Natural avalanches are likely.

Avoid exposure to avalanche terrain during periods of high hazard.

Moderate

• We are uncertain due to the timing, track, and intensity of the incoming weather system.
• We are confident the likelihood of avalanches will increase with the forecast weather.

Cornices continued to be controlled this week, with size 1 to 1.5 results. A few wet loose avalanches were reported in the last few days.

We expect avalanche activity to increase with the forecasted weather.

30 to 45 cm of new snow is expected by the end of the forecast period on Tuesday. This new snow overlies a melt-freeze crust, moist snow, or isothermal conditions, depending on aspect and elevation.

The snowpack has undergone multiple warming and cooling cycles, forming a series of crusts with dense, rounded grains in between.

• Watch for fresh storm slabs building throughout the day.
• As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
• Don't let storm day fever lure you into consequential terrain.
