Good morning. This is Doug Chabot with the Gallatin National Forest Avalanche Forecast on Thursday, February 2nd at 6:45 a.m. Today’s forecast is sponsored by the Avalanche Alliance and Cooke City Super 8/Bearclaw Bob’s. This forecast does not apply to operating ski areas.
In the last 24 hours most mountains received a trace to 1” of snow with 2” falling in Cooke City. Wind is westerly at 15 mph and gusting to 35 mph. Temperatures are in the teens in the northern mountains and single digits down south. Today will be sunny with temperatures reaching the high 20s F as high pressure builds. Westerly wind will increase later this afternoon and gust 40+ mph tonight under clear skies.
In the mountains of southwest Montana two competing forces are at play. On one hand, after getting a good wallop of snowfall Friday and Saturday, buried weak layers that did not avalanche will become less reactive. On the other hand, the wind continues to blow and load slopes at all elevations and aspects which hinder this process. Additionally, we are untrusting souls at the moment. Weak layers of buried facets continued to break in every snowpit Dave and his partner dug in Cooke City (avalanche details and videos), and on Tuesday I was able to trigger a small avalanche in Lionhead from 50 feet away, a crystal clear sign of dangerous conditions (video). Further evidence of our snowpack’s instability include Saddle Peak avalanching twice in a week and all the avalanche activity that blanketed our area as recently as Tuesday (avalanche and weather log).
Avalanche conditions remain dangerous today. Wind is blowing snow and loading slopes. Weak layers in the top 3 feet of the snowpack, as well as sugary, weak snow at the ground, are still adjusting to the weight of the weekend snow and recent wind-drifting. I recommend you do as Ian I did on Tuesday: we consciously avoided avalanche terrain and runout zones (slopes underneath). Be patient. Stability will improve and slopes will become relatively safer as high pressure settles over us, but we are not there yet. A wise avalanche professional wrote last night, “Decision-making is currently difficult. There are multiple hazards to consider, conditions are dynamic, and obvious.”
Watch our recent videos and read the observations page for detailed information about additional field locations. Browse the Avalanche Activity Log and note nearly thirty entries since January 25, many of which include multiple avalanches.
