Avalanche Advisory
Advisory: Salt Lake Area Mountains Issued by Brett Kobernik for Sunday - March 1, 2015 - 6:29am
bottom line

The majority of the terrain has a LOW avalanche danger today. There is a "pockety" MODERATE avalanche danger on steep upper elevation terrain where yesterday's winds created fresh drifts. These drifts are on a variety of aspects and crossloaded terrain features. Keep in mind the wind was from the southeast which loaded west facing slopes, something that we don't always see that often.

current conditions

Snowfall picked up Saturday afternoon especially on the Park City side of the range which was favored orographically by the southeast wind direction. Totals from the last 24 hours are 4 inches in the upper Cottonwoods and around 7 inches along the Park City ridgeline. The southeast winds picked up yesterday morning and died down in the afternoon. They were light and variable overnight but mostly had a southwest direction. Overnight ridgetop temperatures were in the mid to upper teens and we have cloudy skies this morning.

On a side note, yesterday's 4 inches put total snowfall for February at the Alta Guard at 35 inches. The record for the lowest amount recorded in February was in 1950 with 34 inches. We almost did it this year, just like the Seahawks. Year to date snowfall at the Alta Guard is 196 inches.

recent activity
Like clockwork with the dang east winds yesterday, I put out the forecast anticipating (hoping) they would stay in check but instead they immediately picked up (just after publishing the forecast) and started drifting snow. Then the calls started coming in about people triggering these fresh drifts. This is not what a forecaster wants after issuing a LOW danger. A number of them were triggered and were mostly in the 6 to 12" deep range but one in Banana Days was reported as up to 18" deep. Most of these were on northeast facing slopes. They ate themselves up once they ran down the slope a distance.

description

If you are getting into higher terrain you will again want to watch for the fresh slabs which formed on Saturday. They will not be as sensitive but I'm almost positive someone will get one to release today. The threat for burial is not the main concern with these but rather sustaining an injury if you were to get pushed around or dragged over exposed terrain with rocks and trees. If you are aware of this situation and act accordingly, you'll have no problem out there today. It should be noted that a number of the favorite west facing chutes will have wind loaded starting zones. I'm thinking of west facing chutes along the Reed and Benson ridgeline, chutes into Mineral Fork from Cardiff Fork, chutes along Kessler, etc.

Slope cuts are appropriate for this situation as long as no one is below. This was demonstrated nicely in this observation from Banana Days. Thanks Kyle Cummings!

weather

We'll see clouds and the slight chance for flurries today. We could see some breaks in the clouds as well mid day. Ridgetop temperatures will get into the low 20s and southwest winds will be light to moderate in speed. Snowfall picks up again tonight into Monday in a southerly flow with slightly warmer temperatures. The last piece of the storm drifts through from the northwest Monday night into mid day Tuesday with colder temperatures again. We could see another 10 inches of snow or better by the time it's all said and done.
