Natural avalanches are likely and human triggered avalanches are very likely.
Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.

- Any travel under High danger should exclusively be in flat or gentle terrain, far away from any overhead hazard.
- Be aware of the potential for large avalanches due to buried surface hoar.
- Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
On Thursday, natural avalanches will be likely and human triggered avalanches will be very likely. Avalanches triggered in the storm snow could step down to persistent weak layers. Large avalanches, bigger than size 3, are expected.
On Wednesday, field teams triggered small avalanches on a steep north aspects below treeline.
On Tuesday, riders were triggering size 1 avalanches down 80 cm on a persistent weak layer MINs and seeing signs of instability MIN.
Storm slabs will build rapidly on Thursday with forecasted extreme winds and snowfall.
The incoming storm will further bury persistent weak layers and load them rapidly.
The Feb 9 surface hoar (SH) is down 80-110 cm and remains reactive in snowpack testing. The Feb 9 SH sits over a crust on solar aspects.
The Jan 26th layer, composed of surface hoar/facets/crust, is buried down 120-140 cm. The largest surface hoar is preserved in sheltered areas below treeline.
- We are confident the likelihood of avalanches will increase with the forecast weather.
