    Recent snow and wind have left slabs which could be triggered naturally, or by the weight of a person. These may include wind slabs lee to the SW, and storm slabs on other aspects.

Confidence

Fair - Due to the number of field observations

Weather Forecast

Snowfall should taper to light flurries on Friday and Saturday, before the next storm system arrives on Sunday, bringing light snow. Winds are moderate to strong throughout the period, switching from SW to NW on Saturday, and back to SW on Sunday. The freezing level climbs to near 1500 m ahead of Sunday’s storm but drops with the arrival of precipitation.

Avalanche Summary

Glide slabs have been releasing below treeline. At the time of writing, no avalanches have been reported from Thursday, but there may have been some avalanche activity in response to snow and wind-loading.

Snowpack Summary

New snow and strong SW winds are likely to have built wind slabs on lee features, and storm slabs in more sheltered spots. These overlie a variety of interfaces including older wind slabs, a sun crust, an old rain crust, surface hoar, and/or surface facets. At the base of the snowpack, weak facets may be found. Keep an eye out for cornices that could fail.
