Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Wednesday - April 5, 2017 - 6:24am
bottom line

Backcountry snow is stable, and the avalanche danger is LOW. There is a risk of uncontrolled slides and serious falls on steep slopes with slick, rock-hard snow. Shallow triggered wind slabs are possible on drifted upper elevation slopes and wet loose avalanches will become more likely in steep sunny terrain as temperatures warm. Use normal caution.

current conditions

Last night was clear and cold, snow is stable, and fine spring conditions exist in the backcountry. The Tony Grove Snotel ​reports 22 °F and there's 103" of total snow, with 143% of average SWE (Snow Water Equivalent)​ at 8400'. A 17 mph west wind is blowing at the CSI Logan Peak weather station and it's 19 °F. Solid snow, capped by an inch or two of creamy powder at upper elevations, is smooth and stable. Snow is so hard that there's a risk of uncontrolled slides and serious falls. Some steep slopes might require crampons and an ice axe to ascend safely. Triggered shallow wind slabs are possible near ridge-lines in extreme upper elevation terrain, and warming daytime temperatures will create wet loose avalanche potential on steep sunny slopes in the next couple days.

recent activity

Other than expected wet loose activity, no backcountry avalanches were reported in the Logan Zone over the weekend.

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

Triggered shallow wind slab avalanches are possible on steep slopes in drifted terrain at upper elevations.

  • Avoid drifted snow on the lee side of ridges and in and around terrain features like gullies, scoops, sub-ridges, and cliff-bands.
  • Overhanging cornices can break further back than expected and trigger avalanches on slopes below.
  • Glide avalanches and cornice falls can occur at any time, but are most likely in the heat of the day

Avalanches entraining fresh loose wet snow are possible with midday warmth on steep sunny slopes at upper and mid elevations.

  • Watch for signs of wet instability like roller balls, pinwheels and natural sluffs under trees or rock outcroppings.
  • Avoid being on or under steep slopes if fresh snow is saturated.

Fair weather is expected in the mountains today. High pressure aloft will move west to east across the Great Basin through Thursday. Following, a series of Pacific storm systems will begin Friday, and continue into early next week. Today will be mostly sunny, with a high temperature at 8500' of 42 °F and 8 to 10 mph west southwest wind. Tonight will be mostly cloudy, low temperature of 31 °F and 8 to 11 mph south-southwest wind. Thursday will have partly sunny skies, a high temperature of 52 °F and 8 to 17 mph south-southwest wind.
