Avalanche Forecast

Moderate

Over the warm weekend, wet loose and slab avalanches up to size 2 were observed. These type of avalanches have become unlikely as surfaces refreeze.

Looking forward, wind slab avalanches become increasingly likely as new snow arrives.

5 to 15 cm of new snow sits on a widespread surface crust. Below, the upper snowpack is wet.

A number of decomposing crusts may be found in the mid snowpack. The most prominent was buried in late December and is still producing snowpack test results. The remainder of the snowpack is dense and well-bonded.

• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Closely monitor how the new snow is bonding to the crust.
