    Rain and warm temperatures may create the conditions for human and natural triggered avalanches.

    At upper elevations, if the snow fell instead of rain, watch for wind loading from southerly winds.

Terrain and Travel Advice

  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Confidence

Moderate

Avalanche Summary

There have been no reported avalanches in our region.

Please help out your backcountry community by submitting a MIN report if you head out to the backcountry.

Snowpack Summary

Rain and warm temperatures continue to affect the already shallow snowpack.

The top layer, 15 to 20 cm of previously wind-distributed snow, will become moist. This overlies a hard melt-freeze crust. Another crust with surface hoar above it can be found down 30 to 40 cm. We are not concerned about these layers at this time.

The snowpack has yet to cover many early-season hazards and large areas of terrain are below avalanche threshold. Only specific terrain features with smooth ground cover, gullies, or established avalanche paths are above the threshold for avalanches.
