Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Tuesday morning, April 2, 2024
Heightened avalanche conditions exist in the backcountry, and the danger is MODERATE. Although becoming less likely, people could still trigger soft wind slab avalanches 1 to 2 feet thick in drifted upper-elevation terrain. Sunny skies and warming temperatures today will elevate the potential for wet avalanches on slopes at all elevations steeper than 30°.
Evaluate the snow and terrain carefully. Avoid being on or under slopes with melt-softened saturated snow, and stay out from under large overhanging cornices that may fail in the heat of the day.

Weather and Snow
We found generally stable snow and pretty good powder riding conditions in upper-elevation shady terrain yesterday, but heightened avalanche conditions exist, particularly in drifted terrain. New snow and wind slab avalanche conditions generally stabilize fairly quickly, and we do not see any problems with buried persistent weak layers in the Logan Zone. A significant issue again today will be solar heating, seasonal warmth, and the increasing potential for wet avalanches, entraining heavy piles of moist or saturated snow.
The Tony Grove Lake Snotel at 8400' reports 26° F this morning, and there is 106 inches of total snow at the site containing 125% of normal snow water equivalent.
At the 9700' CSI Logan Peak weather station, winds are blowing from the north 18 mph with gusts in the mid 30s, and it's 23° F.
At our new Paris Peak weather station at 9500', it's 23 °F, and the wind blows from the north-northeast 13 mph.
It's 24° F at our new Card Canyon weather station at 8800' and there is 93 inches of total snow.
Expect increasingly warm temperatures and sunny conditions in the mountains for the next few days. Snow showers are likely at the end of the week and it looks like another winter storm for the weekend.. For more information, visit our mountain weather page HERE
Recent Avalanches
Over the weekend, there were several human-triggered avalanches and a few close calls in the Wasatch Range. Visit our Avalanche Page for more details.
No avalanche incidents were reported over the weekend in the Logan Zone, but riders triggered numerous small slides in steep terrain.
Yesterday afternoon, we could see a large pile of fresh wet avalanche debris on a southeast-facing facet of the Beirdneau Ridge far above Logan Canyon. There were a few small natural wet slab avalanches and extensive cracking on the east side of the Logan River downstream of the Forestry Camp. report

Avalanche Problem #1
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
You could trigger soft slab avalanches of drifted snow, especially in northerly and easterly-facing upper-elevation terrain on slopes steeper than 30°. Avalanches could fail on the interface on top of last week's melt-freeze crust or a density change within the newer snow.
  • Avoid travel on wind-loaded slopes capped by large cornices on the lee side of major ridges.
  • Watch for stiffer drifted snow or wind slabs in and around terrain features like sub ridges, gully walls, mid-slope rollovers, scoops, and cliff bands.
  • Practice safe travel protocols to avoid exposing more than one person to avalanche danger.
Avalanche Problem #2
Wet Snow
Type
Location
Likelihood
Size
Description
Intense sun will cause the risk of wet avalanches to increase rapidly today. Solar heating and seasonal warmth will cause the snow to be soft and saturated throughout and prone to producing wet avalanches. Despite being rather slow-moving compared to dry avalanches, these could entrain large piles of heavy snow and grow to become large and dangerous avalanches on sustained slopes.
  • If you are sinking deeply into wet/moist snow, move to a lower-angle slope or cooler aspect or elevation.
  • Avoid being on or under steep slopes with moist or saturated snow. Collapsing or whumpfs and shooting cracks are red flags indicating unstable snow.
  • Be aware of terrain traps below like trees, gullies, sinks, or rock outcroppings that wet avalanches could sweep you into.
Additional Information
Small wet slab avalanches and extensive cracking were apparent on the banks of the Logan River yesterday. These red flags indicate the potential for wet avalanche activity on steep lower-elevation slopes.
