Freezing levels climb to mountain tops today with steady rain.Avalanches could occur on old instabilities buried deep in the snowpack.




Avalanche Summary

On Sunday, a very large (size 3) avalanche was reported on Joffre shoulder in the Duffey lake area. With rising freezing levels and continued rain, it is likely that more of these avalanches will occur.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Up to 30 cm of recent storm snow is becoming moist and rain soaked below 2500 m. This snow rests over a crust on all aspects below 1800 m.

The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. It seems these layers may be coming reactive again with the warming and increased load from rain.
