Avalanche Advisory
Advisory: Logan Area Mountains Issued by Paige Pagnucco for Monday - April 2, 2018 - 6:14am
bottom line

The avalanche danger is LOW with generally safe avalanche conditions. Avoid steep slopes with freshly wind-drifted snow. Be aware of changing weather conditions and adapt your travel plan accordingly.


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




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

Conditions run the gamut from softer snow at lower and mid elevations to wind buffed and firm surfaces up higher. Riding conditions are supportable though access is melting out at Tony Grove, Franklin Basin and Beaver Creek.

  • The Logan Peak weather station reports 32 F.
  • The UDOT weather station at Hwy 89 Logan Summit reports 39°F, with west northwest winds blowing 20-25 mph with gusts in the 30's.

My pit yesterday (observation) was almost completely isothermal - each layer was the same temperature. Although a great sign for overall stability, the moist, weak facets near the ground are still a concern. In the case of either many warm nights in a row or heavy rain, this old, weak layer about 45 cm off the ground just might re-activate.

recent activity

An observer noted significant wet avalanche activity in the Pine Canyon area of the Wellsvilles yesterday. He noted several natural slides and was able as well to trigger several himself. Some of these ran hundreds of vertical feet and piled up quite deeply.

I observed some small, loose wet avalanches on an east facing 8900' slope yesterday in the Steam Mill Peak area.

description

What a difference a day makes - yesterday's sunshine and warmth gives way today to cold and windy winter-like conditions. Mountain temperatures will plummet into the teens F by afternoon (but it will feel closer to 0 F with the added wind chill) locking up the weekends warm snowpack. A few things to keep in mind if you're headed into the backcountry:

1. Strong westerly winds may create small wind slabs in exposed upper elevation lee terrain. Avoid steep slopes with freshly wind-drifted snow.
2. Firm conditions on steep slopes offer slide-for-life conditions - avoid high consequence terrain to minimize your exposure.
3. 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 cornices as they can break back further than you expect
