Upper elevation winds are fairly light again this morning, but Wednesday's wind from the southwest drifted the light fresh snow, picking it up in lower-angled fetch areas on the windward side of ridges and redepositing it as stiffer wind slabs on steep lee slopes and around terrain features near the ridge tops.
- Today, people could trigger shallow, soft wind slabs up to around a foot deep,and some of these could be quite sensitive.
- Some wind slab avalanches could be triggered remotely--(from a distance or from below).
- Soft slabs of wind-drifted new snow formed in and around terrain features like sub-ridges, rock outcroppings, gullies, and mid-slope rollovers.
- Beware if you cause cracking in stiffer drifted snow. Shooting cracks and whumpfing are obvious signs of instability.
- Even small avalanches can be quite dangerous if you are carried into trees or other terrain traps below.
