NORTHWEST - Warmer air is forcing the rain/snow line (freezing level) in the Pacific Northwest and Northern Tier up to higher elevations. Rain and melting snow will increase the avalanche risk in the High Cascades, volcanoes, and mountains of British Columbia, Idaho, and Montana. These are sometimes referred to as 'wet avalanches'.


Forecast maximum daily freezing levels in the Cascades:

  • 3/26: 10,000ft

  • 3/27: 6,000ft

  • 3/28: 4,500ft

  • 3/29: 4,000ft

Forecast maximum daily freezing levels in NW Montana:

  • 3/26: 10,000ft

  • 3/27: 10,000ft

  • 3/28: 6,000ft

  • 3/29: 6,000ft
