Strong SW winds are creating wind slabs in NW to SE lee aspects. Sensitivity expected to be reactive in the immediate future and may wake deeper, weaker interfaces.
A strong south-west wind is ripping through the ridge tops of the forecast region; scouring and loading features with reckless abandon!
Tailing this is a luscious pacific system set to unload up to 50cm of new snow through the weekend. Stay tuned.

A few large avalanches were observed during last cycle early in December and we suspect it was on this layer. Triggering the windslab problem has potential to release this lower problem layer.
Unsettled weather with moderate to strong SW winds for the next few days. Forecast region is under the influence of a weather system tracking from the Gulf of Alaska. On Friday, a sub tropical 'atmospheric river', arrives with rising temperatures and, at times heavy precip through to Sunday.

Sustained moderate to strong SW ridge-top winds likely creating variable soft and hard slabs in all lee features. There is a mid-pack crust/facet interface distributed through the region. It has shown very little reactivity to this point. A weak basal facet/depth hoar layer exists at the base of the pack.
No new avalanches observed or reported.
