    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.
  • Loose Wet

    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.
