A rain layer about 12’’ under the snow surface continues to be a problematic weakness in the snowpack. Isolated pockets of wind loaded snow on top of this layer can easily produce avalanches. Avoid steep N-NE-S faces with recent wind loading. Also be aware of slopes with terrain traps below them, steep spots under rocks and areas that look more filled in with snow.
