Kananaskis Country Avalanche Forecast
Apr 7th, 2019 3:00PM
Spring conditions have taken hold. Avalanche hazard will vary from LOW in the cold mornings to possibly HIGH in the afternoon on warm and sunny days. Start early and finish early.
A spring pattern has been established these last few weeks. Cool mornings and warm/hot days are now the norm with afternoon temperatures often well above freezing.If there is a major change in the snowpack, this bulletin will be updated more frequently. Until then, avalanche bulletins will only be updated as needed. Early starts are key at this time of year.
Wet slides either in the form of slabs or loose are occurring most days when the temperature and solar radiation increases. In general we are seeing slides mainly in the size 1 to 2 range, but large avalanches are possible due to the deeper weak layers. Always be thinking about consequence as you travel.
Spring is here it would seem! The snowpack varies in its stability depending on a number of different factors. Day time high, quality of freeze overnight, aspect and influx of new load from snow or rain. In general, as temperatures warm up, stability will decrease. These decreases will be most apparent on solar aspects where the radiation is strong. The timing on this decrease will vary but can be affected by overnight freeze and aspect. Poor freezes mean avalanche danger will increase quickly with warming. Northern aspects are still holding some dry snow at upper elevations but expect a battle up and down from there. The deep persistent weak facets will be with us until the snow is gone. Be sure to asses this layer as you travel. Some good corn is out there if you can get the timing right!! Start early and be home early and avoid the heat of the day.
Deep Persistent Slabs
Loose wet slides may step down to deeper layers and involve the entire snowpack.
Be aware of the potential for wide propagations due to the presence of hard windslabs.Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of thin areas that may propogate to deeper instabilites.
Loose wet slides are occurring in the upper snowpack on warm and sunny days. These may step down to deeper layers
Use extra caution on solar slopes or if the snow is moist or wet.Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Aspects:South East, South, South West, West.
