Points saillants

Triggering wet snow avalanches will be possible at all elevations, especially on steep slopes in the direct sun. Most avalanches will be small, but smal avalanches can have consequences in steep terrain. Avalanches have the potential to increase in size as wet slushy snow makes its way deeper into the pack and/or the terrain is bigger. If you begin sinking into wet slushy snow, consider moving to more shaded slopes or to lower angle terrain.

    Use timing to your advantage. We all want the surface to soften up for good riding, but be aware when the signs of wet snow avalanches present themselves. Look for clues like the snow becoming wet and slushy deeper into the upper pack, rollerballs, and pinwheels as signs that these avalanches can happen. Most wet loose avalanches will be small, however be cautious in steep and committing terrain. Small wet snow avalanches can cause you to loose your footing on steep slopes and send you tumbling into whatever is below. If the surface snow becomes wet and slushy to boot top depth or more, loose wet avalanches will gain size and pack more of a punch.  I can envision some pieces of terrain in the forecast zone, where large avalanches may occur; such as big open alpine faces that funnel into a constriction. 

    On Wednesday, I did not observe any active wet loose avalanches happening but I did see the debris from  quite a few previous slides on steep alpine slopes.

    Cornices are not everywhere but you can definitely find them on some ridgetops. Cornices can weaken during warm days especially with direct sun. These are not the days to linger under cornices. If you must travel under a cornice, keep moving and minimize your exposure. Also be cautious when approaching ridge tops especially if you can't see over the other side. Avoid walking out onto a cornice. They can break under the weight of a person leding to a fall onto the slope below.
