Avalanche Forecast

Moderate

• We are uncertain about forecast precipitation amounts.
• We are uncertain due to variable freezing levels.

No recent avalanches have been reported, but incoming precipitation from Tuesday’s storm is expected to significantly increase the likelihood of avalanche activity.

No recent avalanches have been reported. If you are heading into the backcountry, consider sharing your observations and posting a MIN.

20 to 30 cm of new snow is expected to accumulate at upper elevations by the end of Tuesday, accompanied by strong southerly winds. The snow may switch to rain below 1400 m by the late afternoon.

The new snow will be falling on 5 to 15 cm of recent snow that is covering a widespread, thick and hard crust that is present right to mountaintops.

The snowpack below the crust is strong and bonded with no layers of concern.
There is little to no snow below 1000 m.

• Storm slab size and sensitivity to triggering will likely increase through the day.
• As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
• Be alert to conditions that change with elevation, aspect, and exposure to wind.
