Avalanche Forecast - Eastside Region

  • Alpine: Moderate
  • Treeline: Moderate
  • Below Treeline: Low

<p>If you&rsquo;re seeking cold, dry snow in alpine chutes, it&rsquo;s possible that you could trigger a wind slab avalanche below the ridge or mid-slope. As temperatures climb, cold snow can become sticky, leading to wet loose avalanches on steep, rocky slopes that receive direct spring sunshine. Watch for shooting cracks in drifted snow and rollerballs as the first signs that you&rsquo;ve found the problems. You can shift to lower slope angles and simpler terrain to avoid both problems.&nbsp;</p>
