Lo esencial

The forecast is calling for light snow.  This should make for great dust on crust conditions (if it materializes).

    Pockets of wind pressed snow and windslabs can be found on lee aspects and cross loaded features at treeline and above.

Weather Forecast

Light accumulations of snow over Sunday night and Monday with light Easterly winds.  Things change on Tuesday when a strong ridge brings clear and warm conditions.  Cool nights will create a spring snowpack with a strong temperature crust in the morning that may breakdown with increasing day time heating and solar radiation.

Snowpack Summary

Pockets of wind pressed and soft wind slabs near ridgelines on Northerly aspects at alpine and treeline elevations. Suncrust on solar aspects. 5-10 cm over a supportive temperature crust can be found on all aspects tree line and above to 2500m. The weak basal facet layer is bridged by a strong mid-pack in most areas at treeline and above.

Avalanche Summary

No new avalanche observations.

Confidence

Due to the number and quality of field observations on Monday
