Up to 30cm of recent heavy snow with winds has activated the problems with continuing natural activity. Give the new snow a couple of days to settle and bond.
Up to 30cm of new heavy snow has built reactive slabs. They vary in depth from 20cm to up 60cm thick depending on loading patterns.
The new snow load initiated a natural cycle on this problem the past couple of days. Give it a few days to settle. Consequences would be severe if initiated.
Activity increases with afternoon warming and less of an overnight freeze. Caution around terrain traps where small slides would have severe consequences.
The next couple of days will be generally sun and cloud, no new snow except for maybe a little on Monday and Tuesday, and rising incrementally freezing levels. A wind event may arrive Monday evening with 70km/hr winds.
Moderate winds, mild temperatures and 30cm of new heavy snow Thursday night created widespread slabs in the alpine and into tree line. It rained at lower elevations making isothermal conditions where enough snow exists. A persistent facet weak layer down 40-70cm exists in some locations.
Saturday's field patrol observed loose wet up to size 2, persistent slabs to size 3 on mainly NE aspects in alpine, and also thin windslabs size 2-2.5 E aspects. Yesterday there was a natural cycle with the recent 30cm storm. Friday's avalanche control on Highway 93 produced several wind slab avalanches up to size 2 and some stepped down.
