New snow continues to accumulate over a potentially weak layer.
Dangerous avalanche conditions exist due to heavy snow and rain.
New snow continues to accumulate over a potentially weak layer.
Heavy rainfall has the potential to saturate the upper snowpack, increasing the risk of wet loose avalanches at lower elevations.
No recent avalanche activity has been reported.
However, we anticipate a widespread avalanche cycle to take place Thursday night, into Friday during stormy weather conditions.
New snow continues to accumulate over a variety of wind-affected surfaces, faceted crystals, and surface hoar, all of which could prolong the bonding time between new snow and buried surfaces.
Continued snow or rain and warming temperatures will likely result in an upside-down upper snowpack by the end of the day on Friday.
The mid and lower snowpack is generally settled and well-bonded.
