In sintesi

Today the avalanche danger is MODERATE on steep slopes that have recent deposits of wind drifted snow. Avoid slopes with a smooth rounded appearance or that show signs of instability such as cracking in the snow surface. There also remains an isolated, or MODERATE danger for avalanches stepping down 2'-4' deep into buried, persistent weak layers of loose, sugary, faceted snow. Northerly facing slopes with steep, rocky, and more radical terrain are the most suspect for this type of avalanche.

    Winds over the past couple of days have shifted from SE-NE-NW and aback again, easily blowing and drifting Tuesday's 6" of low density snow around. Today's NE winds will continue to move snow around. Be on the lookout for fresh deposits and newly formed stiff slabs, on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain. Avoid slopes with a smooth rounded appearance or that show signs of instability such as cracking in the snow surface.

    On upper elevation, northerly aspects, snow has been sitting around on the ground since October. This has formed a persistent weak layer of loose, sugary, faceted snow that makes an unstable base for new snow on top. In some areas it may be possible to trigger an avalanche 2'-3" deep down to these weak, sugary snow. Areas of steep, radical, and wind loaded terrain that faces the north half of the compass are where you are most likely to encounter this problem.

Snow and Weather

Skies are clear, NE winds are blowing 15-20 mph on Abajo Peak, and it's 4 degrees at Buckboard Flat. Temps today will creep up into the high teens, but continued light to moderate NE winds will keep a serious chill in the air. Dry weather with gradually warming temps will continue through the week with our next chance for snow looking like around Sunday.

The Abajo Mountains picked up 6"-8" of snow from Tuesday's storm and conditions are slowly but surely improving. Unfortunately, winds have had their way with the snow surface in exposed areas and you'll have to seek out more sheltered locations to find powder. Low snow conditions still exist so beware of buried land mines such as rocks, and downed trees. Base depth at Buckboard Flat is 20".

Snow totals at Buckboard Flat (8924')
