Lo esencial

Snowfalls and strong winds on the Divide are forecasted to continue for the 24 hours. Widespread natural activity is expected in those areas. This is a good time to pull back the reins until conditions improve.

    Moderate winds this week have also created thin, but stiffer wind slab conditions 25-35 cm deep on ridgetop lee terrain. These have been seen to step down to the Valentine layer and are now buried by further snowfalls.

    Snow depths over the Valentines surface hoar and sun crust on steep solar aspects range from 20cm E of the Divide, to 50+cm at Sunshine and Yoho. Continuing snowfalls and strog winds will increase natural activity on this layer.

    Recent trips east of the Divide have found a shallow, weak snowpack. Tests done showed sudden collapse results on the basal facets. It is still possible to trigger the entire slope from shallow, thinly covered areas.
