This is the last Avalanche Bulletin of the season.
Avalanche Danger will be HIGH during times of intense solar radiation, warm temperatures and/or rain.

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. |
Solar aspects are susceptible to increasing avalanche danger each day as solar radiation affect the snowpack. Plan your day to avoid exposure to large sunny slopes in the afternoons. Watch for isothermal conditions at lower elevation on all aspects.
Wind slabs are still found in Alpine areas on lee and cross-loaded features. In most areas these slabs sit on a crust. Take the time to evaluate the bond of the wind slabs to the crusts below.
