MODERATE avalanche danger continues above treeline and near treeline due to hard wind slabs. Areas of unstable snow are isolated, but the consequences of becoming caught in an avalanche are elevated due to the specifics of the current avalanche problem. LOW avalanche danger exists in wind protected areas below treeline.

MODERATE avalanche danger continues for above treeline and near treeline terrain due to wind slabs formed yesterday from deposits of wind drifted snow. Significant uncertainty exists for near treeline terrain where a wind slab avalanche yesterday was observed to have unusual characteristics. Below treeline, LOW avalanche danger continues.

MODERATE avalanche danger will exist in near and above treeline terrain today due to the presence of both new and old wind slabs. Human-triggered avalanches remain possible on steep slopes where slabs of wind drifted snow have formed. Avalanche activity is unlikely in sheltered, below treeline terrain (LOW avalanche danger).

CONSIDERABLE avalanche danger exists above treeline and near treeline where wind drifted snow has formed into wind slabs. MODERATE avalanche danger exists below treeline due to the possibility of storm slabs and loose dry avalanches.

Avalanche danger is increasing today. CONSIDERABLE avalanche danger is expected to develop this afternoon in above treeline and near treeline areas due to wind drifted snow forming into wind slabs. MODERATE avalanche danger is expected this afternoon below treeline due to the possibility of new snow forming into storm slabs.

MODERATE avalanche danger exists at all elevations. Wind drifted new snow over the highest elevations has created the potential for wind slab avalanches. Rain on snow has created the potential for loose wet avalanches.

MODERATE avalanche danger will exist due to a combination of wind slab and storm slab avalanche problems.  Unusual storm slab conditions continue with buried surface hoar beneath the recent storm snow.  Human triggered avalanches are possible in specific areas today.

MODERATE avalanche danger will exist today in near and above treeline areas due to lingering wind slabsMODERATE avalanche danger will also exist in below treeline areas due to possible storm slabs.  Uncertainty exists about storm slabs and the potential for buried surface hoar.

Significant wind and new heavy snow during the storm have left large unstable slabs of drifted snow (wind slabs) on exposed near and above treeline slopes. In these areas, CONSIDERABLE avalanche danger exists and human-triggered avalanches are likely. In more sheltered below treeline areas, new heavy snow on top of older, lighter, weaker snow means MODERATE avalanche danger due to the possibility of storm slab avalanches.

An increase to HIGH avalanche danger is expected today in near treeline and above treeline areas due to new snow and wind drifted snow creating wind slabs and the potential for large avalanches. CONSIDERABLE avalanche danger is expected below treeline due to high intensity snowfall creating storm slabs. Travel in near treeline and above treeline avalanche terrain is not recommended. Travel in below treeline avalanche terrain will become increasingly dangerous as the day progresses. Lighting strikes are possible this afternoon.

CONSIDERABLE avalanche danger for today in above treeline and near treeline areas due to a wind slab avalanche problem from increasing amounts of pre-storm blowing and drifting snow. Areas of MODERATE avalanche danger may exist as wind slabs form in wind exposed areas below treeline due to the strength of the winds. Numerous wind slab avalanches occurred yesterday and the avalanche problem will become more widespread today.
