Avalanche Forecast
Regions: Little Yoho.
Weather Forecast
Temperatures have been slightly inverted with better freezes at valley bottom, but temperatures will stay above freezing in the alpine Friday evening. Saturday will see solar heating progress quickly with clear skies until midday when winds pick up and bring cloud later in the day. Sunday morning may bring rain below 2000m turning to snow by noon
Snowpack Summary
Crust or moist snow on all solar aspects depending on temperatures. Buried temperature crusts to 2000m on all aspects and to ridge top on solar slopes, including the Mar 15 crust down 40-70 cm in the alpine. Moist snow at lower elevations, with the entire snowpack becoming moist below treeline in the afternoons.
Avalanche Summary
Ongoing wet snow avalanches typical for this time of year are occurring with daytime heating. Both loose snow and wet slabs are common with slabs occasionally stepping down to mid-pack and basal layers. These vary by aspect and elevation but can travel far as they entrain isothermal snow. Many events have reached full path over the last two days.
