Avalanche Forecast
Regions: Glacier.
Weather Forecast
A building ridge of high pressure will block precipitation today and deliver a mix of sun and cloud. Freezing levels are dropping and are expected to stay below 1400m today. Ridge winds will be moderate from the SW. A low pressure system moving through the area tomorrow will bring more light precipitation with another 7cm of snow for the weekend.
Snowpack Summary
7cm of new snow fell last night bringing the 3-day total to 30cm in the alpine. At lower elevations, we have had periods of rain. Storm snow at higher elevations sits atop a suncrust on solar aspects and surface hoar in areas sheltered from sun and wind. The top 20-50cm of snow is moist on all aspects to TL.
Avalanche Summary
Warm temperatures, precipitation and strong winds contributed to a widespread natural moist/wet avalanche cycle yesterday, especially at lower elevations. Avalanches were generally in the size 2-2.5 range, however there were some avalanches running up to size 3 in the highway corridor off of Mt MacDonald.
