Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - February 27, 2015 - 6:54am
bottom line

You'll find nice shallow powder and dust-on-crust at upper elevations, stable snow conditions, and a LOW (Level 1) avalanche danger in the backcountry. Perhaps of more concern than avalanches is potential for sliding falls and loss of control on slick, rock-hard snow at lower elevations and underlying a dusting of light powder on many slopes up higher.

  • Use normal caution
  • Stay in the habit of using safe travel protocols
  • Practice companion rescue with your riding partners

current conditions

The Tony Grove Snotel reports a couple inches of very light new snow in the last 24 hours. There's 69 inches of total snow containing 94% of average water for the date, and it's 16 degrees at 8400'. The UDOT Hwy 89 Logan Summit weather station also reports a little light new snow, 10 degrees, and light easterly winds overnight. There's some nice shallow powder in sheltered north facing terrain, but it's more dust-on-crust in most places. The snow is rock hard and slick at lower elevations and also on many slopes where the recent snow has been scoured off by winds. Don't be fooled by a couple inches of powder, backcountry riders risk sliding falls and loss of control in these conditions, and I'd recommend using an ice-ax and crampons on many mountain ascents this weekend.

Even just a little bit of snow helps. Sun and snow made for fine shallow powder conditions in White Pine Canyon yesterday. 2-26-2015

recent activity

No avalanches were reported locally since the first week of February, but I've noticed some small natural wind slabs at upper elevations and wet sluffs on sunny slopes that are more recent.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

Although unlikely, triggered wind slab avalanches are possible in some drifted upper elevation terrain. Avoid stiffer, wind deposited snow on the lee side of ridges, in and around terrain features like gullies and cliff bands, and areas where snow is vertically cross-loaded near sub-ridges, roll-overs, or scoops lower on the slope.


It'll be mostly cloudy today, with moderate north winds, a high around 25 degrees, and a 40% chance of a little snow. The weather pattern looks active, heading into the weekend, but most of the energy looks to be heading south.... Better potential exists for significant snow in our neck of the woods early next week.
