In sintesi

The avalanche danger should remain LOW today unless more warming occurs than forecasted. In that case, loose wet avalanche problems could develop.

    Increasing cloud cover and winds should help limit the amount of warming that occurs today. This limited warming combined with minimal recent snow and a strong overnight refreeze should prevent widespread significant loose wet avalanche activity. If any loose wet instabilities do form, they should remain small in most places. However, there is a chance that some could have consequences in areas with terrain traps. If the cloud cover takes longer to develop or temperatures climb higher than forecasted, loose wet instabilities could become larger and more widespread. 

    Monitor conditions while traveling in the backcountry. If the snow starts to warm up, step off your gear or your sled and see how deep the wet snow is. Once it gets deeper than your ankles it is a good time to move to a colder aspect.

Avalanche Discussion

* Yesterday observations from Elephants Back, Tamarack Peak, and Brockway Summit showed shallow new snow (1-4 inches) resting on a melt-freeze crust. At the lower elevations, this crust was breakable and at upper elevations, this crust was firmer.

* Despite some windows of sunshine no wet snow instabilities were reported. 

* No signs of significant wind slab instability were reported.
