A storm pushed by a strong westerly flow is moving into the area; this is a good scenario for snow making it's way into inland areas.SUNDAY NIGHT:  Between 10 and 20 cm of snow. Winds moderate to strong, from the southwest.MONDAY: Another 5 to 10 cm new snow means storm snow accumulations as high as 30 cm. Freezing level around 800 m. Winds light to moderate from the west.TUESDAY: Mix of sun and cloud. Dry. Warmer with freezing level near 1000 m. Moderate winds from the west.WEDNESDAY:  Sunny. Dry.

Avalanche Summary

No recent avalanche have been reported from this region.

Snowpack Summary

With a windy and reasonably intense storm arriving Sunday reactive and widespread storm and wind slabs will develop where more than 15 or 20 centimetres accumulates. Incoming snow will cover previously scoured surfaces and old hard windslabs, as well as sun crusts on more solar aspects, and sugary facets pretty much everywhere.February's cold weather weakened the upper- and mid-snowpack. In some sheltered areas, 20-50 cm of previous snow is either faceting or sits on facets (sugary snow), and even possibly surface hoar (feathery crystals).In the south of the region, the lower snowpack is generally strong.

Problems

Storm Slabs

An icon showing Storm Slabs
With the arriving storm expect storm slab and wind slab development. Where more than 15 cm of snow accumulates these slabs will likely become reactive.
Seek out sheltered areas where the snow is unaffected by wind.Stick to non-avalanche terrain or small features with limited consequence.Watch for whumpfing, hollow sounds, shooting cracks or recent avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.
