Points saillants

Significant avalanche activity should remain unlikely today since old snow should remain frozen and the forecast only calls for limited amounts of new snow. Variable and firm snow conditions in the backcountry could present challenges for backcountry travelers. LOW avalanche danger exists at all elevations.

    Clear skies and near-freezing temperatures should have allowed snow surfaces to refreeze during the night. Expect to find mostly firm conditions in the backcountry today since colder temperatures and increased cloud cover should keep most slopes frozen. Small amounts of new snow on these firm surfaces may result in "dust on crust" conditions this afternoon.

    Some fresh snowdrifts may form on leeward aspects near ridgelines later today, but they should remain limited in size and distribution since only 2 inches of snow is forecast. If more snow falls than forecast, then some more problematic wind slabs may form in the most heavily wind-loaded areas.

    Avalanches should remain unlikely today, but still travel using normal caution and reinforce good habits. Making a plan that matches your group's skills and goals can lay the groundwork for an enjoyable day in the mountains despite potentially firm and challenging conditions.

Avalanche Discussion

* Warm sunny weather left wet snow on sun-exposed aspects yesterday. In many places, the wet snow rested on top of cold snow and created heavy sticky conditions.

* Shady slopes held breakable crusts and firm snow on the surface. 

* Several small loose wet avalanches (size D1) occurred around the forecast area over the past few days.
