Avalanche Forecast
Regions: Jasper.
Weather Forecast
Monday and Tuesday will be progressively warmer. We expect good recovery on Monday night, but temperatures will continue to warm on Tuesday with the freezing level staying around 2400m into Wednesday. The weather is expected to deteriorate by Wednesday afternoon bringing some light precipitation with the warm temperatures.
Snowpack Summary
Pockets of wind slab are present in the upper alpine from previous strong winds last week. At treeline, lee aspects have a series of windslabs layered with thin weaknesses in the upper snowpack. A strong midpack bridges over weak basal facets on Northerly aspects at treeline and above.
Avalanche Summary
Several natural cornice failures to size 2.5 noted in the icefields area on North and Easterly aspects. Intense solar radiation will likely increase the cornice falls and initiate afternoon wet loose avalanche conditions in the next few days.
Confidence
Timing of incoming weather systems is uncertain on Wednesday
