South Coast

Fair - Timing, track, or intensity of incoming weather system is uncertain

The storm is expected to end on Sunday evening. A ridge of high pressure will build in the wake of the storm system. Dry, sunny conditions are expected for Monday into Tuesday. The next frontal system should reach the south coast on Tuesday night.Sat. Night/Sunday: Snowfall 25-35cm, freezing level am: 1800m pm: 1500m, ridgetop winds 30-50 km/h SW easing during the day.Monday: A mix of sun and cloud, light scattered flurries 0-3cm, freezing level am: 600m pm: 1000m, ridgetop winds light NWTuesday: A mix of sun and cloud, dry conditions with the possibility of light snow in the evening, freezing level am: 500m pm: 1200m, ridgetop winds light W-NW

No new reports from Saturday at the time of publishing.  Limited information from the Sea-to-Sky region suggests that the avalanche activity on Saturday was limited to wind loaded features.  Widespread activity is expected for Saturday night and Sunday as the storm progresses.

The new snow is sitting on a weak layer consisting of a well-developed sun crust on solar aspects, surface hoar in sheltered areas, and a widespread temperature/rain crust at lower elevations. Strong SW storm winds is forming new wind slabs on leeward slopes.The warm weather has resulted in good settlement of the snowpack and most of the layers are well bonded. There are still two weak layers that remain a concern but the problem is becoming isolated. However, the weight of the new storm snow may reactive these layers. Before the storm, the early March layer was down 60-100cm and the early Feb layer is down roughly 1.5m. It seems like these persistent weak layers are more of a concern in the northern parts of the region but may still pose a threat in the Coq and south.
