Warm temperatures and sunshine are expected to increase natural and human triggered avalanche activity.
Avoid exposure to sunny slopes especially as things heat up in the afternoon.

- Avoid exposure to overhead hazards when solar radiation is strong.
- Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
Human triggering continues on the late Jan surface hoar. Over the past few days field teams have been able to trigger several size 1 slab avalanches at and below treeline.
Regionally there have been numerous natural, skier and remotely triggered avalanches also failing on the surface hoar layer.
Forecast significant warming will turn the snow surface heavy and wet increasing slab cohesion. Roughly 30cm beneath the surface is the late Jan weak layer of surface hoar, facets and a crust. This layer is found on all aspects and elevations with largest surface hoar (up to 40mm) in sheltered areas below treeline. The crust is firmer on solar aspects.
The mid and lower snowpack is generally well settled and strong.
- We are uncertain about how persistent slabs will react to the forecast weather.
