We still don't have many alpine observations at this time. Given the current storm, watch for heavy spindrift in gullies and other confined alpine features, especially in and around terrain traps. SH
Summary
Weather Forecast
25-30cm in the alpine in the Little Yoho region by Sunday evening. Freezing levels to 2000m with moderate SW winds diminishing by Sunday night. Sunday night will see a cold front moving in and freezing levels dropping to valley bottom with a clearing trend.
Snowpack Summary
Below treeline and treeline elevations are below threshold depths for avalanches. At alpine elevations, a storm earlier in the week dropped 20-40 cm , and the current storm is forecast to drop 25-30 cm in the alpine by Sunday night. Much more snow has accumulated in gullies where spindrift has been filling them in.
Avalanche Summary
Limited visibility and observations today. There were reports of spindrift avalanches earlier this week. Some small slabs have been noted this past week and some reports of whumpfing in the high alpine. These have been small in size and distribution but should be of note on fans below gullies and unsupported slopes in alpine terrain.
Confidence
Problems
Loose Dry
Spindrift avalanches in lee gullies for ice climbers will be the biggest concern. These features will have the highest concentration on snow and are a good funnel for wind transport.
- Carry avalanche safety equipment on ice climbs in avalanche terrain.
