Snow is falling in Big Cottonwood Canyon, and summer is officially over at Brighton Resort.

Remnants of Tropical Storm Rachel collided with cold air moving into Utah from the northwest on Monday, Oct. 12. The collision dropped the first measurable snowfall of the 2026-27 season on both Brighton and Solitude Mountain Resort.

The National Weather Service said the merging storm systems pushed the snow level below 9,000 feet Sunday night into Monday morning.

Brighton closed its mountain biking, disc golf and scenic lift operations Sunday, Oct. 11, due to the weather. The resort had planned Monday as the final day of its summer and fall season, ABC4 reported. Instead, snow shut things down a day early.

NWS forecasters projected 4 to 10 inches of snow for the Upper Cottonwoods through Wednesday, Oct. 14, with up to two feet possible in the western Uintas. Both Brighton and Solitude posted videos on social media showing snow accumulating around their lifts, according to KUTV.

The early snow arrives after what KUTV described as an exceptionally dry 2025-26 winter season.

Two dates matter for the coming ski season. Brighton is urging pass buyers to act by Monday, Nov. 2. Season pass prices increase after that date. The resort confirmed the deadline in a Facebook post but has not announced specific pricing. Brighton's opening day for the 2026-27 ski season has not been set.

Solitude Mountain Resort, owned by Alterra Mountain Co., is targeting Friday, Nov. 20, for its opening day. Brighton, operated by Boyne USA, lists its opening date as to be announced.

NWS forecasters said tropical moisture lingering across the region would bring widespread precipitation through Wednesday, meaning more snow could pile up in the canyon before the week is out.
