In sintesi

Wet snow avalanches will be possible on Thursday. The occurance of these avalanches will be related to timing and aspect. Slopes in the direct sun during the warmest time of the day will have the greatest likelihood of avalanching. As the snow becomes wet and slushy to ankle deep or more, wet snow avalanches can happen. Small avalanches on sustained steep slopes and above features like rocks and cliffs can lead to higher consequences of getting caught in an avalanche.

    Monitoring the surface snow is the key to gauging this problem. The deeper the snow becomes wet and slushy, the bigger the avalanches can be. Most wet loose avalanches will be small. At the lower elevations the daytime high temeprature will get into the upper 40's and may lead to avalanches becoming bigger. 

    Avalanches large enough to bury a person are unlikely but remember small avalanches can still be dangerous in steep terrain where long sliding falls or getting pushed into or over rocks can lead to a bad outcome. 

    Use timing, aspect, and terrain choice to minimize risk associated with this problem.

Avalanche Discussion

Be cautious of cornices at ridge tops near and above treeline. The weight of a person can cause cornices to break and can lead to a fall down the slope below. Warming and direct sun can cause cornices to break off naturally. Don't linger underneath cornices.
