Updated on Monday at 6:25 AM: Forecast snowfall amounts for Monday have increased. New snow and wind will create dangerous conditions, especially around wind-loaded slopes.
A number of buried weak layers remain possible to trigger. These layers appear to be most problematic in upper treeline and alpine elevations, in shallow, variable, rocky start zones.
New snow and ongoing southwest winds are forming reactive storm slabs throughout the day on Monday.
On Friday a natural avalanche cycle up to size 3 took place in the south west corner of the forecast region. These avalanches failed on the late January crust.
If you are out in the backcountry please consider filling out a Mountain Information Network report.
Ongoing snowfall and southwest winds have accumulated around 40 cm of storm snow that is being blown into wind slabs. This all sits on a crust from the warming event on January 25th. New snow likely will not bond well to this crust.
The mid and lower snowpack continues to bond and stabilize. A few concerning weak layers can still be found in the top meter of the snowpack including a surface hoar layer from early January and a crust from late December.
