Warm spell is over but the aftermath may persist for the next few days despite cooler temperatures and minimal precipitation.
Cornices are awake! These features are extremely large, dense and heavy and will likely trigger the deeper instability on the slope below. If you must travel near or below cornices, use good travel techniques and group management to reduce exposure.
Rapidly rising temperatures and strong solar radiation has made this a variable but significant problem at all elevations and aspects during the warm spell of the last few days, this problem will dissipate as the cold front arrives on Sunday.
Forecasters are noting an increase in activity; seeing many larger slides, stepping down to ground or ice. Shallow snowpack areas and solar aspects have increased potential for human triggered and natural avalanches stepping to deeper layers.
High pressure continues over Northern BC and Alberta, rapidly establishing spring conditions in the region. Positive daytime temperatures, light winds, strong solar and rising freezing level to as high as 3000m can be expected daily and for the near future.
Spring has Sprung! Expect a crust on solar aspects as the warm spell is coming to an end. It may take few days of cold temperature to dry all of the upper snowpack.
Loose wet and wet slabs to ground avalanche activity observed on all aspects up to size 3 throughout the region. Icefalls, seracs and cornices continue to fail and trigger deeper instabilities.
