Forecast for the Logan Area Mountains

  • Avoid steep slopes with saturated surface snow.
  • Stay off and out from under ridge-top cornices.
  • Evaluate snow and terrain carefully.

Weather and Snow

You still might find some nice powder riding and skiing in sheltered, north facing terrain at upper elevations. Despite today's cloud cover, seasonal warmth will cause potential for loose wet avalanches entraining saturated snow.

  • The Tony Grove Snotel at 8400' reports 30°F, and there is 75" of total snow with 96% of average SWE.
  • The UDOT ​Hwy 89 Logan Summit weather station reports 24°F, and calm conditions.


There is still plenty of snow up high, but getting there is an issue. Please do your best to limit resource damage. Stay on roads and avoid riding over bare ground, melted out meadows, and sage brush. It is possible to bring your trailer up the Tony Grove Road to the first overlook where you can park close to the retreating snow. There is still snow at the Beaver Creek and Sinks Winter THs...

Recent Avalanches

Riders intentionally triggered a handful of small wind or storm slabs Friday in the Tony Grove Area. The new snow was not bonding too well to the underlying old snow, especially in drifted terrain and on very steep slopes. The storm snow is rapidly stabilizing this weekend, and wind slab avalanches are unlikely today, yet still a possibility.

Wet Snow
Type
Location
Likelihood
Size
Description

Seasonal warmth will cause heightened wet avalanche conditions in steep terrain. Natural and triggered loose wet avalanches (or sluffs) entraining saturated surface snow are possible and most likely during the heat of the day.

  • Roller balls, pin-wheels and natural sluffs in steep terrain indicate potential for loose wet avalanches.
  • Loose wet avalanches entraining moist or saturated surface snow could become large and unmanageable on long sustained slopes.
  • Avoid being on or under steep slopes with saturated surface snow.


Watching the Folly in Logan Dry from town. In the first picture from Friday evening 4/13, there is a bit of wet surface activity visible on sunny mid elevation slopes. More activity is visible in the second, from around 7:30 pm yesterday, Saturday 4/14.

Avalanche Problem #2
Normal Caution
Type
Location
Likelihood
Size
Description

Use normal caution while traveling in the backcountry. Remember, all members of your party need to carry and practice with beacon, probe, and shovel. Continue to cross steep slopes and potential avalanche paths one-at-a-time, while the rest of the party watches from a safer place.

  • Watch for and avoid drifted snow on the lee side of major ridges and in and around terrain features like gullies, scoops, sub-ridges, and rock outcrops.
  • Avoid and stay out from under overhanging cornices, which might break further back than expected and could trigger avalanches on steep slopes below.
Additional Information

A spring storm will impact the region early in the week. The associated cold front will reach northwest Utah late tonight, then track across the area late Monday through early Tuesday. High pressure will return midweek, followed by the next storm system late in the week.

  • Today: Mostly cloudy, with a high near 43. South southwest wind 11 to 17 mph.
  • Tonight: Partly cloudy, with a low around 35. Windy, with a south wind 21 to 26 mph increasing to 29 to 34 mph after midnight. Winds could gust as high as 48 mph.
  • Monday: A 50 percent chance of snow showers. Mostly cloudy, with a high near 42. Windy, with a west southwest wind 35 to 40 mph decreasing to 25 to 30 mph in the afternoon. Winds could gust as high as 55 mph. New snow accumulation of less than one inch possible.
