Weather Forecast
Flurries continue for the next 24 hours. Accumulations and loading may vary significantly. Forecasted snow amounts are up to 7 cm in the Icefields area, with much less in the North. Freezing levels will fall to valley bottom overnight and rise to 1800m mid-day. Ridge winds will be mainly light and variable, with gusts into the moderate range.
Snowpack Summary
Up to 20cm of snowfall since Thursday and moderate SW winds have built windslabs in open areas at treeline and in the alpine, and continue to add to the cornice problem. Persistent instabilities (down 40-100cm) remain sensitive to triggering, especially on N slopes at treeline and in the alpine. The mid and lower snowpack remain weak and facetted.
