Choose conservative, low consequence terrain and give the storm snow time to settle
Rider triggering of avalanches is likely
Weak layers from January and February persist within the upper 100 cm of snow. Rider triggering of these layers is still possible.
Storm slabs will remain rider triggerable. Assess new snow amounts, the more you find the larger and more sensitive slabs will be.
On Saturday, A few small avalanches were triggered at treeline. At least one of these avalanches ran on the mid February layer.
We suspect that a natural avalanche cycle occurred on Sunday but as of the time of publishing we have not received any reports.
New snowfall amounts in the region are variable, By Monday morning 30 to 60 cm may have fallen with strong southwest winds, forming deeper deposits on north and east aspects. This new snow will overlie a crust on all aspects and elevations except north facing slopes above 1600 m. Surface hoar could also be found under this new snow on sheltered features.
A weak layer, composed of facets, surface hoar, or a crust, is found 40 to 100 cm deep from mid-February. Another persistent weak layer, buried in late January, lies just below this layer. This layer is surface hoar, facets, or a crust, depending on the aspect.
The remaining snowpack is well-settled and strong.
