Summary
Weather Forecast
A NW flow to the upper atmosphere with cold air to the NE will keep temps cool despite the opportunity for solar input. Upslope conditions and zonal flow over the mountain will yield light precipitation. Clearing slightly on Wed with a shallow ridge then back to a W flow for Thursday.

Snowpack Summary
Moist new snow, more in the front ranges on a supportive melt freeze crust exists on all aspects, BTL and solar aspects at TL and Alp elevations. Snowpack has yet to have a deep melt freeze cycle and basil weakness is still a looming hazard sensitive to large loads like cornices.
Avalanche Summary
No new alligators observed or reported.
Confidence
Due to the number of field observations
Problems
Wind Slabs
Possibility new snow with varied consistency depending on elevation. Slabs may be limited to TL elevations but depends on condition of old surface, which is quite varied across the region.
- If triggered the loose wet sluffs may step down to deeper layers resulting in large avalanches.
- Use extra caution on solar slopes, or if the snow is moist or wet.
Aspects: North, North East, East, South East, South.
Elevations: All elevations.
Likelihood
Expected Size
Deep Persistent Slabs
This problem will require a large trigger, thin spots, increased loading or rapid day time warming.
- Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.
- Avoid shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: All elevations.
