Points saillants

Keep your heads up folks. The weak snow pack and wind slabs will continue to dominate the forecast for the rest of the year.

    Check for freshly loaded spots where a pocket of this instability would exist. Ice climbers, be cautious of cross-loaded gullies and terrain traps

  • Deep Persistent Slabs

    Triggering this layer could have severe consequences. Shallow locations are likely trigger spots and, everywhere should be considered shallow right now.

Weather Forecast

Overnight temperatures are expecting to raise closer to zero through the forecast area. Light snow will continue overnight and through the day. 

Snowpack Summary

Light precipitation over the last few days was not enough to alter the snowpack. It remains shallow and unsupportive. Wind slabs of various thicknesses continue to form in lee locations and there is a variably distributed deep persistent slab overlying weak basal layers of depth hoar, crusts, and facets.

Avalanche Summary

No highway patrol today. No new activity reported in the last 24 hrs.
