Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Brett Kobernik for Wednesday - February 12, 2014 - 7:19am
bottom line

DANGEROUS AVALANCHE CONDITIONS REMAIN!! The avalanche danger will again be on the rise over the next couple of days. Human triggered avalanches are likely on many slopes and almost certain on steep upper elevation north through east facing slopes. The overall avalanche danger is CONSIDERABLE but areas of HIGH DANGER remain. Those without expert level avalanche skills are urged to avoid going into the mountains at this time.




avalanche watch

DEEP, DANGEROUS AND POTENTIALLY UNSURVIVABLE AVALANCHES ARE STILL BEING TRIGGERED BY PEOPLE AND THE DANGER WILL INCREASE DURING AND AFTER THE UPCOMING WET AND WINDY STORM WITH RISING TEMPERATURES. PEOPLE WITHOUT EXPERT LEVEL AVALANCHE TRAINING AND EXPERIENCE SHOULD AVOID BACKCOUNTRY TRAVEL OVER THE NEXT COUPLE OF DAYS. AVOID BEING ON AND BELOW ALL STEEP SLOPES AND WATCH FOR ROOFS TO AVALANCHE AS TEMPERATURES INCREASE.

current conditions

Under partly cloudy skies temperatures are just slightly warmer this morning than they were yesterday morning. We had lows in the upper teens to around 20 degrees. Westerly winds bumped in speed slightly late yesterday afternoon but have slowed again as of now.

recent activity

There were large human triggered avalanches breaking into old preexisting weak snow in all regions from the Manti Skyline, Western Uintas through the Central Wasatch to Logan yesterday. Here in the Wasatch, two separate groups of skiers came together on a ridgeline in Mineral Fork of Big Cottonwood and the combined weight was enough to initiate a collapse and trigger a very large avalanche from a distance. They were in a safe location on a flat section of a ridge and the avalanche released and ran down a steep slope below them. DETAILS

Also, a snowboarder had a cornice collapse under him and he tumbled onto a steep slope in Dutch's Draw. Luckily, the slope he landed on did not release and produce a larger more dangerous avalanche. DETAILS

It's no time to split hairs with this avalanche threat. It is not wise to try and out smart persistent weak layers. You may not see any 'bullseye' red flags as noted in some observations. It is best to just 'chill' and let things take their course for a bit. Perhaps once this storm moves through and we go through some settlement we might see some improved stability but at this time it's unclear how this will shake out. We anticipate that the avalanche danger will increase over the next couple of days with more snow, wind and warming temperatures.

Avoid areas with both old and new wind slabs. These on their own may be sensitive but in many areas they will just compound the danger of the buried persistent weak layers by continuing to add more weight on top of the already poor snowpack structure. It's not the time to attempt to use mitigation techniques such as ski cuts. Even using small test slopes by sidehilling a snowmobile or jumping on them with snowshoes is not recommended right now unless they are the smallest and most benign slopes with no consequences if they avalanche.

weather

We should see snow start later this afternoon with 2 to 4 inches of accumulation possible by this evening. Snow densities should be moderate to high. Temperatures will warm to near freezing at 8000 feet and into the mid 20s along the ridges. Rain/snow line should be around 7000 feet. Stiff westerly winds will increase during the day. Stiff westerly winds and periods of snow should continue tonight through Thursday with perhaps around a foot of snow total and around an inch of water give or take. 700mb temps go to +3C by Saturday. What this means is VERY warm temperatures as we move into the weekend.

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 or 800-662-4140, 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.
