Surprisingly there are still a few slots left for our 3 day avalanche workshop scheduled for next weekend. Contact the Black Diamond retail store to sign up, this is sure to fill soon.
Winds continued overnight along the higher ridges gusting into the 60s and 70s and also gusting into the 20s along the mid elevation ridges. Temperatures were in the upper teens at the higher locations and in the mid 20s in the 7 to 8000 foot level.
Snow and Avalanche Discussion:
No significant avalanche activity was reported from the backcountry on Friday however there were crowns and debris visible from the natural avalanche event on Thursday. UDOT avalanche control work did produce a couple of slab avalanches in Big and Little Cottonwood canyons on Friday (PHOTO1 PHOTO2) but it sounds like not quite as much activity as expected. There were plenty of reports of upside down and variable snow from Friday. (Observations) Most people found the wind slabs that formed over the last few days were stubborn and not reactive. People could get some larger chunks of cornices to break but they were also stubborn and produced no avalanching upon hitting the slopes below them. I would note that we didn’t get any reports from people getting into the really exposed upper elevation terrain on Friday where things were still getting loaded and probably a bit more sensitive.
We have two things to consider today in the backcountry. If you’re skiing, snowboarding or snowmobiling in the high country you’ll want to continue to watch for lingering wind slabs that may still release with the weight of a person. These are scattered around on numerous aspects and elevations but more dangerous at higher elevations.
The second concern is warmer temperatures but it looks like they’ll mainly affect lower elevation terrain today. An abundance of snow along the foothills and mountain valleys this year demands that we adjust our behavior a bit. Gully bottoms and steep embankments should be avoided today especially if the sun pops out. Boy Scout leaders should keep scouts out of this terrain today. People in residential areas that have huge amounts of snow need to be careful of avalanches coming off of their house roofs. Southerly slopes should be monitored at the higher locations as well today especially during periods of clearing. If you are in higher terrain and exit out lower elevations don’t forget to watch where you are and avoid terrain traps.
Bottom Line for the
The avalanche danger is mostly MODERATE this morning especially in the low and mid elevations. This means human triggered avalanches are possible. There are a few pockets with a CONSIDERABLE danger along the more exposed ridgelines where wind loading continues. Warming temperatures may make the danger rise to CONSIDERABLE at lower elevations as the day progresses.
We’ll see the westerly winds continue this morning before slowing later today. We’ll see partly cloudy skies with a slight chance of a snow flurry. Temperatures will reach into the upper 20s at 8000 feet and low 20s at 10,000. Temperatures will reach near 40 at lower elevations. Warmer temperatures and more clear skies are in store for Sunday.
