Avalanche Forecast

Fair - Timing or intensity of solar radiation is uncertain on Monday

A ridge of high pressure with light winds and many sunny periods are expected on Monday over all of the interior regions. The airmass is still unsettled, and some areas may develop periods of convective flurries. A Pacific frontal system is forecast to move onto the coast during Monday evening, and should develop cloud and precipitation in the Interior around midnight. Expect winds to increase to moderate from the southwest and precipitation to be moderate to heavy by Tuesday morning. This system is expected to continue during the day and into Wednesday morning.

One operator reported that a snowcat remotely triggered a W-SW aspect slope in the alpine from 25 metres away that released on a persistent weak layer down close to 200 cm and resulted in a size 3.5. Explosive control on Saturday resulted in slabs that were 50-80 cm thick and up to size 2.0

Convective flurries resulted in another 10-20 cm of new snow across the region combined with light winds. There is a soft slab about 50 cm thick that is sitting on the recent storm snow. The combined slab above the mid-february persistent weak layer is now between 150-200 cm. Some operators continue to get easy-moderate sudden planar character shears on the mid-february surface hoar in shallow areas. The persistent weak layer continues to be a concern at all elevations, and may show wide propagations on low angle terrain below treeline. The new snow may consolidate and release naturally if the skies clear and we get some strong solar radiation. Snowpack conditions continue to be tricky to evaluate, and are variable throughout the region.
