Saturday's avalanche advisory: High danger

Posted By on Sat, Mar 11, 2017 at 8:34 AM

From the West Central Montana Avalanche Center: The avalanche warning has expired this morning, and the current avalanche danger in the West Central Montana Backcountry is still HIGH on wind loaded terrain above 7,000 feet. The avalanche danger is CONSIDERABLE on all other terrain. Below 7,000 feet the avalanche danger is CONSIDERABLE but will move towards HIGH as the day warms up and the sun starts to affect the snow surface. Conditions are variable and careful evaluation is critical to recreate safely in the backcountry today.

Good morning, this is Logan King with the West Central Montana Avalanche Center’s avalanche advisory for March 11, 2017. This danger rating does not apply to operating ski areas, expires at midnight tonight and is the sole responsibility of the U.S. Forest Service.

For the full advisory, including photos and video, go to the West Central Montana Avalanche Center website.

Here's what the National Weather Service's backcountry forecast has to say about the rest of the weekend:

The large scale pattern over the Western US this weekend into next week is a ridge of high pressure. However, there will be weather systems moving through the pattern, keeping weather active and causing periods of widespread mountain precipitation every couple days. The first system moves through Saturday night into Sunday morning, with snow levels between 4000 to 5500 (rising as one moves south). Several inches of fairly dense snow is expected in the high terrain overnight, turning to more  isolated showers by Sunday afternoon. Relatively warm systems, similar in nature to Saturday night's system, look to move through Monday night, Wednesday night, and Friday night.
