Date Issued   Friday, 18 April 2014 10:00 PM      Valid Until    Saturday, 19 April 2014 9:00 PM

A weak freeze is forecast overnight and clear skies are forecast for Saturday.  The snowpack will deteriorate quickly on Saturday, especially on Solar aspects so early starts and early finishes are key.  Pay close attention to temperature and aspect.

Danger Rating: Saturday Alpine Treeline Below Treeline
2 - Moderate Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.
3 - Considerable Dangerous avalanche conditions. Careful snowpack evaluation, cautious route finding and conservative decision making essential.
4 - High Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

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.

Wind Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?

Along ridgelines , ridgecrests and in gullied terrain expect to encounter these problems

Travel and Terrain Advice
  • Avoid freshly wind loaded features.
Loose Wet
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?

Steeper terrain at treeline on all aspects and up to ridgelines on solar aspects.

Travel and Terrain Advice
  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Deep Persistent Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?

This deep instability can become a problem with increased amounts of sun and or rain.  Have in your mind the "what ifs" of a large avalanche.

Travel and Terrain Advice
  • Be aware of thin areas that may propogate to deeper instabilites.
  • Minimize exposure to sun exposed slopes when the solar radiation is strong.
