Highlights

A cold and strong winter storm will impact the Logan Zone today, and the avalanche danger will increase with heavy snowfall and drifting from westerly winds. Heightened avalanche conditions and MODERATE danger will likely develop on many slopes by late afternoon. Rain overnight on remaining saturated lower elevation snow increased potential for loose wet avalanches, and these could gouge to the ground and entrain large piles of heavy debris. The winter storm will cause avalanche danger to rise and become more widespread tonight and tomorrow.

    Sun may pop out from behind the clouds this morning, and last night's new snow will quickly become moist with seasonal warm temperatures. People could trigger small loose avalanches consisting of moist surface snow on steep upper elevation slopes. A strong winter storm will impact the Logan Zone today, and rapid accumulations of heavy snow and drifting from southwest winds will cause rising danger and heightened avalanche conditions on upper and mid elevation slopes. Avalanches are possible, and people could trigger shallow soft slab or loose avalanches of fresh storm snow on steep upper and mid elevation slopes later this afternoon.

    Rain fell on the saturated remaining snow at lower elevations overnight. Loose wet avalanches entraining cement-like piles of debris may be possible for people to trigger on very steep slopes, and some natural activity may occur today.
