Regions

South Coast.

Keep in mind a spring snowpack can rapidly change in a short time, the likelihood of loose wet avalanches will increase as the snowpack warms.

Confidence

Moderate - Due to the number of field observations

Weather Forecast

MONDAY NIGHT: Cloudy with isolated showers, moderate southwest wind, treeline temperature +1 C, freezing level 1500 m.

TUESDAY: Cloudy with sunny periods, light northeast wind gusting to 35 km/h, treeline temperature +3 C, freezing level 1500 m.

WEDNESDAY: Mix of sun and clouds, light to moderate northwest wind, treeline temperature +4 C, freezing level 2000 m.

THURSDAY: Mostly cloudy, light to moderate northwest wind, treeline temperature +5 C, freezing level 2100 m.

Avalanche Summary

There have been no recent avalanche reports, but it is expected that a loose wet avalanche cycle occurred sometime Thursday-Friday during the last storm.

If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!

Snowpack Summary

Rain to mountain top has saturated the snowpack and the snowpack is rapidly melting. The snow surface may freeze overnight but should rapidly moisten during daytime warming.

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.
