bottom line

Another day of sun for the panhandle! Today looks like a beautiful day to be in the mountains. Think about the effects of the sun, while your out today. South facing slopes are going to heat up the fastest. Signs of instability on solar effected slopes are pinwheels, roller balls and observed loose snow avalanches. It looks like a good chance for snow later this week...cross your fingers!

Avalanche Problem 1: Persistent Slab
  • Type ?
  • Aspect/Elevation ?

A weak buried surface hoar layer still lingers in some locations. Expect to find this layer in areas near treeline, in protected open poeckets of snow. 

Avalanche Problem 2: Loose Wet
  • Type ?
  • Aspect/Elevation ?
  • Likelihood ?
    Certain
    Very Likely
    Likely
    Possible
    Unlikely
  • Size ?
    Historic
    Very Large
    Large
    Small

Look for the possibility of loose snow avalanches on solar aspects today. The longer a slope sits in the snow the more the avalanche danger increases.

Avalanche Problem 3: Deep Slab
  • Type ?
  • Aspect/Elevation ?
  • Likelihood ?
    Certain

The snow pack in getting complex but we can't forget about the instabilities deep in the snow pack. Even though the deep instabilities aren't showing signs of waking up, we still need to be vigilant in assessing them.

Disclaimer

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.  For a recorded version of the Avalanche Advisory call (208)765-7323.
