Wind slabs (now buried by up to 10cm of recent snow) are widespread. In steep and unsupported terrain, they could be sensitive to human triggering.
Despite the drop in danger levels, cautious terrain selection is still in order. Wind slabs are highly variable, and could surprise a rider in steep terrain or lee loaded gully.

Recent avalanches have stepped down to this layer triggerring large avalanches.
Monday will be a mix of sun and cloud with light to moderate SW winds at ridgetop. A cool morning will warm to near -7 by early afternoon. Most forecasts indicate that there is no new snow expected, but at least one model indicates occasional light flurries through the day.
Nothing new observed today.
2 to 3cm of new snow overnight, adds to the 5cm that fell yesterday. Alpine areas are significantly affected by wind, with widespread wind slabs present. These are now somewhat disguised by the recent snow. The depth and character of these slabs is highly variable. Dig down and evaluate the recent interface before entering a line. The November crust layer has been active in a few recent avalanches which indicates it's potential if overloaded. This layer is also highly variable in character, and will be on our minds for some time to come.
