Other areas of flooding are also expected. Wheeling police have helped a few drivers who have become stranded in deep water.

Peak thunderstorm activity occurred in Arlington Heights at about 4:55 a.m. Severe lightning has accompanied heavy rain.

Flooded basements are being reported in the northwest suburbs and north suburbs.

Another large area of storms already developed are heading toward Rockford. The backfill could meet up with the second group of storms and bring continuous rain for the next couple of hours.
