Special Announcements
The report from Friday's avalanche accident is finished and can be found HERE. Our deepest condolences go out to the family and friends that are effected by this accident.
Weather and Snow
This morning under mostly clear skies, mountain temperatures are in the upper teens to low 20's F. A few trail heads have temperatures in the single digits F. Winds are blowing 10-15 mph from the southwest with a few gusts reaching 20 mph.
Today high temperatures should climb into the upper 30's F but it will feel a warmer than that in the strong sunshine. Winds should increase by about five mph.
Big picture - The ridge of high pressure is starting to flatten and move east. Snow should arrive Saturday morning and last into early next week. Fingers crossed.
Recent northerly winds damaged the powder on some slopes and southerly facing slopes have a crust. However, soft settled powder can still be found on many slopes. Easterly facing slopes may have the best snow.
Snow depths are about 5 to 5 1/2 feet near Snowbasin and Ben Lomond. Further east near Powder Mountain and the Monte Cristo area snow depths are about 4 feet.
Recent Avalanches
No new avalanches were reported from the backcountry in the Ogden area. However, there have also been some large, deep, slab avalanches breaking on a persistent weak layer of facets in the Uinta Mountains. If you're headed into those mountains check out some of the recent slides in that area HERE.

Description
The Ogden area mountains generally have a strong snowpack. There were some buried weak layers but these have healed and gained strength and no produced and recent avalanches. Look for isolated wind drifts that could be unstable. While this is a low likelihood issue, any slab of wind drifted snow could have severe consequences in extreme terrain. As always be cautious around cornices that can break in surprising ways.
Looking ahead - warm sunny days and clear cold nights are a good recipe for creating facets near the snow surface which may become a new persistent weak layer. We'll be watching the snow surface this week and watching what this weekend's snow falls on. If the powder this week seems to "dry out" or get better, that's a good sign that the faceting process is occurring. Stay tuned.
