from the Gallatin National Forest Avalanche Center - March 14, 2013 - this report is by Mark Staples. This advisory Does Not Apply to operating ski areas.
Warm weather is the story today. Temperatures this morning were a few degrees either side of 32 degrees Fahrenheit and winds were blowing 10 to 20 mph from the West and Southwest. Skies today will have some clouds which hopefully will keep the sun at bay. Mountain temperatures will be in the 40s Fahrenheit with winds continuing at 10 to 20 mph. Tomorrow a small disturbance and slightly colder temperatures may produce a few snowflakes. A better chance for colder temperatures and snowfall will arrive on Sunday.
Snowpack and Avalanche Discussion:
Bridger, Gallatin, and Madison Ranges, Lionhead Area near West Yellowstone, and Cooke City:
A combination of warm temperatures and a lack of loading has created generally safe avalanche conditions. We have found many stable slopes recently in Beehive and Bear Basins, Hyalite Canyon, and Lionhead near West Yellowstone. Even wind slabs seem to be well bonded.
How to travel today? Approach every slope as though it has its own unique avalanche problem. On south facing slopes, watch out for point releases of wet snow today since overnight temperatures barely got below freezing. On north facing slopes where the snow remains dry, there are some faceted layers lurking. If riding in committing terrain where the consequences of an avalanche would be severe, dig at least one snowpit and conduct stability tests. On all slopes, watch for big cornices which may break as temperatures warm and snow begins creeping downhill.
Today the dry snow Avalanche Danger is LOW. The wet snow Avalanche Danger is MODERATE.
The next advisory tomorrow morning at 7:30 AM. If you have any snowpack or avalanche observations, drop us a line at firstname.lastname@example.org or call us at: 406-587-6984.
