Snowpack Summary December 31,
2021
Posted by Allen Giernet @ 8:15am
This summary applies to backcountry areas only.
The Bottom Line –
We will begin posting regular snowpack summaries once we build up a snowpack.
The avalanche center website should be back up and running for the first of the year.
Snow totals reported for the past two days range from 24” to 30” in the San Gabriel Mountains and 10” to over 12” for the San Bernardino Mountains. This is significant snowfall and human triggered avalanches will be possible. Our main concerns will be Storm Slab Avalanches especially above 8,000’ where there have been wide spread reports of an icy crust prior to the onset of the recent storm. There could be poor bonding and significant loading on all aspects above this elevations. The other concern will be Wind Slab Avalanches due to West to Southwest winds during the storm. There were also recorded Northerly winds at times in some areas. Wind Slabs development will be likely on SE,E,NE,N, and possible on NW,W & SW aspects. Use conservative decision making when venturing out and choose low angle terrain. Allow time for this snow to settle and be extremely wary of the potential poor bonding interface. We have very little first hand information at this time. Please submit any observations when you go out. Always travel with a partner and carry your avalanche safety equipment - Avalanche Transceiver, Shovel and Probe.
If you venture out please submit your observations to the avalanche center. All the
weather links and reports pages are working. Any info is helpful.
