Avalanche Advisory
Advisory: Logan Area Mountains Issued by Paige Pagnucco for Saturday - March 31, 2018 - 6:11am
bottom line

The avalanche danger is low this morning but may rise to MODERATE with daytime heating. Wet avalanches will be possible in the heat of the day.

  • Practice safe travel protocols and carry avalanche rescue equipment.
  • Avoid treacherous ridge top cornices and slopes with saturated snow.

I will update this advisory by 7:30 Monday morning, 4/2/18.




special announcement

The newest issue of the Powder Cloud, the newsletter of the Utah Avalanche Center is hot off the presses. You can always grab a cup of coffee and while away the time by looking at new and old issues of the Powder Cloud, other essays, and blogs. Look for them in the menu above or click here.

The UAC Marketplace is still open. Our online marketplace still has deals on skis, packs, airbag packs, beacons, snowshoes, soft goods and much more.

current conditions

Due to sunshine and warm temperatures, last weeks powder snow is all but gone except on sheltered, shaded, due north high elevation slopes. You'll find supportable conditions across the zone though triggered cornice falls are still possible today and warming temperatures will create a rising danger of wet avalanches.

  • The Tony Grove Snotel at 8400' reports 36°F, and there's 69 inches of total snow, with 83% of normal SWE.
  • The UDOT weather station at Hwy 89 Logan Summit reports 39°F, with west northwest winds blowing 10-20 mph.

There have been no avalanches reported recently.

Mountain temperatures last night did not get below freezing which, at this time of year, is critical to solidifying the snowpack. Moderate westerly winds and cloud cover should help keep wet activity somewhat in check today BUT, as is typical with springtime conditions, the danger of loose wet avalanches, wet slabs, and triggered push-alanches will rise as temperatures warm. When the snow becomes saturated and/or you start seeing signs of instability like rollerballs, it is time to find lower angle and/or shadier terrain.

Remember that risk is inherent in mountain travel:

  • Always carry avalanche rescue equipment
  • Practice safe travel protocols by only exposing one person at a time
  • Be mindful of changing conditions throughout the day and adjust your travel plan accordingly
  • Stay well back from the edge of sagging cornices as they can break back further than you expect

Though this skier-triggered cornice break is near Jackson, WY, it clearly demonstrates the harsh consequences of getting too close to the edge. (The unlucky skier fell 1000' vertical and remains in critical condition.)

weather

It'll be a bit warmer today in the mountains with temps nearing 42 F. A small disturbance will pass through bringing with it cloud cover, moderate westerly winds, and a small chance for snow. Little accumulation is expected. Sunday looks to be sunny, warm, and windy as another small system moves into the area on Sunday night/Monday with slightly cooler temps, strong winds, and a chance for a few inches of snow.

Today: A 20 percent chance of snow showers. Mostly cloudy, with a high near 42. West wind 14 to 21 mph.
Tonight: A 30 percent chance of snow showers, mainly before midnight. Mostly cloudy, with a low around 27. West northwest wind around 17 mph. New snow accumulation of less than one inch possible.
Sunday: Mostly sunny, with a high near 42. Breezy, with a west northwest wind 15 to 22 mph.
Sunday Night: A 20 percent chance of snow showers after midnight. Mostly cloudy, with a low around 32. Breezy, with a west southwest wind 22 to 25 mph, with gusts as high as 39 mph.
Monday: A 50 percent chance of snow showers. Cloudy, with a high near 37. Windy, with a west wind 25 to 30 mph, with gusts as high as 44 mph. New snow accumulation of 1 to 3 inches possible.
