Ogden Avalanche Advisory

Forecaster: Brett Kobernik


MODERATE: Natural avalanches are unlikely, HUMAN TRIGGERED AVALANCHES ARE POSSIBLE, larger avalanches in isolated areas are possible. MODERATE is not a LOW danger. People get injured and have been killed during a MODERATE avalanche danger rating.


Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The overall avalanche danger for both newer wind slabs and more persistent slabs is MODERATE. This means human triggered avalanches are possible. The distribution of these is scattered but some of them could be fairly big. Mid and upper elevation slopes facing northwest through east are the most suspect.


Temperatures dropped into the low to mid teens overnight with light northwest ridgetop winds. The mountains received a trace to a couple inches of new snow on Saturday that did include some graupel. Riming occurred in scattered areas where mid and low level clouds were present during the day. Out of wind and sun effected terrain, riding conditions aren't bad.


UPDATED: Large class 2 unintentionally skier triggered slide on 1-2-10 in Hell's Canyon. 6-10" deep, 50' wide ran 1700', 10' pile of debris. Unintentionally snowboard triggered slide on 1-2-10 in Toilet Bowl (north of Hell's) 6-12" deep, 70-90' wide, ran 200'. Also one intentionally skier triggered on 1-1-10 6-12" deep, 30' wide ran 600'. All slides were in areas with a previously shallow and very weak structure. Recent winds have helped the formation of the slab above the weakness.

Human triggered avalanches in the Salt Lake region were on Bountiful Peak, West Porter Fork in Mill Creek and Kessler Peak in Big Cottonwood. They were all on northeast facing aspects and all seemed to involve wind loaded terrain with last weeks now buried facets acting as the weakness. They averaged about a foot deep and ranged from 30 to 100 feet wide. (Check Current Conditions in the upper menu for more details on each of these)


      Over the next 24 hours.

Recently wind loaded slopes are the main focus today in the backcountry. Mid and upper elevation slopes, especially near ridgelines with an easterly component are the most likely spots to trigger an avalanche. Watch for snow that has a "thicker" feel to it. An increase in hand hardness from the underlying faceted snow to the newest snow is the poor structure you want to avoid.


      Over the next 24 hours.

With a plethora of weak snow around, I can't rule out the possibility of triggering something into older faceted snow. It seems like you have to hunt around to find a slab that will fail but again, it's not hard to find areas with lots of week underlying snow. Continue to pay attention to any collapsing or "whoomping" noises indicating a failure of these weak grains.


We'll see partly cloudy skies today with ridgetop highs around 20. Ridgetop winds will be light or may bump in speed slightly from the northwest. We should see partly cloudy skies over the next couple of days with a slight overall increase in temperatures. A minor disturbance is showing up in the models around mid week but doesn't look like it will produce much snow as of now.
