Summary
Weather Forecast
Expect a mix of sun and could today. Freezing levels are forecast to rise to 2000m, winds will be moderate from the SW, and we may get a trace of snow this morning. Similar weather conditions can be expected tonight and tomorrow. No significant snow is forecasted until the weekend, where we may see up to 25cm of new snow.
Snowpack Summary
Since Friday, Rogers Pass has received ~95cm of snow at treeline. The storm came in with warm temperatures and moderate to strong wind, forming storm slabs. These storm slabs remain reactive to skier triggering on specific terrain features in the Alpine and at Treeline. The March 18th layer is now buried 60-100cm depending on aspect and elevation.
Avalanche Summary
A skier accidental occurred yesterday on Teddy Bear Trees. The slab avalanche was at least a size 2.5, failing either as a storm slab, or on the March 18th persistent slab interface. Field techs will investigate further today. Another MIN report of skier accidentals and remotes in the Hermit Moraines area yesterday, click here for more details.
