Points saillants

Human triggered avalanches are possible today as clear skies and warm temperatures create unstable wet surface snow.  Carefully asses terrain and route options before committing to a slope. Watch for signs of instability such as roller balls and avoid steep terrain that has saturated snow.

     Minimal overnight refreeze and warm daytime temperatures are working in conjunction to create wet and saturated surface snow. The warm spring day's effect on the snowpack and has created conditions  possible for human triggered avalanches.  Steep slopes around rocks can heat up quickly and should be noted as potential trigger points. There has been plenty of evidence from recent roller balls and pinwheels that point to surface instability. Limit your chances of triggering an avalanche today by being cognizant of changing conditions as the day heats up. Avoid  traveling  on steep slopes during the heat of the day and use test slopes and visual clues to create mindful travel plans.

    Roller balls or pinwheels and deep boot pen are clues to inform all backcountry users that wet, saturated snow is present and unstable. Test slopes  may provide some level of information on stability. If you find these clues in the snowpack, look for alternate slopes.

Avalanche Discussion

  • The Sonora Pass Snotel  (8,770 ft) has not dropped below freezing since the early morning hours of 3/21.
  • Yesterday's field time at Sonora Pass was hot, humid and wet. Much of the snowpack regardless of aspect was fully saturated and wet. Humid air effected the snowpack greatly.
  • Today, clouds will clear, temperatures will increase and winds will stall. This will create an even more inviting climate for wet avalanches to occur.
  • As always, please submit your observations. Forecasters can't be everywhere in one day, but providing observations helps us write a more accurate forecast for you!
