NEW WEATHER STATIONS IN THE PARK - NOVEMBER 2, 2018

Recent weather in the park is reminding us that winter is on the way.  The valley is primarily snow free, but a recent storm that has since melted away is beginning to build the winter snow pack up high.  We can say this with much higher confidence today thanks to our two brand new weather stations in the Surprise Lake area!  The Surprise Meadow station is indicating 14" of snow on the ground right now...The other station on Surprise Pinnacle is telling us that while raining in the valley, temperatures at 9,500' remain below freezing.  This information is part of an interagency effort to increase the data available to the Bridger-Teton Avalanche Center for daily forecasts.  The Lower Saddle weather station will also remain in service this winter as long as Mother Nature allows it!  Links to these stations are available on the Homepage and we encourage you to use them throughout the winter season.  

Installing the Surprise Pinnacle weather station - Sept. 2018      

CONDITIONS UPDATE- OCTOBER 6, 2018

Over the previous few days 6"-18" of snow have fallen on the Tetons above 9000 ft.  With the fresh coat of snow and cold temperatures, early winter conditions will remain for the forecast-able future and probably carry into the actual beginning of winter.  All alpine areas will have some snow, ice, and verglas.

FALL UPDATE - SEPTEMBER 21, 2018

Although conditions remain warm and dry, climbers and hikers should be prepared to deal with changing conditions, including:

  • Snow, ice and verglas in shaded areas, especially on north and west aspects above 11,000 feet
  • Freezing overnight temperatures. On average, temperatures drop 3 degrees for every 1,000 feet of elevation gain.
  • Shorter days- usable light until 7:30-8:00 pm.
  • Rescue operations can be limited by reduced staffing, severe weather and limited helicopter use. Consider your climbing objectives carefully and be prepared for self-rescue. 

Specific route condition updates will be limited as we transition to fall and staffing is reduced. This Homepage will continue to provide periodic updates on general Teton Range conditions.

CONDITIONS UPDATE - SEPTEMBER 10, 2018

Most of the snow and ice from the August 28th storm has melted from the upper elevations. Expect mostly dry conditions on southern aspects. Pockets of snow and ice can still be found on northern and western aspects above 12,000'. Climbing experience and familiarity with the Teton Range will determine the need for ice axe and crampons.
