(UNDATED) - Monday's torrential rains could produce flooding that extends into July.
The National Weather Service says the White River could crest in Indianapolis as early as Monday night.
Boone, Hamilton, Shelby and Tippecanoe counties could also see flooding.
As the water moves downstream, the floodwaters could affect Morgan and Bartholomew counties and the Covington area late this week, with low-lying areas in southwest Indiana to follow.
Hydrologist Al Shipe says northeast Indianapolis has been drenched with up to six inches of rain, still short of the 9-inch downpour in 2003.
But he says eastern and southern Marion County, and parts of Johnson and Shelby counties, are reporting their worst flooding in 30 or 40 years.
The National Weather Service has issued a flood warning until 3:00PM Tuesday for Marion, Hamilton, Johnson and Shelby counties, and parts of Boone, Hancock, Rush, Bartholomew and Decatur counties.
