Avalanche Forecast
Regions: Little Yoho.
Weather Forecast
The forecast for April 30th and into the first few days of May is for cloudy days with snow flurries at higher elevations and rain showers at lower elevations. Temperatures will be cooler during the day but over night freezes may be fairly minimal due to the cloud cover, except at high elevations. Freezing levels between 2000-2400 m are expected.
Snowpack Summary
5-10cm of new snow in the alpine on April 29th. Crust or moist snow on all solar aspects depending on temperatures. Buried temperature crusts to 2600m on all aspects and to ridge top on solar slopes. Moist snow at lower elevations, with the entire snowpack becoming isothermal near valley bottom.
Avalanche Summary
We have seen regular loose wet and wet slab avalanches up to size 3 running on all aspects in the afternoon and early evening during the warmest times of the day. Cornice failures have also been fairly regular, occasionally triggering slabs on the slopes below.
