    Steady snowfall and light to moderate winds may produce new windslabs in exposed areas.

Weather Forecast

Steady snowfall expected during the week, increasing in intensity by next weekend. Winds light to moderate from the Southwest. Temps warming up from the recent arctic condition but remaining cool with daytime highs in the -2C range at treeline. Freezing levels reaching 2000m by mid-week.

Snowpack Summary

Supportive mid-pack above 1900m. A persistent weak layer (Feb10 interface) can be found down 30-70cm and consists of decomposing surface hoar and or facetted grains. This appears to be bonding well and is mainly a concern on solar aspects (South and West). Recent moderate winds have created new windslabs in open areas above tree line.

Avalanche Summary

No new avalanches have been reported.
