Regions

Waterton Lakes, Waterton.

We are in Spring Conditions. Avalanches are still possible.

Up to 25 cm of storm snow will see increasing solar radiation and decreasing cloud cover. Look out for signs of solar warming and wet loose activity as the forecast period progresses.

Confidence

Avalanche Summary

A few small loose avalanches observed, though field observations have been limited.

Snowpack Summary

10-25 cm of storm snow is quickly settling. Below it sits a series of melt forms and melt freeze crusts. The atmospheric river crust is down 50-70 cm. The mid and lower snowpack are well settled.

Weather Summary

Sunday

Sunny periods and isolated flurries. Alpine Low of -11 °C, High of -8 °C. W wind to 15 km/h. Freezing level at 1400 m.

Monday

Sunny with cloudy periods. Alpine Low of -9 °C, High of 0 °C. SW wind gusting to 25 km/h. Freezing level at 2100 m.

Tuesday

A mix of sun and cloud. Alpine Low of -4 °C, High of 3 °C. W wind gusting to 30 km/h. Freezing level: 2400 m.

Terrain and Travel Advice

Make observations and continually assess conditions as you travel.
Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
