In sintesi

Most terrain has generally LOW danger.

Though unlikely, it may still be possible to trigger an avalanche failing on a buried persistent weak layer on steep slopes facing NW through E. Likely trigger points include thin, rocky areas, slopes with steep convexities, and areas of more extreme terrain.

It's also still very low tide out there. Beware of rocks, stumps, and deadfall lurking beneath the surface.

    A classic setup of stronger snow over weaker snow has developed on upper elevation, northerly aspects that retained snow from October. This October snow has become loose, weak, and sugary, or as we say, faceted. This faceted snow has formed a persistent weak layer at the base of the snowpack. Time and warmer temperatures have helped heal this buried persistent weak layer, or at least seen it move into a state of dormancy. The odds of triggering an avalanche on this weak layer have grown increasingly unlikely, but human triggered avalanches up to 2' deep are still possible on steep, northerly facing slopes at upper elevations.

Look for increasing clouds today as a weak low pressure system moves inland off the coast of Southern California. Light WNW winds will become more westerly throughout the day and high temps will be in the low 30's. Tuesday will be mostly cloudy with the next disturbance dropping into our area Thursday night into Friday. It doesn't currently appear to be much to get excited about.

Snowpack

It's been more than two weeks since the mountains received any significant snow and overall coverage remains quite thin. Depths across the range average 2'-3' deep above about 9000'. Northerly facing slopes above about 9500' have held snow since October, and this old snow has formed a weak, sugary, faceted layer at the base of the snowpack. Snow from two storm events in December have formed a dense slab over top of this weak, sugary snow. Human triggered avalanches failing on this persistent weak layer are becoming increasingly unlikely, but they may still be possible on steep, northerly facing slopes.
