Waterton Lakes

It's the time of year where we are transitioning from winter to spring. Forecasted warm temperatures, high freezing levels and rain/snow in the next few days have the potential to change the snowpack quickly. Hazard can change throughout the day so use caution on warm days.

A few natural wet loose avalanches have been observed up to size 1.5 on solar aspects.

Sun crust on solar aspects, breaking down daily with daytime warming. Consolidated dry snow on polar aspects with the March 21st down 20 - 40 cm. The Feb 3rd crust/facet weak layer is buried 60-120 cm deep. Below this, the snowpack consists of a mixture of settled snow and crust/facet layers to ground. Snowpack depths between 80 - 250 cm.

• The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
• Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
