Avalanche Forecast
Regions: Glacier.
Weather Forecast
The Arctic ridge of high pressure will remain in place today keeping the weather cold and dry. Today expect a mix of sun and cloud and light Southwest winds at ridge-top. Alpine temperatures may(hopefully) reach -14*C. The Arctic ridge is expected to shift tomorrow which should allow warmer temps and some precip on the weekend and early next week.
Snowpack Summary
SW winds have created windslabs along exposed alpine ridges and cross-loaded features. These sit on a variety of old surfaces, from hard windslab to faceted soft snow in protected areas. The very cold temps and generally low snow have created a weak facetted snowpack. Field tests are producing mod-hard resistant planar results in the upper 60cm.
Avalanche Summary
Numerous loose and storm slab avalanches were observed Monday from Mt Macdonald and Mt Tupper on steep extreme terrain. This occurred during Monday's wind event and debris was observed to spread widely across the fans. A few natural size 1-1.5 slab avalanches, likely from Monday, were observed from steep N-facing terrain on Avalanche Crest.
