What and where is it: You may find small wind slabs formed from 4.5 inches of snow yesterday and nearly 7 inches of total snow recorded by the summit since Sunday. These are most likely to be found on steep east and south-facing slopes above 3000 feet.
How can you recognize it: Look for pillowy drifts of smooth snow that will appear soft and bright white in contrast to the old, hard snow. As you move through terrain, pay attention to your boot and pole penetration to get a sense of the potential size. Use hand shears and column tests to assess how easily the new snow slides on top of the refrozen layer.
How can you manage it: With the new snow, take time to assess the terrain before committing to steep objectives. If you are traveling through cohesive snow deeper than your boot top, take time to assess the sensitivity before continuing. While traveling on the old, refrozen surface limits your exposure to triggering an avalanche, you incur a different hazard with the potential for long sliding falls.
