"The river is not safe," said Battalion Chief David Harwood of the McHenry Township Fire Protection District. "It's moving water. We've had some very sunny days. That ice thins out very quickly."

Meteorologist Mark Strehl said that the weather will keep getting warmer this week, which will make ice on Chicago area's rivers and lakes much more dangerous in the coming days.

In another incident, a snowmobile driver rolled their sled and was injured.
