Avalanche Advisory
Advisory: Provo Area Mountains Issued by Evelyn Lees for Tuesday - January 21, 2014 - 7:58am
bottom line

The avalanche danger is MODERATE on mid and upper elevation slopes. On slopes facing northwest through southeast, the concern is triggering a deeper slide breaking on facets. Avoiding terrain steeper than 35 degrees and thinner snowpack areas can reduce your chance of triggering a slide.

On slopes facing east through south through west, the avalanche danger of wet sluffs increases to MODERATE each day with heating.




special announcement

The Snowbasin Freeride Avalanche Workshop will be held Jan 26-28. This is an avalanche & mountain safety skills workshop for freeride skiers & snowboarders riding & filming big lines. Details and Registration here. Brought to you by the Utah Avalanche Center, Snowbasin, Salomon, Atomic, & Suunto.

We have switched to a new SLC email advisory system. If you would like to get the daily advisory by email, or if you have been getting the advisory by email since the beginning of the season and wish to continue, you will need to subscribe here.

current conditions

Under clear skies, it’s another mild morning with mid and upper elevation temperatures in the upper 20s to low 30s. The westerly winds are very light, with almost all stations averaging less than 15 mph, and only the occasional gust in the 20s. There is not a lot of pizazz in the backcountry snow conditions these days, but it could be worse…

With good timing, the softening crusts provide corn-like conditions on the sunny slopes, and there is still a bit of cold dry snow on upper elevation, northerly facing slopes.

recent activity

No backcountry avalanche activity has been reported the past 2 days, with the last slides on any of the faceted weak layers the 14th (Ogden), 17th (Provo) and 18th (PC side).

Each day there are fewer places where a person could trigger a deeper slide failing on facets, yet the size and consequences of these slides isn’t decreasing. It’s tricky “slope forecasting” these days – a single slope can have stronger snow in one spot, be completely faceted in another, yet still have a portion where a slab could be triggered.

If you are getting onto steep terrain on northwest through easterly facing slopes, avoid the steepest portions of the slope and the thinner snowpack areas, such as a rocky spot or a steeper break over. Think defensively, so should your stability evaluation be wrong, you have an escape route planned and avoided a line with bad consequences – where you would be sent off cliffs or into a terrain trap such as a gully.

To quote our observer Dave Kikkert –“it’s spring timing for the sunny slopes, so don’t over stay your welcome”. Start early and get off the steep, sunny slopes before the snow goes from soft to sloppy, and avoid slopes where you could get washed into a gully. Also avoid travel on or below the large slumping cornices.

weather

I’m becoming a little weary of this winter – strong high pressure will bring another clear, sunny day with high temperatures near 40 at 8,000’ and right around freezing at 10,000’. The westerly winds will remain light, averaging less than 10 mph at most stations. A weak disturbance Wednesday into Wednesday night will temporarily drop temperatures about 10 degrees and possibly bring a dusting of snow.

general announcements

This information does not apply to developed ski areas or highways where avalanche control is normally done.  This advisory is from the U.S.D.A. Forest Service, which is solely responsible for its content. This advisory describes general avalanche conditions and local variations always exist.

If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
