current conditions

The Tony Grove Snotel at 8400' reported 4" of new snow Tuesday morning, but it seemed like less with only 0.3" SWE (Snow Water Equivalent). Yesterday evening there was 19" of total snow containing 111% of average SWE. It's 29°F at UDOT Hwy 89 Logan Summit this morning and there's a stout west wind currently averaging 15 mph with gusts to around 30 mph.

Record warmth around Thanksgiving melted a good deal of snow across the zone, and with a solid refreeze, it turned the remaining snow rock hard. We found a couple inches of new snow and smooth dust-on-crust conditions near Tony Grove Lake yesterday. Shallow, early season snow conditions exist, and hitting rocks or stumps is a significant hazard. Travel cautiously and keep your speed down. The Tony Grove Road is not maintained for wheeled travel in the winter.
recent activity

We noticed piles of wet debris is West Miller Bowl from loose wet sluffs that occurred during the record warmth last week.

description

Shallow wind slabs consisting of fresh snow may exist on some upper elevation slopes, and these should be easy to identify and avoid. The rock solid refrozen November snow under the dusting is stable, and avalanches are unlikely. A ride in even a small avalanche could be particularly dangerous due to potential for being raked through rocks or deadfall below. Avoid very steep terrain or use an ice ax to reduce the hazard of uncontrolled slides or falls on steep slopes with slick hard snow.

weather

A fast moving weather disturbance will clip the Logan Zone today, with another weak system grazing the north Friday. A colder system will settle across the region Sunday into Monday. Snow showers are possible this morning with a high temperature at 8500' around 30°F​, and breezy conditions in the mountains, with northwest winds 10 to 20 mph. Low temperatures around 20°F are expected tonight, with mostly clear skies and 6 to 8 mph west winds. Tomorrow will be mostly sunny, with high temperatures near 34°F​ and 7 to 9 mph southwest wind.
