Avalanche Advisory
Advisory: Provo Area Mountains Issued by Evelyn Lees for Saturday - January 31, 2015 - 7:03am
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 sensitive on shady, northwest, north and northeasterly facing slopes. A MODERATE danger may also develop for triggering damp, loose sluffs as the day heats up. 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.




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 our Advanced 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.

RESEARCH PROJECT ON UNDERSTANDING TRAVEL BEHAVIOR IN AVALANCHE TERRAIN NEEDS YOU!
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

A few final snowflakes are drifting down this morning, as skies clear from the north. The Park City and Provo area mountains received 2 to 3 inches of snow from the southeasterly flow, with only a trace to an inch recorded elsewhere. Temperatures are in the 20s this morning, and the winds very light from an easterly direction.

There is not much soft snow left between the old tracks, sun and wind crusts, and what there is will be found on shady slopes above about 9,000’. The crusts will be slow to soften today, so there is some “slide for life” potential on steep, icy slopes.

recent activity

No avalanches were reported from the backcountry yesterday.

Overnight, there were some moderate southeasterly winds speeds, and this morning, winds will be shifting to the northeast and again increasing in speed. There is just enough loose snow to blow and drift, especially along the Park City ridge line and in the Provo area mountains. The new drifts will be found on a variety of aspects, and be 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.

The ability of the steep continuous terrain in the Provo area mountains to produce long running sluffs with very little snow never ceases to amaze me. If the sun comes out as forecast, be alert for the newest few inches of snow to become damp, and for it to be possible to trigger sluffs.

weather

The “storm” will quickly depart this morning, with mostly clear skies by this afternoon. 10,000’ highs today will be in the twenties, with 8,000’ temperatures warming into the mid to upper 30s. The northeasterly winds will increase this morning, into the 10 to 20 mph range, with the higher ridge lines averaging to 25 mph, with gusts in the 30s. Mostly clear skies tonight and tomorrow, as high pressure once again takes control.

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.
