  Destructive avalanches may break several feet deep on weak layers that have been further compromised by recent rain and meltwater. Runnels or rills in the snow surface indicate areas that received heavy rain. Recent avalanche activity on adjacent or similar slopes is your most obvious sign of instability. 

  Wet loose avalanches are still possible on very steep slopes that have not yet slid. Any slides in wet snow have the potential to step down to deeper buried weak layers. The simplest way to avoid all of these problems is to stay FAR from steep slopes until temperatures have cooled off and the snowpack refreezes.

  Last weekend's snow and wind grew impressive cornices along alpine ridges. Sustained above-freezing temperatures and rain have weakened these overhanging ledges of snow, and failure is likely. Tumbling chunks of snow can cause large avalanches to fail on buried weak layers. Stay well back from the edge if traveling along ridgelines.
