Overnight: Freezing level remaining close to 2000 metres with moderate southerly winds and a chance of flurries. Monday: 3-5 cm of new snow with moderate west winds and daytime freezing up to 2000 metres. Tuesday: Mostly cloudy with a chance of broken skies and moderate southwest winds. Expect freezing levels to remain near 2000 metres. Wednesday: Mostly sunny with moderate westerly winds and daytime freezing up to 2400 metres.

Avalanche Summary

Loose wet avalanches up to size 1.5 were reported from the Fernie area on Sunday. These avalanches occurred on steep southeast thru southwest aspects. Expect cornices to continue to be a concern for natural activity. Cornices are large and may be fragile due to the changing temperatures and diurnal freeze/thaw cycle.

Snowpack Summary

A couple of cm of new snow on Sunday morning with a good freeze has resulted in dry snow on northerly aspects above 1800 metres. The near surface crust was reported to have broken down on all but north aspects in the alpine. The snowpack is generally well settled and continues to transition into a spring melt/freeze regime. Below 1300m the snowpack may be moist or wet through its entire thickness. In the alpine cornices continue to grow large and ever more overhanging.
