Widespread rainfall of two-thirds of an inch to 1 1/3 inches on Friday in addition to melting snowfall resulted in significant runoff into area streams and rivers.
The Des Plaines River was measured at 6.4 feet as of 1:30 a.m. Saturday and is expected to rise more and could reach the flood stage of 7 feet. In addition, the east branch of the DuPage River in Bolingbrook was at 18 feet as of 2 a.m. and like to rise to over 19 feet this morning.
"Snow and ice is resulting in poor drainage and significant ponding of water in some low-lying areas," according to the National Weather Service.
Motorists are advised not to drive through areas where water covers the roadway.
In addition, the National Weather Service is reporting that there is an increased potential for ice-jam-related flooding, especially on Sunday when temperatures are expected to be in the 40s.
