Around a foot of new snow in the last 24 hours from the last wave of the storm above 9k in upper LCC. Cold temps and low density snow on the top of the pack in most sheltered locations. Minor green housing noticed around mid day on certain elevations on south aspects. A few density changes with in the storm snow although they were not very reactive.

Comments

Surprised to only see a few possible slides today. Looked like some activity around the chokes in Two Trees likely during high PI rates yesterday. The only other slide I saw was while driving down canyon. It was just above the Y in north facing terrain at a relatively low elevation. It looked like a shallow soft slab on possibly a density change within the storm snow. No cracking or whomping noticed on our travels thru mostly south aspects today. Height of snow at 10k on a North aspect was around 115 cm.
