Over the last few days we have received incremental amounts of snow (5+”) and another 3-5” is expected today. Should snowfall become heavy and/or ridgetop winds pick up beyond the anticipated 10-20mph, be on the lookout for signs of instability. Plain and simple, if you observe any redflags (recent avalanches, shooting cracks, or hear “whumphing” sounds) choose gentle slope angles.
No new signs of instability have been observed over the past five days since a wet warm storm dumped an upwards of 4′ of heavy snow in upper elevations around Girdwood and Turnagain Pass. In general snowpack conditions have been stabilizing gradually and lots of high quality powder can be found. Caution is advised if poking into steeper terrain, especially on Northern aspects where it can be difficult to assess the snowpack due to generally higher consequence terrain, like cliffs, rocks, and badness.
Remember to always practice safe travel rituals on steep slopes, namely, only expose one person at a time, watch your partners carefully, and regroup in safe zones.
Snow coverage may still be thin near road level, but considering its early December Turnagain Pass is looking good!
Yesterday’s visibility finally allowed for a good look around Turnagain Pass to see some of the aftermath of our last storm. Debris was observed in some of the usual paths, but lots of steep terrain did not avalanche during this last cycle.
On leeward aspects where the snowpack is deep, over 4’ thick, stability is suspected to be pretty good, but there is still little known about windward aspects above 3000’, where the snowpack could be thinner. What we do know is 2-4′ of ‘Thanksgiving’ snow sits on top a variety of old surfaces, one of these being a layer of small facets near the ground. Again, caution is warranted in steep terrain, as an avalanche breaking in the facets near the ground would be large.
Light showery conditions have been the theme of the last 5 days. Winds have been light to moderate; mostly from the East/Northeast and temperatures have been mild, ranging from the mid 20Fs to low 30Fs.
Overnight 1 € of new snow has fallen in Turnagain Pass and 2 € in upper elevations around Girdwood. Temperatures have increased slightly into the low 30Fs at ~1000′. Winds have remained light out of the East/Northeast.
Today snow showers are expected to bring 3-5 € of new snow to the upper elevations near Girdwood and Turnagain Pass. Temperatures may increase above 32F, causing a mix of rain and snow for lower elevations. Easterly winds are expected to be 10-20mph near ridgetops.
