Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Monday - April 3, 2017 - 6:42am
bottom line

Backcountry snow is generally stable, and the avalanche danger is LOW. Even so, 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

The Tony Grove Snotel ​reports 20 °F and 2" of new snow in the past 24 hrs. There's 104" of total snow, with 144% of average SWE (Snow Water Equivalent)​ at 8400'. A 12 mph west wind is blowing at the CSI Logan Peak weather station and it's 12 °F. Last night was clear and cold, and fine spring conditions exist in the backcountry. Solid snow, capped by creamy powder at upper elevations, is smooth and stable. Triggered shallow wind slabs are possible near ridge-lines this morning, and seasonally warm daytime temperatures will create wet avalanche potential on steep sunny slopes.

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.

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.
