Bitterly cold weather is expected to linger in the KIOS listening area through Tuesday morning.
Wind chills dropped to 30 below zero or lower Monday morning. Douglas County Health Department Resource Director Phil Rooney says when wind chills reach that level, hypothermia and frostbite can set in quickly.
"You can suffer frostbite in 10 to 15 minutes, 30 minutes would definitely be pushing it if you have exposed skin when you’re outdoors, but it’s important to remember that everybody’s a little different, so it’s not like we can lock in on a certain particular time frame, but we know that 10 to 15 minutes can often do it."
Rooney says if you have to be outside, you should dress in layers, and wear a hat and gloves. He says you also should avoid using combustible fuels in your home for warmth.
