40 to 50 cm of recent new snow may become more reactive with extended periods of sun and afternoon warming.
The sun packs a punch this time of year. Reduce your exposure to steep slopes facing the sun during the warmest parts of the day.
40 to 50 cm of recent new snow may become more reactive with extended periods of sun and afternoon warming.
Expect loose snow point releases on steep or rocky solar aspects, especially in the afternoon.
There were no reports of avalanche activity Sunday and Monday.
On Saturday, skier triggered storm an wind slabs were reported up to size 1.5 at and 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.
