Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Saturday morning, April 27, 2019
We're no longer issuing danger ratings this spring, but avalanches will still happen in the backcountry.
This weekend (4/27/19): Upper elevation temperatures below freezing and clear skies overnight are good for stability. Wet avalanches are generally unlikely in the morning, but will become possible in steep terrain as snow softens with daytime heating.
  • Get an early start and head home early.
  • Evaluate snow and terrain carefully.

Special Announcements
Thank you to everyone! The Utah Avalanche Center could not exist without your support.
Weather and Snow
Weak high pressure will build across northern Utah today. A relatively dry cold front will push into Utah on Sunday. Unsettled weather is then expected through the first half of the week.
Coverage in the backcountry is quite good for late April, with 6 feet of total snow still at the 8400' Tony Grove Snotel. Temperatures dropped just below freezing overnight and skies cleared, so you'll likely find solid, smooth, and gradually softening springtime snow conditions this morning, and on similar mornings heading into May...
Recent Avalanches
Numerous fairly large natural wet loose and a few wet slab avalanches occurred in April across the Logan Zone.
Avalanche Problem #1
Wet Snow

Size
Description
Get an early start and head home early. Reevaluate your route if you start sinking into soft wet snow.
Avoid being on or under steep slopes with melt-softened saturated snow, and stay out of runout gullies.
Avalanche Problem #2
Cornice
Type
Location
Likelihood
Size
Description
The warmth of springtime is causing large cornices to buckle and calve especially during the midday heat, and during cloudy periods when nighttime temperatures stay above freezing.
As usual, it's best to stay off and out from under large ridge top cornices, which are likely to break further back than expected, and could trigger avalanches on steep slopes below.
