In sintesi

Avoid steep sun-exposed slopes during the heat of the day. Don't let your guard down with warm temperatures and sunny skies.

    Treeline and above on northerly aspects will have small storm slabs (in some places sitting on a crust). Storm slabs in the alpine will be possibly more reactive than shown here, especially on northerly aspects.

    Just because it's t-shirt weather and a holiday Monday doesn't mean you can get complacent: Avoid steep sun-exposed slopes during the heat of the day.

Confidence

Moderate - Timing or intensity of solar radiation is uncertain

Avalanche Summary

No new observed.

Snowpack Summary

The snow from late last week (15-25cm) has consolidated well at treeline and below. This makes 50-70 cm of cumulative storm snow which is bonding well to a knife hard crust buried Feb 3rd. In the alpine, where all of the precipitation has fallen as snow, the storm slabs have taken longer to settle out and still are a concern: Dig down to test the bond of the more recent snow layers. The mid and lower snowpack are settled and well bonded with the average snowpack depth at treeline 250-300 cm.
