March 24, 2013 at 7:00 am In near and above treeline terrain, a few isolated pockets of MODERATE avalanche danger may remain on NW-N-NE aspects on slopes 35 degrees and steeper due to lingering wind slabs. Below treeline pockets of MODERATE avalanche danger may form due to daytime warming on the sun-exposed E-SE-S-SW-W aspects on slopes steeper than 35 degrees. |

April 7, 2013 at 6:40 am For most of today, avalanche danger will remain LOW for all elevations and aspects. Very isolated pockets of lingering wind slab may exist in recently wind loaded areas above treeline. After 5 pm today, pockets of MODERATE avalanche danger are expected to form in near treeline and above treeline terrain mainly on N-NE-E aspects as additional snowfall and wind create new wind slabs. |
