Avalanche Forecast

High

Storm slabs were widespread and touchy on Friday. Avalanches were easily triggerable in any terrain over 30 degrees. Check out the easily skier-triggered slab at 0:40 in North Shore Rescue's Avalanche Conditions Report. Slabs were 30 to 40 cm deep, propagating as wide as 100 m and running on the old crusty and faceted surfaces.

50 to 70 cm of new snow has accumulated since Thursday night. Near ridgetops, strong southwest wind has loaded new snow into leeward terrain features. The new snow is not expected to bond well to underlying surfaces including a hard crust, facets and/or surface hoar.

The mid and lower snowpack is well-settled and dense with no layers of concern.

Check out the snowpack discussion starting at 1:57 in North Shore Rescue's Avalanche Conditions Report from Friday.

• Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
• Don't let the desire for deep powder pull you into high consequence terrain.
• Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
