Avalanche Forecast

Only trace amounts of precipitation for today as an upper ridge of high pressure builds over the province. Expect moderate SE winds, freezing levels to 1700m and alpine high of -1. Warm and wet southwesterly flow resumes early Monday morning with the arrival of a pacific front. Expect 7cm of accumulation above 1800m and rain below.

Intense rain in the last three days has left the upper snowpack moist or wet to around 2100m. Above 1900m there is 70-80cm of heavy storm snow. The Jan 30 surface hoar/crust layer, up to 2200m, is down 50-90cm and depth will depend on elevation. Jan 15 surface hoar layer is down 100-150cm and was reactive in artillery highway avalanche control.

Observed several new large natural avalanches yesterday in the Highway Corridor. Most of the new slides began dry and ended moist, terminating farther than previous artillery triggered avalanches and in some cases gouging into existing debris.
