Excerpts from the ChicagoTribune.com:

At least 10 people were rescued from submerged vehicles Saturday in Lake Forest after heavy rain caused flooding. No one was reported injured, but flood conditions prompted rescues on Illinois Route 41 near Deerpath Road and on Washington Circle. Some of those rescued were brought to the fire station to dry off and warm up. A few homes in the area were also reported flooded.
