CHICAGO — Flash-flood flashback?
Heavy flooding is possible in Chicago as "torrential rainfall" and thunderstorms slam the city overnight, according to the National Weather Service.
The service issued a flash flood watch Tuesday night that is in effect until 10 a.m. Wednesday.
Rainfall could reach rates of two inches per hour. People in flood-prone or low-lying areas should monitor weather reports, as flash flooding can be "a very dangerous situation," the service said.
Chicago experienced near-record levels of flooding in April.
