current conditions

Snow surface conditions remain quite variable across the Logan area mountains. Rain crusts, wind buff, corn snow, punchy slabs, pockets of soft snow - you name it, we've got it. Moving around on skis is like playing roulette, you just never know what you're going to get until you're right on top of it. Sledding is decent on the roads and well-traveled paths but becomes a bit challenging once you head off trail.

  • The Tony Grove Snotel at 8400' reports 22°F, and there's 55 inches of total snow at the site containing 83% of normal SWE (or Snow Water Equivalent).
  • It's 23°F at the UDOT Hwy 89 Logan Summit sheds, and a north wind is blowing 5 to 10 mph.

High elevation terrain looks pretty well covered though trailhead access across the zone is thin and icy.

recent activity

No avalanches have been reported recently in the Logan zone.

  • A party triggered a large collapse Saturday on a northeast facing slope at around 8000' in outlying terrain above Bear Lake, indicating that areas with unstable snow still exist in places.
  • Skiers report cracking out a few shallow but sensitive wind slabs in the Garden City Bowls area on Sunday.

over the next 24 hours

Despite strong winds in the forecast, with little to no snow available for transport, we'll likely not see wind slabs form until it actually starts snowing tonight.

Continue to practice safe travel protocols by exposing only one person at a time when moving through avalanche terrain. Widespread buried faceted layers appear dormant for now, but if you trigger an avalanche running on old snow it could be dangerous. Continue to avoid very steep rocky slopes with shallow snow and poor snow structure.

Widespread buried faceted snow exists across the Logan Zone. This is very weak snow, but the suspect weak layers appear dormant currently under a hardening slab. The snow is generally stable in most areas.


Snow is on the way! A storm is set to move into the Logan zone tonight preceded by strong southwest winds today. Wind speeds will increase throughout the day with gusts nearing 40 mph along ridgelines. Strong winds are expected to continue through the night. If the stars align, we could get 2-4" overnight and 1-3" tomorrow - a nice refresher for our tired snowpack. Keep your fingers crossed! Stormy weather continues through Thursday evening when the system clears out and leaves behind cold temperatures in its wake.

Today: A 30 percent chance of snow after 11am. Mostly cloudy, with a high near 30. Breezy, with a southwest wind 18 to 26 mph, with gusts as high as 40 mph. Total daytime snow accumulation of less than one inch possible.
Tonight: Snow likely. Cloudy, with a low around 12. Wind chill values as low as -1. Breezy, with a west wind 22 to 26 mph, with gusts as high as 40 mph. Chance of precipitation is 70%. New snow accumulation of 2 to 4 inches possible.
Thursday: A 50 percent chance of snow. Mostly cloudy, with a high near 20. Wind chill values as low as -8. Breezy, with a west northwest wind 22 to 24 mph, with gusts as high as 38 mph. New snow accumulation of 1 to 3 inches possible.
Thursday Night: A 20 percent chance of snow before 11pm. Partly cloudy, with a low around 8. Wind chill values as low as -4. Northwest wind 7 to 15 mph.
