Frigid conditions pushed Blue Mountain Ski Resorts to an early close on Saturday, but despite the chill, people still packed the slopes.

Mountain host manager David Stianche said that the ski slopes were set to shut down by 4 p.m., as opposed to a normal closing at 10 p.m., due to the dangerously low temperatures and brutal winds.

“The National Weather Service has advised that frostbite can occur within 30 minutes of exposure to the cold temperatures and high winds,” he said. “Those conditions have been with us for the past few days, especially when the sun goes down. That can be a little bit of a danger to our guests.”

While the NWS and many other groups have advised everyone to limit their outdoor activities thanks to the wind chill warning that stretched throughout the weekend to Sunday morning, Stianche said that business went on as usual.

“Actually, it’s quite good,” he said on Saturday afternoon. “It’s been quite a busy a busy day, even with the cold weather.”

Other local resorts, including Big Boulder, resolved to stay open during regularly scheduled hours despite the chill, according to the business’s guest services.

Temperatures for Saturday hit lows around -4 degrees, with wind chill values as low as -16 degrees. Conditions are expected to improve slightly by Monday.

Blue Mountain’s slopes returned to normal hours on Sunday, and Stianche is confident that everyone should operate normally for the foreseeable future.

If you are planning to fit in some skiing or snowboarding during the cold snap, make sure to take some precautions.

“Layer up and cover all exposed skin,” Stianche said. “Take frequent breaks, too. Go out, hit a few runs, then go back inside the lodge and warm up.”
