Update: Flood Warning Extended Until 4 A.M. Tuesday

ARLINGTON HEIGHTS, IL — The National Weather Service extended its flood advisory warning for Arlington Heights until 4 a.m. Tuesday. This follows Sunday night's warning at around 10 p.m. due to elevated water levels throughout the area due to heavy rainfall since Saturday.

Flooding, some still significant, continues across the warned area as a result of the very heavy rain from Saturday night and Sunday. This includes the entire Chicago metro, where several roads remain closed. In addition, water rescues were ongoing this morning across portions of Grundy County. Prepare for the possibility of encountering flooded or closed roads throughout this evening. Additionally, many area rivers, streams and creeks are still rising and will remain elevated as a result of additional runoff.

As flooding is more difficult to recognize during the night, numerous roads are closed throughout Chicagoland. The NWS is advising people to avoid travel tonight, if possible. Many area rivers, streams and creeks will continue to rise and remain elevated Monday as a result of additional runoff.

Other areas experiencing flooding include: Chicago, Aurora, Joliet, Naperville, Elgin, Waukegan, Cicero, Hammond, Gary, Evanston, Schaumburg, Boilingbrook, Palatine, Skokie, Des Plaines, Orland Park, Tinley Park, Oak Lawn and Berwyn.
