DES MOINES, Iowa -- Wind chills across the state are expected to drop dangerously low Tuesday morning.
Very cold air and strong winds produce low wind chills, resulting in frostbite and the possibility of hypothermia if precautions are not taken.
Temperatures will plunge Monday night into Tuesday morning, with wind chills between -20 and -30 in northern Iowa. In central Iowa, wind chills around -15 are expected as well as wind gusts between 30 and 40 mph.
In temperatures like this, the National Weather Service says frostbite can occur within 30 minutes to exposed skin. You can reduce your risk of frost bite by wearing layers of clothing in addition to a hat and gloves.
