Avalanche Forecast

Moderate

Reports from the early stages of the storm include a few small (size 1) storm slabs triggered by skiers (an example in this MIN report from Sky Pilot). We suspect some natural avalanches occurred later during the peak of the storm on Sunday, most likely on wind-loaded slopes.

Sunday's cold front will have left 20 to 30 cm of new snow across the region. Storm snow overlies a crust at treeline and below. In the alpine, the snow is heavily wind-affected and sits over a variety of layers including dry snow and wind slabs on north aspects and sun crusts and wind-pressed snow on south aspects. Several crusts can be found in the upper snowpack. The lower snowpack is strong and bonded.

Sunday night

Cloudy with scattered flurries bringing 5 to 15 cm of snow, 30 to 40 km/h southwest wind, treeline temperatures drop to -10 °C.

Monday

Cloudy with flurries starting mid-afternoon with up to 5 cm of snow by the evening, 40 km/h southeast wind, treeline temperatures warm to -5 °C.

Mostly cloudy with scattered flurries bringing 5 to 10 cm of snow, 20 km/h southwest wind, treeline temperatures around -5 °C.

Scattered flurries bring another 5 to 10 cm of snow, 30 km/h southeast wind, treeline temperature climbing to -2 °C.

• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Carefully monitor the bond between the new snow and old surface.
• Be especially cautious as you transition into wind affected terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
