Avalanche Forecast
Regions: Glacier.
Weather Forecast
A mix of sun and cloud accompanied by isolated convective flurries. Ridge winds will be west 25km/h gusting to 50km/h. Freezing levels stay below1400m, but the afternoon sun can have a profound effect on steep solar aspects at all elevations. Temperatures climb higher on Sunday moving us towards spring conditions with warm days and cool nights.
Snowpack Summary
10cm of new snow at treeline. Settling storm snow in the top 60cm overlies a series of crusts on most aspects up to 1900m. Strong to extreme winds in the high alpine have formed wind slabs on lee features. Cold, dry snow can be found on northerly slopes while solar aspects rapidly become moist with sunshine. Huge cornices line the upper ridges.
Avalanche Summary
Several large natural avalanches were observed in the highway corridor yesterday in the size 2.0-2.5 range. Two size 3.0-3.5 avalanches were observed on the north face of Mt MacDonald including a deep slab release that cleared trees and ran to the end of the run out zone.
