Points saillants

Choose low consequence terrain.

Conditions are variable throughout the region, conservative decision making is the answer to this uncertainty.

    Probabilité

    Taille
    1.5–2.5

    Storm slabs will likely remain reactive. Human triggered avalanches are likely and natural avalanches are possible during periods of active loading.

    These avalanches could step down to deeper layers, resulting in larger avalanches.

Confidence

Low

  • We are uncertain due to a limited number of field observations.
  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

A  natural avalanche cycle started on Monday but  observations have been limited in this region due to poor visibility. Avalanches have been observed up to size 3 in the northern part of the region.

Snowpack Summary

Recent snowfall amounts throughout the region have been variable; up to 80 cm of storm snow has been redistributed into deep deposits on north and east aspects. Ongoing rain has saturated the upper snowpack below treeline. A thick crust from earlier this month can be found down 50 to 80 cm at treeline and below.

The early February crust, with facets above it, can be found down 150 cm.

The remainder of the snowpack is well settled and bonded.

Weather Summary

Wednesday Night
Mostly cloudy. 5 to 10 cm of snow at treeline, rain at lower elevations. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1800 m.

Thursday
Mostly cloudy. 1 to 15 cm of snow at treeline, rain at lower elevations. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Friday
Mostly cloudy. 10 to 25 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Saturday
Mix of sun and clouds. 2 to 10 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Avoid areas with overhead hazard.
