Overnight temperatures below freezing combined with clear skies last night have helped the snowpack to cool down. Most surfaces will likely have developed a melt-freeze crust on the surface this morning. As the crust breaks down from warming temperatures, wet loose avalanches will become more likely. High temperatures in the Blues today are forecasted to be in the low to mid-50s.
East-facing slopes will start heating up in the late morning and the sun will work its way onto southerly slopes, then westerly slopes by the late afternoon. Look for clues to wet loose activity such as roller balls or pinwheels, and look for "point releases" out of rocky outcroppings or cliff bands. Plan your travel accordingly to avoid being on or under warming steep slopes in the afternoon. Expect any natural or human-triggered wet loose slides to run easily on the underlying crust.
If you step off your machine or out of your boards and are wading around in wet unconsolidated snow, you've got the right conditions to produce wet loose avalanches. If experiencing this, seek out lower-angle slopes on shadier aspects for the rest of the afternoon. Consider the results of getting caught up in even a small wet loose avalanche if it were to knock you off your feet and carry you over consequential terrain such as cliffs, into dense trees, or into a gully feature.

This D1 wet-loose avalanche was intentionally triggered through a ski cut. the 2-3" of warm snow slid easily on the underlying crust.
