine high of - 4°C

Wed

Light winds with another 10 - 15 cm of snow possible. Temperature dropping over the day to - 25°C
