    Ongoing strong northwest winds will contribute to wind slab development. Watch for triggering below ridgecrests and in gullies.                                                                  .

    A mixed bag of weak interfaces is buried about 20-30 cm down. The nature of these weaknesses varies greatly from valley to valley.

Avalanche Summary

No new avalanches have been reported from the region

Snowpack Summary

Westerly winds have shifted variable amounts of recent snow into wind slabs on lee slopes. A weak interface buried on Jan 23 is down about 15-35 cm. The nature of this interface varies considerably from place to place. In most locations it appears to be well bonded. Buried surface hoar was found in the north Elk Valley, but this is likely to be a localized problem. The lower snowpack is generally well-settled.
