The most likely place to trigger a large, deeply breaking avalanche is on a northerly slope that had thin coverage before our last storm. Avoid steep slopes with a thin and variable snowpack less than about four feet deep.
On southerly slopes, monitor melt-freeze crusts. Once these crusts melt, wet avalanches are more likely. Long-running wet avalanches can trigger deeper, more dangerous slab avalanches.
