Good morning, this is Evelyn Lees with the
Under partly cloudy skies, temperatures remain stuck in the single digits once again this morning, though at least they’re on the plus side of zero. Winds have been blowing anywhere from the southwest to northwest over the past 12 hours, with speeds of 25 to 35 mph across the highest terrain, and gusts to 50. Off the higher ridgelines, average speeds have been 10 to 15 mph. Cold, lazy flakes have been falling on and off for the past 5 days, and have added up to 10 to 12 inches in the Cottonwoods and 3 to 6” in the Park City and Ogden area mountains. Turning conditions are good in light powder on most aspects and elevations, with some wind damage in open terrain.
Most of yesterday’s reported avalanche activity was loose sluffing of surface snow on steep slopes of all elevations. The odd soft and hard wind drifts were also encountered, though most were shallow, small and not reactive.
Today’s avalanche concerns include sluffing of the surface snow on steep slopes of all aspects and elevation. These sluffs are running fast and far in continuously steep terrain, and they are large enough to knock you off your feet or over a cliff. Also, avoid any fresh drifts of wind blown snow that may have formed yesterday afternoon and overnight at the higher elevations. These are also large enough to take a person for a ride.
With a storm approaching, observe the upper layers of the snowpack – there is a mix of near surface facets, weak low density snow and localized slopes with sun, rime and rain crusts buried up to 1/2 meter deep, which could produce an interesting avalanche pattern when loaded.
Bottom Line for the
There are pockets of MODERATE avalanche danger on steep slopes with recent drifts of wind blown snow and on steep slopes for fast moving sluffs that are now large enough to knock you off your feet. Out of the wind affected terrain and on slopes less steep than about 35 degrees, the avalanche danger is generally LOW. Notes: If you are heading out on a more remote adventure this weekend, the avalanche danger is probably a notch higher in the outlying areas we don’t forecast for and terrain above about 11,000’ in general. Also, with snow in the forecast, there will be an increasing avalanche danger late Sunday into Monday.
This morning’s clouds
should break up about midday, and temperatures warm as the winds shift to the
west ahead of the next storm. 8,000’
highs will feel balmy as they approach 30 degrees today, and 10,000’
temperatures will be inching towards 20.
The northwest to westerly winds will be in the 5 to 15 mph range at most
elevations, and the gusty upper elevation winds should gradually decrease. A
rather complicated storm will bring snow starting midday tomorrow, with the heaviest
snow Sunday night into midday Monday. Cold
temperatures will follow the storm, with highs dropping back down into the single
digits for most of next week.
Wasatch Powderbird Guides did not fly on Friday due to weather, and if the weather allows today they will be in Mineral,
On Thursday, January 24th, there will be a panel discussion on risk and decision making in outdoor activities, which should be very interesting. It will be at the Salt Lake Downtown Library at 7:00 pm and it will also be broadcast on KCPW.
The second annual avalanche awareness snowmobile ride is Saturday, February 2nd and proceeds will help support snowmobile specific avalanche awareness projects. Detains can be found at http://www.avarides.com/
The free avalanche beacon parks are up and running at Solitude,
Snowbird and the Canyons. They’re great
places to practice alone or with friends.
