We might have quite a mess on our hands...a Winter Storm Warning (that's the big deal one), is in effect for Gallatin and Madison Counties until Noon on Tuesday. Several inches of snow is expected in the valleys with up to 18" of snow to accumulate in the mountains.
Quite frankly, I was happy to have a ski season AT ALL last year even though making reservations was a pain. Bridger Bowl and other ski areas that used a sign-up system to limit traffic, don't expect to be using that this 2021-2022 ski season.
All of these Montana closing dates are subject to change at each ski resort's discretion, depending on end of season snow conditions and other factors. Several Montana areas have flexibility in their closing dates.
