Points saillants

As you get above the rain crust, start thinking about storm slabs.

Lee areas in the alpine are the most dangerous.

    The more new snow on the crust, the more dangerous this problem will be. Check to see how the new snow is bonding to the old.

Avalanche Summary

A few small wet loose avalanches were reported on Monday.

Snowpack Summary

Around 10 cm of snow sits over a widespread melt–freeze crust. Beneath this crust, the snow remains moist due to the recent warm and wet weather. Lower elevations are rain soaked and likely will develop a crust overnight.

The mid-snowpack is generally well-settled and well-bonded, sitting above a thick melt-freeze crust that makes up most of the lower snowpack.

Snowpack depths at treeline range from 80 to 150 cm and thin rapidly at lower elevations.

See this report for a good idea of conditions.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
