Human triggered avalanches will be possible on Monday with new snow and wind in the forecast. Keep your risk tolerance to a minimum while public health resources are strained.

A cold front crosses the region Monday morning.

SUNDAY NIGHT: 5-15 cm of new snow, strong southwest wind, freezing level drops to valley bottom, alpine temperatures drop to -8 C.

MONDAY: Another 5-15 cm of snow possible throughout the day, light to moderate southwest wind, freezing level around 1000 m, alpine temperatures reach -5 C.

TUESDAY: A mix of sun and cloud, light wind, freezing level around 1000 m, alpine high temperatures around -5 C.

WEDNESDAY: Sunny with a few clouds, light north wind, freezing level around 1000 m, alpine high temperatures around -5 C.

While recent avalanche activity has primarily been wet loose avalanches on sun-exposed slopes, the incoming weather will form fresh slabs. Human triggered slab avalanches will be possible on slopes that accumulate new snow, especially in wind loaded terrain. If you decide to travel in the backcountry, consider sharing your observations with us and fellow recreationists via the Mountain Information Network (MIN).

The past week of warm weather has formed moist and crusty surfaces which will be buried by 15-25 cm of new snow by Monday afternoon. There is some uncertainty about how well the new snow will bond to these interfaces. The snowpack is generally strong and settled, with the exception of some areas in the eastern and northern parts of the region that have weak faceted snow near the base of the snowpack. However, this layer is considered dormant and has not produced an avalanche since February 20.

• Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
• Minimize your exposure time below cornices.
