Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - February 20, 2015 - 7:01am
bottom line

Avalanches are unlikely, and the danger is LOW (or level 1) in the backcountry.

  • Use normal caution.
  • Watch for rocks and shallow snow conditions at mid-elevations.
  • Minimize resource damage and avoid travel over bare ground.
  • Loss of control and sliding falls are possible on smooth, solidly re-frozen snow.

current conditions

Looks like we might see a little snow in the mountains today, but there isn't much in the way of powder in the backcountry after a prolonged period of warm weather. You'll find supportable, spring-like snow on most slopes in the backcountry this morning, which will likely not soften up much due to clouds and wind today. Despite the recent mild weather, observers report finding pockets of nice re-crystallized soft snow on due north facing upper elevation slopes. An inch or two of accumulation is quite possible and will help riding conditions significantly, but even a couple inches won't be enough to increase the avalanche danger much.

The Tony Grove Snotel reports 67 inches of total snow containing 101% of average water for the date, and it's 31 degrees at the 8400' site. The UDOT Hwy 89 Logan Summit weather station reports 32 degrees, and 15 to 25 mph northwest wind overnight and continuing this morning.

recent activity

No avalanches were reported locally since the first week of February.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

The snow is stable and avalanches are unlikely. An inch or two of new snow isn't enough to cause an increase in danger, but shallow wind slabs will form fairly quickly at upper elevations, and more than expected accumulation could create heightened conditions in drifted terrain over the weekend. Other objective hazards to watch for in the mountains today include loss of control or slide-for-life potential in steep terrain on smooth and solidly refrozen snow, and hitting shallowly buried rocks or other hazards at mid and lower elevations. Minimize resource damage and avoid riding over sage and bare ground.


Some accumulating snow is possible in the mountains today, with snow showers likely, and it'll be mostly cloudy with sustained west-northwest wind and 8500' high temperatures around 31 degrees. Snow showers will continue tonight, temperatures will drop into the mid teens, and an inch or two of accumulation is possible. Keep your fingers crossed, it looks like snow showers will again be likely tomorrow and tomorrow night, with 2 to 4 additional inches possible, and even an inch or two will help matters significantly.
