This forecast produced by the Public Safety staff of Kananaskis Country, Government of Alberta. For more information: avalanche.safety@gov.ab.ca phone: 403-678-5508

Date Issued   Wednesday, 23 April 2014 10:00 PM      Valid Until    Thursday, 24 April 2014 9:00 PM

Rapid loading or rapid heating will cause stability to deteriorate quickly.  Pay lots of attention to the aspect you are traveling on.

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.

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

  The basal facets are producing large slab avalanches that are failing on the basal facets.

Travel and Terrain Advice
  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
  • Avoid exposure to solar aspects overhead, large avalanches may reach the end of run out zones.
  • Choose the deepest and strongest snowpack areas on your run.
  • Cornices become weak with daytime heating.
Loose Wet
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?

Loose wet point release avalanches are occurring on solar aspects related to daytime warming.  In some areas these smaller avalanches are triggering slabs on underlying slopes.

Travel and Terrain Advice
  • Minimize exposure to sun exposed slopes when the solar radiation is strong.
