Observations from Monday Apr 5. Woke up to 30-40cm of new snow, higher in wind-loaded areas. Another 10 throughout the day. Remote and direct triggering of small avis, even in mellow and treed terrain. The new storm snow was sliding right down to the sun/melt-freeze crust. Super touchy and highly reactive, very spooky especially with the poor visibility.
