Date Issued   Sunday, 15 January 2012 5:52 PM      Valid Until    Monday, 16 January 2012 4:00 PM

Snowfall amounts are tricky to predict at present. If it's snowing heavily, bump up the danger ratings in your area.

Danger Rating: Monday Alpine Treeline Below Treeline
3 - Considerable Dangerous avalanche conditions. Careful snowpack evaluation, cautious route finding and conservative decision making essential.
2 - Moderate Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.

Low Moderate Considerable High Extreme

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

Natural and human-triggered avalanches unlikely.

Small avalanches in isolated areas or extreme terrain.

Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.

Natural avalanches unlikely; human-triggered avalanches possible.

Small avalanches in specific areas; or large avalanches in isolated areas.

Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.

Natural avalanches possible; human-triggered avalanches likely.

Small avalanches in many areas; or large avalanches in specific areas; or very large avalanches in isolated areas.

Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

Natural avalanches likely; human-triggered avalanches very likely.

Large avalanches in many areas; or very large avalanches in specific areas.

Avoid all avalanche terrain.

Natural and human-triggered avalanches certain.

Large to very large avalanches in many areas.

Loose Dry
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?
Loose dry snow will sluff easily in steep terrain. This could knock you off your feet and/or carry you into a terrain trap.
Travel and Terrain Advice
  • Avoid freshly wind loaded features.
  • Be aware of thin areas that may propogate to deeper instabilites.
  • Give cornices a wide berth when travelling on or below ridges.
  • On steep slopes, pull over periodically or cut into a new line to manage sluffing.
Wind Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?
Winds are forecast to pick up again. With so much dry snow available for transport, wind slabs may develop surprisingly quickly. Cornices may also be fragile.
Travel and Terrain Advice
  • Avoid freshly wind loaded features.
  • Be aware of thin areas that may propogate to deeper instabilites.
  • Give cornices a wide berth when travelling on or below ridges.
  • On steep slopes, pull over periodically or cut into a new line to manage sluffing.
Storm Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?
Loose dry snow that fell on Sunday has been shedding off very steep terrain, but accumulating on slightly lower angled slopes. Where it's built up, you could trigger a slab with enough mass to bury a person.
Travel and Terrain Advice
  • Avoid freshly wind loaded features.
  • Be aware of thin areas that may propogate to deeper instabilites.
  • Give cornices a wide berth when travelling on or below ridges.
  • On steep slopes, pull over periodically or cut into a new line to manage sluffing.
