Warming, solar radiation and a buried weak layer are driving the avalanche danger to HIGH.
Check out our latest video conditions update here.
Avalanche activity on this surface hoar/facet/crust has been prevalent this week, including some remote triggering. As the freezing levels rise, expect hazard to increase when the snow is warmed for the first time.
Rising freezing levels and solar radiation will drive a wet loose avalanche problem.
Natural avalanche activity will spike with rain and warming to mountain top on Wednesday.
On Monday, several remotely triggered slabs (from 50 m away) were triggered up to size 2. They ran on the late January surface hoar/facet/crust interface, which shows this layer remains reactive.
Freezing levels rising to the mountain top will likely turn snow surfaces moist at upper elevations and wet below. Below this, 45 cm of dry, settling snow sits above a persistent weak crust/ surface hoar and facet layer. This layer continues to be reactive.
The mid and lower snowpack is well settled.
