Weather Forecast
Sunny with cloudy periods for the next few days. No precipitation in the forecast until Friday. Freezing levels will fluctuate with daytime heating rising as high as 1600 m later in the week. Light southerly winds for most of the week.
Avalanche Summary
Reports are beginning to surface of small, loose wet avalanches in steep south facing terrain. A natural cornice failure was observed at 2300m on a north aspect, but did not trigger an avalanche
Snowpack Summary
Recent storm snow is sitting on a variety of surfaces including a 5 cm thick rain crust that exists up to at 2200m. Recent southwest winds have shifted new accumulations into wind slabs in lee terrain. A facet/crust layer buried in mid-March is down approximately 70-130 cm and is still producing hard but sudden results in snowpack tests. This remains a serious concern in the region due to it's potential to produce very large avalanches. Cornices are also a concern these days. A cornice failure may trigger a large destructive avalanche. Solar aspects are now becoming active with daytime warming.
