Good morning, this is Drew Hardesty with the
We’re in a bit of a holding pattern, waiting for tonight when the meat of the next Pacific storm rolls through. Skies are overcast with a few random flakes falling here and there, and temperatures continue their upward march into the low to mid-20’s. The west and northwest winds averaged 20-35mph with the most exposed anemometers humming along at 40-45mph. They’ve since calmed somewhat, but should remain in the 15-25mph range until, as the Tappet brothers say, ‘the third half of the show’, when they push back into the strong range. Backcountry conditions are best on a wide platform but tricky with the wind’s constant hammering.
Many ski area control teams needed a pry bar to
dislodge the stubborn new wind drifts yesterday, but found them running fast
and far on the old bed surfaces once in motion. The most interesting control work came from
Stubborn wind drifts may still be triggered on steep lee slopes at the mid and upper elevations, potentially breaking out a few turns into the slope, or a few dozen feet above you. For the upper snowpack weaknesses, collapsing will give some indication here as well, as will more dedicated snow-pit tests. These weak layers have been found on a variety of aspects and elevations and seem patchy in the Cottonwoods and more pronounced in the other outlying areas. Avalanches failing on these layers may pull out above you or at a distance, and may trigger other slides. Insult to injury here is that many of them are sitting on a perfect bed surface of old wind and suncrusts. The bottom line before the bottom line is that conditions will be quite varied and tricky today, and you’ll want to be on your game.
Steep wind drifted slopes at the mid and upper elevations will have a MODERATE danger today. Human triggered avalanches will be possible while natural or spontaneous avalanches are not expected. Folks who have been riding “everything that’s white” will want to take a step back now that we have a buried weak layer in the upper portion of the pack.
We’ll have overcast skies and intermittent snow showers until the storm arrives this evening. Winds will back to the southwest today and gradually increase to 20-30mph by about dinner time. 8000’ highs will each into the low thirties as 10,000’ temps continue reaching into the mid-to upper twenties. Snow totals through midday Tuesday look to be about 6-12”, depending on location. Another windy storm arrives Wednesday with another good shot slated for the weekend.
