Avalanche Advisory
Advisory: Skyline Area Mountains Issued by Brett Kobernik for Friday - December 18, 2015 - 6:52am
bottom line

Weak old snow from November with a large amount of new snow added on top of it along with recent stronger winds has created a CONSIDERABLE avalanche danger in the mid and upper elevation terrain. The old weak snow will continue to make the avalanche conditions quite dangerous through the weekend. Human triggered avalanches are likely. Continue to avoid the steeper terrain in the mid and upper elevation terrain that faces west, north and east.
recent activity

I observed a number of avalanches on Thursday that released naturally early in the morning from a bump in wind speeds and a few inches of new snow. These all broke on weak snow near the ground that fell in November.
