Lo esencial

Cloudy conditions should limit the amount of afternoon solar related avalanche activity, but watch locally for increasing avalanche danger on solar aspects if the sun pokes out. SH

    There have been many cornice failures over the past week, and in isolated events have been enough load to trigger deeper basal layers.

Weather Forecast

Freezing levels to valley bottom by Friday morning rising to 2000-2200m by the afternoon.  Mainly cloudy with up to 5 cm in alpine regions throughout the day Friday and generally light S winds.

Snowpack Summary

Supportive crusts on solar aspects in morning which are deteriorating by mid day. High elevation north aspects still have dry snow. Mid pack is well settled with no significant shears. The basal facets remain the main weakness in the snowpack, but we expect only large loads or a dramatic rise in temperatures to cause failures on this layer.

Avalanche Summary

Cloud cover and cooler temperatures prevented the typical afternoon solar cycle from occurring, and no new avalanches were reported.
