Potential for triggering will increase significantly over the week as the temperatures seep into the snowpack. If triggered, it's expected to be very large, running full path.
Weather Forecast
Sunny with cloudy periods. Alpine temperature: Overnight Sunday, Low: -4, High 4C.Ridge wind light with some gusts.Freezing levels will rise as high as 2200 metres; up to 2800 metres on Monday, and forecasted to over 3000m from Tuesday, through the rest of the week.
Snowpack Summary
Moist surface snow treeline and below and the alpine is heavily wind effected. Deep snowpack areas are relatively strong through most of the region. Shallow areas are weak, and will morph quickly to moist 'spring like' slab conditions from the surface down. With the persistent basal weakness, this could fail with the full depth of the snowpack.
Avalanche Summary
Numerous loose wet avalanches on solar aspects at all elevations. These will continue to entrain the surrounding snow and could potentially get very large.
