Monday, November 26, 2018
The avalanche danger is mostly LOW in the Ogden area mountains. There is a MODERATE danger for triggering a small slab avalanche in the highest northerly facing terrain, where some old snow may exist beneath the recent storm snow. Hitting rocks and stumps is almost certain.

Weather and Snow
The Thanksgiving weekend storm has settled, and the Ogden area mountains have one to 1 1/2 feet of snow on the ground at the mid to upper elevations elevations. Access is still tough, with only about 7" of snow at the lower elevations like the Ben Lomond trailhead. While the snow is becoming more supportive, hitting rocks and logs will be common with the overall shallow snow pack.
Temperatures are in the teens and twenties this morning. Skies will be sunny and temperatures warm today, with highs reaching mid 30s at the upper elevations. The northwesterly winds are less than 5 mph this morning, and even Ogden peak is only clocking in at 15 mph. Speeds should remain light through the day. Good news - more snow is on the way. Increasing clouds tomorrow, with a trace to a few inches of snow on Tuesday night, followed by a couple of stronger storms adding snow into the weekend.
Recent Avalanches
No recent backcountry observations were reported for the Ogden area mountains. Snow safety teams reported that no avalanche activity was observed.

Description
Most of the Ogden area mountains were snow free before the Thanksgiving storm. This means that many slopes do not have old, faceted snow. However, we have had reports of patchy old snow in the highest northerly facing terrain. I would approach any upper elevation north and northeast facing terrain with caution and for now assume there is old faceted snow that could produce a slab avalanche there. The good news is this is very isolated to steep rocky terrain and there is plenty of other slopes that do not have this problem.

Description
Most slopes in the Ogden area mountains were bare ground before Thanksgiving and have a low avalanche danger. Use normal caution - you may be able to trigger a few wet sluffs on the steepest sunny slopes as the snow heats up today, or crack out a small old wind drift along the high ridge lines. Hitting rocks and stumps remains the greatest hazard.
