Avalanche Summary
Over the weekend, numerous storm slab avalanches were reported size 1-2 on all aspects and elevations. They were triggered naturally, by skiers, vehicles and explosives. Some were triggered remotely or sympathetically. Slabs were up to 60 cm deep and ran on a crust or facet layer beneath the storm snow.
Snowpack Summary
50 to 80 cm of snow fell over the weekend. Near ridgetops, recent moderate to strong southwest wind has loaded recent snow into leeward terrain features. Near the coast, the storm snow may contain a thin crust from a brief temperature spike on Friday.
This recent snow is bonding poorly to an underlying weak layer formed during the January drought. Depending on aspect and elevation, the layer may exist as a hard crust, faceted grains and/or surface hoar.
The mid and lower snowpack is well-settled and bonded with no other layers of concern.

Terrain and Travel Advice
- Keep your guard up as storm slabs may remain sensitive to human triggering.
- Conservative terrain selection is critical; choose gentle, low consequence lines.
- Avoid lee and cross-loaded slopes at alpine and treeline elevations.
Problems
Storm Slabs
Storm slabs sit over a weak layer and remain triggerable by riders. The most likely places to trigger an avalanche are in wind-loaded lee terrain features just below ridgetops and convex rolls.
