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

Avalanche Summary

No recent avalanche activity has been reported since the warm, wet storm earlier this week.

If you've been out in the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

Around 5 cm of snow sits over a widespread melt–freeze crust, which varies in thickness and strength with elevation. Beneath this crust, the snow remains moist due to the recent warm and wet weather.

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.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Watch for fresh storm slabs building throughout the day.
  • Keep in mind that the high density of wet avalanches can make them destructive.
