Avalanche Summary
No new avalanches reported or observed today.
Snowpack Summary
Sun crusts continue to form on steep solar aspects. Generally a weak snowpack. The surface wind slab at tree line and above is slowly gaining strength but is still producing planar results down 20cm from the surface. Natural avalanches are possible and the consequences would be significant because any trigger would likely make the entire snowpack slide.
Weather Summary
Sunday: A mix of sun and cloud with isolated flurries throughout the day.
Day time highs of -10 and 20-30km/h SouthWest winds.
MondayMonday: Mostly a snowy day with a forecasted 15-25cm. Freezing level will rise to 1800m (spray road elevation) Winds will be 40-50km/h out of the southwest

Terrain and Travel Advice
- Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
