City crews can't do much about the ice.
Chicago officials say it's the homeowner's responsibility to take care of slippery driveways and sidewalks.
Emergency rooms around the area are seeing a significant increase in serious injuries caused by falls on the ice.
"Today, no hypothermia, a little bit of frost bite and a lot of falls - rib fractures, wrist fractures, knee and ankle injuries and an occasional head bump," said Dr. Martin Lucenti, Northwestern Memorial Hospital.
Doctors warn that the elderly are especially vulnerable to serious injuries in this weather.
