Weather Forecast
Overcast skies and flurries are expected to bring light snow accumulations onto the Eastern slopes in the next 24 hours. Winds will be light to moderate from the Northeast and a clearing trend will begin later in the day. Monday will see slightly warmer temperatures and scattered clouds with no precipitation to speak of.
Snowpack Summary
Spring conditions are mostly solid with up to 15cm of snow on the crust layer. In the alpine, wind slabs exist on lee aspects near ridge tops. Sun crusts are well developed on steep, solar aspects. Overcast skies and cooler temperatures have kept the crusts intact even at lower elevations.Â
Avalanche Summary
One avalanche was reported yesterday above the icefalls on the Athabasca glacier which originated from steep, cross loaded gullies in the high alpine. Cooler temperatures and no solar radiation due to cloud cover has reduced natural activity in the last few days.
