Good morning, this is
in the back door from the south, a small storm has added 3 to 6” of snow in the
Logan and Ogden area mountains, 5 to 8” on the
and riding conditions will be greatly improved, especially in the Cottonwoods
and on the
Today’s avalanche danger will be exactly where the best turning and riding conditions are – on steep, upper elevation northerly and easterly facing slopes that had a pre existing snow pack. I expect most of the activity to be the new snow only, with human triggered loose sluffs and soft slabs possible on steep slopes. The light fluff that fell Wednesday could act as the weak layer. Deeper in the snowpack, there are also weak layers of faceted snow. On a few slopes, it may be possible for people to trigger a slide breaking on this more deeply buried sugary layer. Because these facets are very variable, I would expect any activity on this layer to be very pockety in nature. (Click here for a snowpit) But remember, being caught in any size avalanche can be dangerous, especially this time of year where even a small ride can sweep you through terrain features such as rocks. No avalanches were reported yesterday, and in spite of strong winds, the drifts that formed were generally pockety and not sensitive.
So start thinking avalanche as soon as you leave your vehicle: jump on test slopes, and perform lots of hand pits and pole plants, try to get a feel for the bonding of the new snow and the variability of the old snow. Be alert for any collapsing or whoomphing, an indication the older faceted snow is failing.
Moisture continues to stream northward from Pacific storm system centered to the south of us. Light to moderate snowfall should continue most of the day, with an additional 5 to 9” possible. Winds will gradually shift to the northwest and continue to decrease, into the 5 to 10 mph range, with gusts less than 25 mph. Temperatures will cool into the low teens at 10,000’ by afternoon. Snowfall will taper off this afternoon as the storm pulls to the east, and skies will become partly cloudy tonight, with only a few lingering snow flurries. The westerly winds will be light, and temperatures will drop to near 10. Sunday will bring increasingly strong southwesterly winds, increasing the avalanche danger.
