Tricky conditions continue. Cooler temperatures are on the way, but it will take some time for the snowpack to become less reactive. Solar input will augment the snowpack problems. SH
Summary
Weather Forecast
Cooler temperatures are finally arriving for Sunday with -6C at valley bottom and -10C or cooler in the alpine. Light gusting moderate N-NW winds and a mix of sun and cloud. Seasonal temperatures will persist for the next few days.
Snowpack Summary
60-80 cm settled storm snow at treeline and above overlies a generally settled snowpack. Some snow pits have found facets at this interface. Recent wind slabs have formed on many different aspects at higher elevations. Isothermal snow exists below 2000m. Cooler temperatures Sunday will help overnight crust formation.
Avalanche Summary
Limited observations today in Little Yoho but a natural cycle occurred East of the Divide in Banff/Yoho/Kootenay Parks.These were mainly triggered by recent loading by N winds and sun. Click here for photos of these events. As well, a few skier triggered slides were reported over the last 2 days with limited involvement in the same region.
