Regions

South Columbia.

Localized flurries could cause sudden changes to the weather on Sunday. Normal cautions should guide you around sun-exposed slopes and isolated wind slabs.

Confidence

Moderate - Timing or intensity of solar radiation is uncertain

Weather Forecast

SATURDAY NIGHT: Partly cloudy, light southwest wind, alpine temperatures drop to -3 C.SUNDAY: Scattered flurries with sunny breaks and localized accumulations of 5-10 cm at higher elevations, gusty wind during the flurries, freezing level to 1900 m.MONDAY: A mix of sun and cloud, light north wind, freezing level to 1900 m.TUESDAY: Sunny, light wind, freezing level to 1900 m.

Avalanche Summary

Loose wet avalanches on south-facing slopes have been the predominant type of avalanche activity over the past few days. Small (size 1) wind slabs in the alpine have also been reactive to human triggering over the past week, but activity has dwindled recently.On Sunday, watch for loose wet avalanches if the sun pokes out, and remain cautious of wind slabs.

Snowpack Summary

Most slopes have entered a daily melt-freeze cycle, with the exception of north-facing terrain above 1800 m. On these colder slopes, you may find 10-20 cm of powder or isolated wind slabs. These same slopes may also have a layer of faceted grains buried 50 to 70 cm below the surface, but this layer has shown signs of strengthening. Elsewhere, the surface has been melting each day and then freezing into a hard crust overnight. Snow is disappearing rapidly at lower elevations.
