Summary
Confidence
Poor - Due to limited field observations
Weather Forecast
Synopsis: A ridge of high pressure over southern BC should maintain dry conditions on Tuesday; however, expect thickening cloud as a frontal system approaches the region from the west. The system should give moderate precipitation on Wednesday and Thursday. Tuesday: Increasing cloud with flurries possible late in the day. Freezing level at around 500 m. Winds light from the southwest. Wednesday: Periods of snow – 5-10 cm. Freezing level at valley bottom. Thursday: Periods of snow or flurries – 5-10 cm. Freezing level at valley bottom.
Avalanche Summary
No new natural avalanches have been reported. Fresh wind slabs have been observed in exposed areas, but slope testing produced very few results.
Snowpack Summary
Expect to find wind slabs in exposed leeward terrain. A couple of notable weaknesses have been observed in the snowpack: first, a storm snow weakness (may also include small surface hoar) down 40-50cm. This layer should gain strength in the short term. Second, a facet/ crust combo that formed in early November is now down 40-70cm. This layer has produced moderate "drops" results in recent snowpack tests. Because this weakness is so close to the ground in most areas, associated avalanche activity will likely be limited to slopes with smooth ground cover (e.g. scree slopes, rock slabs, grassy areas, etc.). Snow depths vary throughout the region. Treeline depths in the southern part of the region (west of Smithers) are between 70 and 125 cm. Watch for early season hazards like lightly buried rocks or stumps and open creeks.
