Weather Forecast
2-4mm of precipitation is expected Wednesday overnight with moderate alpine winds from the NW. Unsettled conditions are expected for Thursday.

Avalanche Summary
Some small solar-triggered activity was reported on Monday and no new avalanches have been reported since. Avalanche activity is generally not expected for Thursday except potentially isolated human-triggered wind slab activity if we get more snow than forecast Wednesday overnight.
Snowpack Summary
The snow surface is highly variable and may include wind-pressed surfaces or old wind slabs, a sun crust on all solar aspects, surface hoar, surface facets, and/or up to 5 cm of soft snow over a widespread supportive rain crust in wind sheltered areas. The snowpack is generally strong and well settled. If we get enough snow Wednesday overnight, thin isolated wind slabs may form in immediate leeward terrain features in the alpine.
