KALISPELL, Mont. -

Ski resorts are worried it's too cold for skiers. Managers are cautioning skiers to bundle up, and some decided the risks aren't worth it.

Ski resorts across the Flathead are planning ahead for the frigid weather expected this week. Blacktail Mountain in Lakeside isn't even going to open Wednesday and Thursday.

While Whitefish Mountain hasn't shut down, they did close chair one, which leads riders to the summit, where temperatures have been recorded close to -15 degrees.

"This is a day-to-day decision, and obviously we take a look at all the factors.  Again it's that 20-below factor that’s always in consideration, so if we were to have that at the mid-mountain or lower, certainly we would consider closing the mountain at that point," said Whitefish Mountain Spokesperson Riley Polumbus.

This isn't the first time Whitefish Mountain has had to close chairlifts down.

Opening day of this ski season saw just as freezing temperatures, causing a delayed opening for chair one.

By mid-morning, skiers at the mountain didn't seem to be deterred, but skier Andy Wang says he may think twice if the weather gets colder.

"I guess we'll have to play it by ear.  We weren't really too sure what we wanted to do today, but we just decided to come out and give it a try and so far it's not been too bad," said Wang.

As the temperatures aren't expected to let up over the next few days, there will be plenty of big decisions for the mountain, and the skiers.
