Lo esencial

CONSIDERABLE avalanche danger will exist today due to wind slab and storm slab avalanche problems.  Dangerous avalanche conditions are expected.  Human and natural triggered avalanches could occur at all elevations today.

    Wind slab avalanches will be likely today in near and above treeline terrain on NW-N-NE-E-SE aspects.  Wind slabs have continued to grow overnight with additional snow and continued gale force SW winds.  Wind slabs could also exist on different aspects and in below treeline areas as wind transport was expected to be intense overnight.  Wind slab development will begin to decrease today as the snow and winds wind down.

    Look for blowing snow, cornice formation, and wind pillows.  Avoid steep wind loaded terrain and runout zones below large cornices.  Large natural and human triggered avalanches are possible.  Good terrain management skills are essential today.

    Storm slab avalanches will be likely on all aspects in wind protected terrain near and below treeline.  We have received up to 2' of new snow over the last 24 hours.  Storm slab instabilities will remain a concern within the recent storm snow or at the new snow/old snow interface.

    Look for cracking around skis and/or any signs of cohesion of the recent storm snow.  Manage terrain and slope angles to avoid exposure on the way up and down.

Avalanche Discussion

*  Reports area wide came in with natural and human triggered wind slab and storm slab avalanches.  D2 avalanches large enough to bury or injure a rider were reported.

*  Intense snow transport along with heavy snowfall was reported throughout the forecast region.  Wind and snow intensity increased into the afternoon and overnight.
