THIS AVALANCHE ADVISORY EXPIRED ON December 30, 2017 @ 5:28 am
Avalanche Advisory published on December 29, 2017 @ 5:28 am
Issued by Andy Bond - Taos Avalanche Center

LOW avalanche danger continues throughout the forecast area at all elevations today.  Triggering an avalanche is unlikely. Continue to use normal caution when traveling in the backcountry.  Snow is confined to north aspects above 11,000'.  If traveling in this terrain be aware of small isolated wind slabs on top of weaker snow.

Triggering an avalanche today remains unlikely. A thin variable snowpack exists with most slopes not holding enough snow to avalanche. Any potential hazard will be found on northwest through northeast aspects where moderate to strong winds have produced small isolated surface slabs.  It's where these slabs sit on top of weak faceted snow that there's potential to trigger an avalanche.  Most of these slabs are not continuous and would only produce a small avalanche.  We'll be stuck in low avalanche danger for a while longer until we get a storm producing cohesive slabs capping our weak snowpack. 

advisory discussion

Generally safe avalanche conditions exist in New Mexico's Sangre de Cristo mountains.  This won't change until we get more snow, which is looking increasingly like we'll have to wait until 2018.  The beginning to the 2017/2018 winter season has a good chance as going down as one of the worst starts on record.  The totals so far this year read more like a storm total from a one day storm last year.  14" of snow and 1.2" of snow water equivalent is all we've seen so far in November and December, with our last snow falling on 12/23.  Most of the storms this year have stayed well to our north. Hopefully the start of the New Year will be kinder to us.

Avoiding avalanches today is easy as most slopes are back to bare ground or consisting of non-continuous patches of snow.  Isolated danger can still be found on higher elevation northwest through northeast slopes below ridgelines and in cross loaded gullies where you can find slabs of harder wind blown snow.  These slabs, in many places, are resting on weaker sugary like snow near the ground.  If you find this slab/weak layer combination, the potential is there for a small surface slab to step down into deeper weaker layers.  Any avalanche would be small but with limited snow coverage lots of ground hazards still exist.     

We're committed to producing a product you want to see.  The lack of snow has made it hard on us at the Taos Avalanche Center in year two of operation, but we'll stay positive, as we have a lot of the winter season still left.  For many of us, we haven't had the opportunity to play with our new gear in the snow yet. Here's a great article from Doug Chabot with the Gallatin Avalanche Center in MT about the importance of being prepared when traveling in avalanche terrain.  As we wait for snow, it's a great time to get you're hands on your gear and know how it all works.   If you find yourself traveling elsewhere in search of powder, be sure to check out the local avalanche advisory on Avalanche.org for the area you're in!

recent observations

This long dry period has allowed us to get out into a lot of different areas of our forecast area.  We have more snow in the Williams Lake area with snow still lingering on north and some east aspects.  Patchy snow can be found below treeline with any semblance of a snowpack existing above 11,000' on northerly aspects.  The "snowpack" is anywhere from 2 to 12" primarily consisting of facets.  Isolated pockets of wind slabs can be found at higher elevations on northerly aspects often times resting on top of weak faceted snow.  We've found these pockets to range anywhere from 1 to 3' in depth.

Weather and CURRENT CONDITIONS
weather summary

Another "fall" like day is on tap with temperatures well above normal for this time of year.  This will last through Saturday before a cold front pushes in for Sunday bringing temperatures back to normal levels.  Both the GFS and the ECMWF longterm models are hinting about a pattern shift with an upper low developing off the SE California coast bringing much needed precipitation to southern California.  It's still a long ways away so we won't place any bets but at least it's something!
