Avalanche Forecast
Regions: Glacier.
Weather Forecast
Mainly cloudy today with isolated flurries, especially west of Rogers Pass. Freezing level will hover around 2000m with moderate to strong winds from the SW. Tonight will see a general clearing trend with freezing levels staying near 1900m. Tomorrow will see a heat wave roll through, with sunshine and freezing levels rising to 3700m.
Snowpack Summary
The west side of the Pass received up to 20cm last night, bringing the 2 day total to 35cm. East of the Pass received much less. Storm slabs are building with the mod/strong southerly winds in lee areas, more prevalent above 2400m where the snow is cooler. New snow is insulating a warm, moist snowpack, and multiple crusts exist in the upper metre.
Avalanche Summary
Very little activity was noted yesterday. Isolated avalanches to size 2.5 were observed from very steep, N-facing start zones on Mt Macdonald and Ross Peak, travelling as far as the top of the avalanche fan. A field team at the Illecillewaet Glacier toe noted 15-20cm of dry surface snow with over 50cm of weak, moist snow below.
