Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Tuesday - February 24, 2015 - 6:48am
bottom line

The avalanche danger is mostly LOW today, with two caveats: First, you could trigger one of the scattered small hard wind drifts, just large enough to take a person for a ride – serious in steep, rocky or treed terrain. Secondly, as the day and snow heats up, avoid the steep sunny slopes facing east through south through west, where it will be possible to trigger a wet sluff.

special announcement

The 2015 Wasatch Splitfest kicks off this Thursday night, February 26th at 7 PM, with a Presentation/Raffle night at Brewvies Cinema Pub. Come join us for a social evening of food, drinks, presentations of splitboarding adventures from around the world, and a chance to win gear from Chimera, Voile, Arc'teryx, Patagonia, and many others. All proceeds from the raffle go directly to support the Utah Avalanche Center.

The splitfest will continue through the weekend with tour meetups, clinics, demo gear, and more. This is a grassroots event to gather the backcountry snowboarding tribe, with an emphasis on safety, education, and fun. All are welcome. Check out http://www.facebook.com/WasatchSplitfest for all the details.

current conditions

It’s refreshingly cool this morning, with mountain temperatures in the teens and low 20s. The northeasterly winds have decreased, with most stations averaging in the 5 to 10 mph range. Across the highest terrain, average speeds are 15 to 20 mph.

Wind sheltered, shady slopes have some nice powder. Other aspects will be sun crusted this morning, a mix of breakable and hard and icy, though most should soften later today. Small hard wind drifts are scattered about the mid and upper elevations, ready to trip you up.

recent activity

Numerous small harder wind slabs, 2 to 10” deep and up to 30’ wide, were purposely triggered from the Mill Creek ridge line south through Little Cottonwood Canyon, with one remotely triggered. As the day heated, it was possible to push a few wet loose sluffs into motion in the Provo area mountains. No reports of new activity form the Ogden area mountians.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

There are two avalanches issue today, both of which can be mitigated by sharp observation, terrain choices and timing.

The cracky, hard wind drifts scattered about will still be sensitive today. They are just large enough to grab a person on foot, skies or a board and take them for a ride in steep terrain, while of little consequence to a snowmobiler. They are only an issue if you are caught on a slope with bad consequences where you could go for a long ride, off a cliff or into rocks. Take the time to recognize what these drifts look and feel like. They are most widespread along the ridgelines and on slopes with a westerly aspect, though I was also finding them well down into open bowls and along sub ridges.

With warmer temperatures and less wind today, wet loose sluffs will become active as the snow heats. Most will need a push, but a few naturals are possible in steepest terrain that received the most snow. Avoiding travel on and below steep sunny slopes as the snow heats up (east through south through west).

It will be another beautiful day - sunny, with temperatures warming to near 30 at 8,000’ and into the mid 20s along the highest ridgelines. The northeasterly winds will be generally light, with occasional gusts in the 30s across the highest terrain. Slightly cooler with a few scattered clouds on Wednesday and the flow turns to the northwest. The next chance for a little snow will be Thursday afternoon into Friday. The Saturday storm may head south like the last one.
