Avalanche Advisory
Advisory: Salt Lake Area Mountains Issued by Brett Kobernik for Monday - January 26, 2015 - 6:54am
bottom line

The avalanche danger may rise to CONSIDERABLE during daytime heating. I am quite unsure just how the snowpack will react to the anticipated very warm temperatures so forecast confidence is low. Avoid being on or below steep sunny slopes as they heat up starting with east facing first and working south then west as the sun moves during the day. Today is an obvious day to avoid slopes like the southeast face of Mt Superior.




current conditions

Wow. Temperatures have been increasing over the last 6 hours and are in the mid 30s to 40 degrees along the ridges already. Wind speeds increased for a period overnight but have really backed off now and are from the northeast.

recent activity

There were a number of skier triggered wet loose avalanches on Sunday. One was on a steep east facing slope in the lower Meadow Chutes. DETAILS An other was a bit larger on the southeast face of Mt Superior mid day. A few more were reported on Superior late in the day as well.

description

Record high temperatures today will demand you pay attention to the sunny slopes. There are some factors which make me think we won't see too much wet activity but other factors and the unprecedented high temperatures make me very unsure. IF we see wet avalanches, they could pile up some substantial debris.

A number of people were ascending and descending the southeast face of Superior late morning and into the afternoon on Sunday. Snow safety teams at Snowbird, Alta, UDOT as well as Powderbirds and any savvy backcountry skiers who watch the spectacle scratch their heads at this. If you are unaware of why they scratch their heads it's because steep southeast facing slopes are the first to heat up and have the most likely chance for wet avalanche activity mid day. If you get it early enough, no worries, but during the heat of the day is a different story.

On a side note, this is an ongoing issue on Mt Superior. My own thoughts on this make me wonder how long UDOT and the Sherriff will watch people trigger avalanches above an open road. I hate to say it but I suspect we will see closures of this terrain at some point. It is not unprecedented, look at Roger's Pass:

WPA is "Winter Prohibited Area"

WRA is "Winter Restricted Area"

weather

It's going to be a warm one with ridgetop temperatures perhaps reaching 45 degrees. Winds will be pretty light from the east and southeast. We have an odd storm that will move through from the south on Tuesday into Wednesday but it's not looking all that great for much more than about 3 inches of snow, 6 inches if we're lucky.
