Solar radiation and rising temperatures could increase the avalanche danger in the afternoon. Watch for overhead hazards such as cornices or sloughing from steep cliffs

Summary

Weather Forecast

A light snowfall is expected overnight in the Icefields area. Light winds are not expected to affect this snowfall or increase the avalanche danger. A clearing trend will develop through the week with clear skies and temperatures into the low teens.

Snowpack Summary

Suncrust on solar aspects. 5-10 cm over a supportive temperature crust can be found on all aspects tree line and above to 2500m. The weak basal facet layer is bridged by a strong mid-pack in most areas at treeline and above.

Avalanche Summary

Several recent cornice falls were observed on steep unskiable terrain which DID NOT propogate any avalanches on the slopes below.

Confidence

Timing or intensity of solar radiation is uncertain

Problems

Cornices

Cornice falls were observed on steep unskiable terrain on Northerly aspects. Avoid this overhead hazard while travelling since the warmer temperatures may increase the number of cornice failures.

Do not travel on slopes that are exposed to cornices overhead.Give cornices a wide berth when travelling on or below ridges.

Aspects: North, North East, East, South East.

Elevations: Alpine.
