(Radio Iowa) – Forecasters say high temperatures today (Friday) and tomorrow won’t get out of the single digits, and wind chills may hit 30-below tonight, so frostbite is a serious risk as Iowans clear the latest snowfall from their driveways.

Jolyn Schneider, nurse manager of the University of Iowa Burn Treatment Center, says they’ve received dozens of calls about frostbite in recent days, and she says Iowans need to take precautions to keep their fingers and toes covered while outdoors.

Schneider says if you think you have frostbite, you should get medical care right away, as the longer you wait, the greater the risk of needing to have a finger or toe amputated.
