Dense, very touchy storm slabs developed overnight with the new snow and warm temperatures. More snow is forecasted for the next 24 hours.

Rain to 1900m has created unstable conditions below tree-line. Travel is not recommended.
Weather Forecast
A second pulse from the pineapple express will hit the Rockies tonight and tomorrow, bringing up to 30cm of snow at higher elevations and rain below 1900m. Winds will be moderate to strong from the west. Temperatures will continue to be mild for this time of year (freezing level rising to 1900m), with no cooling overnight.
Snowpack Summary
A warm, windy night brought 15-20cm of dense snow. This has created very touchy storm slabs in the alpine and at tree-line. Below tree-line, there was rain to 1900m, creating unstable surface conditions.
Avalanche Summary
We are currently in a natural avalanche cycle, and will be for the next 24 hours at least. A field team in Yoho remotely triggered a size 2 slab avalanche while moving through moraines above Takakkaw Falls. They noted that conditions were very touchy and retreated. Below tree-line, numerous loose slides to size 1.5 were observed in Yoho.
