current conditions

The Tony Grove Snotel at 8400' reports 28°F and 27" of total snow containing 92% of average SWE (Snow Water Equivalent). It's 22°F at the 9700' CSI Logan Peak weather station, with west wind currently blowing around 25 mph. Snow surface conditions are quite variable, with wind damage up high and a crust on sunny slopes.

  • There is more total snow and better coverage in the central and northern Bear River Range and at upper elevations.
  • 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.

Weak surface snow develops during periods of high pressure. Feathery surface hoar is actually frost growing on the snow surface (12-14-17).

recent activity

No new avalanches were reported in the past week. A natural avalanche cycle occurred at upper elevations during the intense storm on 12/3/17.

type aspect/elevation characteristics
over the next 24 hours

The air is clean in the mountains, temperatures are warm, backcountry snow is mostly stable, and travel is fairly easy on supportable snow. The avalanche danger is Low, which means that avalanches are unlikely. Even so, avalanches are still possible, especially in very steep or extreme terrain.

  • Wind slab avalanches are possible on some drifted upper elevation slopes. Avoid drifts in steep terrain near ridges and in and around terrain features like gullies, saddles, rock bands, scoops, and sub-ridges.
  • A ride in even a small avalanche could be particularly dangerous due to the hard underlying snow and potential for being raked through rocks or deadfall below.

High pressure will reside across the area today. A splitting Pacific system will cross the area Saturday. High pressure will build into the area once again Sunday into Tuesday, with another storm expected Wednesday.

  • Today will be sunny, with a high temperature at 8500' around 36°F and 10 to 15 mph west wind.
  • Tonight will be mostly cloudy with a low around 20°F and 15 mph west wind. There is a 30% chance of snow after 11:00 pm, with less than an inch possible.
  • Saturday: Snow. 8500' temperatures will drop to around 19°F by evening, and northwest winds around 11 mph are expected. 1 to 3 inches of snow is possible.
general announcements

With rather meager snow conditions and nice weather in the mountains, now is a great time to practice companion rescue techniques with your backcountry partners.
