Watch for recent snow to become increasingly reactive with solar input on Monday.
Rapid settlement due to solar input may cause storm slabs to become increasingly reactive on Monday. Storm slabs exist on all aspects but may be most likely triggered in wind-loaded features.
Expect loose snow point releases on steep or rocky solar aspects, especially in the afternoon.
A natural avalanche cycle was observed up to size 2 through the recent stormy period. On Saturday, skier controlled storm slabs up to size 1.5 were reported below treeline.
Many areas have received 20-50 cm of localized convective snowfall over the weekend, bringing weekly storm totals up to 60 to 100+ cm. The recent snow sits over a crust on all but high north aspects. At upper elevations recent snow has been redistributed by wind.
Below the crust, the snowpack is generally well consolidated. A facet/crust layer in the mid snowpack was put to the test by the significant new snow load and it does not appear to present an avalanche problem at this time.
Below treeline areas have now received enough snow to produce avalanches. Watch for "early season" type hazards such as shallowly buried stumps, rocks and creeks.
