As the new snow falls remember buried wind slabs are still able to be triggered.
Watch for dry loose avalanches running far and fast on the crust.

Avalanche Summary
A few large (size 2) wind slab avalanches were triggered with explosives in the south on Monday.
A rider accidentally triggered a small wind slab avalanche below treeline near Window Mountain on Sunday. The wind slab had formed further downslope than normal.
On Saturday explosive triggered wind slab avalanches up to size 3, failing on the crust layer, were reported in the south.
Snowpack Summary
An upslope storm (coming from the east) could see 10 to 20 cm of light, dry snow near the Continental Divide on Tuesday.
Previous moderate to strong southwest wind developed wind slabs at all elevations. In sheltered spots, expect 20 to 40 cm over the crust.
Below this crust, the shallow faceted snowpack is generally well consolidated. There are two crust layers, one in the midpack and another near the base of the snowpack, that have been unreactive.

Terrain and Travel Advice
- Wind slabs may be poorly bonded to the underlying crust.
- Loose avalanches may start small but they can grow and push you into dangerous terrain.
Problems
Wind Slabs
Old wind slabs will be buried by new snow. They may form further down the slope than normal, even halfway down.
