Weather Forecast

Out with one storm and in with another. A short reprieve from snow and broken skies for Monday before a second storm comes in by Tuesday afternoon. Expect 10 - 20cm by Monday morning in the icefields area with gusty SW winds at ridge top.

No new natural activity reported from a field teams on Sunday. Poor visibility made any alpine or treeline observations impossible. Expect increased likelihood of avalanches with the outgoing and incoming storm on Tuesday/Wednesday.
