Forecast for the Salt Lake Area Mountains

Tuesday morning, March 17, 2020
Most terrain has LOW danger. Remember that LOW danger does not mean NO danger. Remember, too, that Risk is Inherent in Mountain Travel. A couple of considerations for today:
  • Pockets of Wind Slab may still be found in isolated terrain.
  • Wet avalanche activity will be possible with direct sun and daytime heating. When the snow becomes punchy and unsupportable, it's time to head home.

Special Announcements
We are sad to report that a 60-yr-old skier was killed by a large avalanche Sunday in backcountry near Pebble Creek ski resort outside of Pocatello, Idaho. This is not in our forecast zone, but we will assist in the investigation.

We know there is a lot of uncertainty regarding the Coronavirus, but the Utah Avalanche Center is planning to continue issuing regular avalanche forecasts into April.
Uphill Travel at Ski Areas - Some resorts will be offering limited uphill access but not all do. Current info about uphill access from Ski Utah is posted HERE.
Weather and Snow
Skies are partly cloudy with continued southerly winds averaging 20-25mph with gusts to 35.
Mountain temperatures are in the upper 20s up high, the low to mid-30s down low. Overnight lows were around midnight and we've been warming slowly since then.
Snow surface conditions are a mixed bag of crusts (even temperature crusts up to 9500' on northerly facing slopes) with a few patches of soft dense powder here and there. The sun crusts will soften and break down earlier today than the previous couple of days. Still, it's not really about the skiing and riding, though, is it?

For today, we'll again see increasing clouds by early afternoon and perhaps a trace of snow by dinner. Southerly winds will blow 25-30mph; temps will again rise to the mid-40s at the mid elevations. The stalled-out storm battering California with snow will soon move inland. These types of storms are fraught with uncertainty regarding trajectory and extent of precipitation; that said, we might expect 5-10" accumulating by later Friday. At least cooler air and diminishing winds arrive tonight and tomorrow.

Description
Normal Caution is advised.
  1. Pockets of both soft and hard wind slab may be found scattered across the compass, but generally on north to northeast facing slopes. I found wind drifts well off the main ridgelines Sunday, but they were not reactive. This may not be the case for lingering drifts in all areas.
  2. Loose wet sluffs are possible with direct sun and daytime highs reaching into the mid-40s; particularly in wind sheltered terrain. If you see rollerballs, pinwheels, and natural sluffs...and the snow starts to become punchy and unsupportable, move to a cooler aspect, lower angle terrain, or head to the barn.
  3. Cornices become tender this time of year, particularly with sustained winds, warm temps and direct sun. A health skepticism of the integrity of cornices is warranted.
