US Avalanche Danger Scale
Not Current Advisory
Good Morning. This is Eric Knoff with the Gallatin National Forest Avalanche Advisory issued on Sunday, January 31, at 7:30 a.m. On Site Management, in cooperation with the Friends of the Avalanche Center, sponsor today's advisory. This advisory does not apply to operating ski areas.
A ridge of high pressure has dominated our weather pattern over the past 24 hours bringing us sunny skies and calm conditions. This ridge will break down today as a weak low pressure system pushes in from southern Idaho.
Winds are currently calm out of the W-SW at 5-15 mph, but will increase as the day progresses to 15-25 mph along the ridgetops. Temperatures will remain mild today with highs in the upper 20's to low 30's F, but will cool off this evening with lows in the teens. The impact of this system will be felt more in the southern mountains which could pick up 6-8 inches of snow by tomorrow morning with the northern ranges picking up less than half that amount.
The Madison Range, southern Gallatin Range and the Lionhead area near West Yellowstone:
No new snow has fallen over our forecast area for the past four days which has helped slow avalanche activity. It has been three days since the last report of a human

The Bridger and northern Gallatin Ranges, mountains around Cooke City and the Washburn Range:

8th ANNUAL KING AND QUEEN OF THE RIDGE
The 8th Annual King and Queen of the Ridge will be held at Bridger Bowl on Saturday, February 13th. ALL proceeds go to the Friends of the Avalanche Center who use the money to promote avalanche education in southwest Montana. Last winter we taught 62 classes reaching over 4,300 people. You can help raise money to continue this education in 2 ways:
1). Get pledges and hike the ridge. You don't have to do 20 laps - you can get flat pledges and hike just once! Or you can test your mettle and try and break John Yarington's record of 27 laps in 5 hours.
2). Sponsor someone. If you don't have someone to sponsor, consider sponsoring Mark, Eric or myself since we'll be hiking for dollars.
