Triggering storm slabs will be most likely in wind affected terrain.

Use small, low consequence slopes to test the bond of the new snow.

• We have a good understanding of the snowpack structure and confidence in the weather forecast.

No new avalanches were reported on Wednesday.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

10 to 20 cm of recent snow and strong southwest winds have formed storm slabs that will be most reactive in wind affected terrain.

Within the top 100 cm of the snowpack, there may be a few layers of surface hoar, facets, crusts or a combination. These layers appear to vary in their distribution and have not triggered recent avalanches, but they could become reactive in isolated areas as additional snow accumulates above them.

The remainder of the snowpack is well settled and strong.

• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
• Expect slab conditions to change drastically as you move into wind-exposed terrain.
• Use small, low consequence slopes to test the bond of the new snow.
• Even brief periods of direct sun could produce natural avalanches.
