This does not include ski areas or highways where avalanche mitigation programs exist. * WHEN...In effect from Tuesday 5 AM PST to Wednesday 5 AM PST. * IMPACTS...Rapidly accumulating snowfall, weak layers in the existing snowpack, and gale-force winds that blow and drift snow have created dangerous avalanche conditions in the mountains.
