Storm slabs may be reactive to human triggering, especially in wind loaded areas, and at upper elevations. Watch for signs of instability such as whumphing, cracking and recent avalanches.
Fresh snow and wind will likely be creating storm slabs. With ongoing snow and wind in the forecast, storm slabs may become more reactive throughout the day.
Storm slabs will may be reactive throughout the region on Monday with new snow and strong winds in the forecast.
SUNDAY NIGHT - Mainly cloudy with isolated flurries, up to 5 cm / southwest winds, 40-60 km/h / alpine low temperature near -6
MONDAY - Cloudy with flurries, 5-10 cm / southwest winds, 60-100 km/h / alpine high temperature near -3
TUESDAY -Cloudy with sunny periods and scattered flurries, up to 5 cm / southwest winds, 30-50 km/h / alpine high temperature near -5
WEDNESDAY - A mix of sun and cloud with scattered flurries / light north west winds / alpine high temperature near -7
5-10 cm of new snow likely sits on a mix of melt-freeze crusts, hard wind slabs, sugary faceted snow, and feathery surface hoar crystals depending on location. Continued snowfall and high winds are expected throughout the day, bringing total new snow amounts to approximately 15-20 cm by the end of the day. Storm slabs will likely be reactive. Total snowpack depth ranges from 50-100 cm and tapers rapidly at lower elevations.
