Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Bruce Tremper for Sunday - February 1, 2015 - 7:34am
bottom line

The avalanche danger is MODERATE on steep, wind drifted upper elevation slopes. While the drifts can be found on all aspects, they will be most widespread on northeast, east and southeasterly facing slopes.. Even a small slide can have serious consequences in radical terrain, if it takes you for a long ride or through rocks, trees and cliffs. If the snow starts toi heating where you are, and damp sluffs become possible, move to lower angle terrain or to a cooler aspect..

special announcement

Learning about snow and avalanches never ends. The more you learn, the more you realize there is to learn. We still have space in ourAdvanced Avalanche Skills Workshop with Bruce Tremper on February 5th (evening) and 7th (on snow around the Brighton perimeter) and the Snowbasin Freeride Avalanche Summit, organized by Craig Gordon, the afternoon of February 7, followed by 2 days on snow – February 8th and 9th. Find them listed on our education page.

Scientists from the Snow and Avalanche Lab at Montana State University are seeking more participants for their project examining decision making and travel in avalanche terrain. Their project aims to collect GPS location information (from your smartphone) and survey responses from backcountry skiers and riders to better understand what types of terrain are used and how decisions are made. Their focus is on backcountry skiers and riders of all abilities and experience.

current conditions

With high pressure in control, skies are clear this morning and temperatures have dropped. Most stations are in the low 20s and teens, with a few single digits in the canyon bottoms. The northwesterly winds kicked in, with mostly moderate speeds - 15 to 20 mph averages. But the high peaks have averaged to 40 mph, with gusts in the 60s.

recent activity

Yesterdays avalanche activity involved a few small wet loose sluffs on steep sunny slopes and some shallow wind drifts that were mostly unreactive.

over the next 24 hours

Overnight, the winds picked up from the northwest, and do have some snow available to blow and drift. The new drifts will be found on a variety of aspects, not just easterly, as the winds are channeled and swirled by the terrain. However, I would expect them to be most widespread on upper elevation east and southeasterly facing slopes, and most sensitive on the more northerly facing slopes, where they will be sitting on weaker faceted old snow. Dense slabby snow or cracking are indications you’ve found a sensitive wind drift.

Out of the wind affect terrain, small sluffs could be triggered on steep, upper elevation shady slopes, and damp sluffs may become possible as the day heats up. Afternoon clouds should keep the snow from becoming to damp.


High pressure will start the day with clear, sunny skies, though moisture and cloud cover will begin increasing from the northwest this afternoon. Temperatures will warm into the the mid 30s at 8,000' and into the upper twenties at 10,000'. Winds will remain elevated today, and shift to a more westerly direction. A moist west-northwesterly flow will stay over northern Utah for the first half of the week, with periods of light snowfall possible starting tonight. Winds speeds will increase again slightly overnight.

general announcements

Remember your information can save lives. If you see anything we should know about, please participate in the creation of our own community avalanche advisory by submitting snow and avalanche conditions. You can also call us at 801-524-5304, email by clicking HERE, or include #utavy in your tweet or Instagram.

If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
