Illinois and Indiana – Rising water concerns are building across the Ohio River Valley as multiple rounds of rain begin Monday and continue through March 11, setting the stage for widespread river rises and scattered flooding.
According to the National Weather Service Ohio River Forecast Center, 2 to 5 inches of rain are expected across much of Illinois and Indiana over the next seven days, with locally higher totals topping 7 inches. The heaviest rainfall axis stretches from southern Illinois through central and southern Indiana, where saturated ground will increase runoff into already elevated rivers.
In Illinois, communities along the Wabash and Ohio rivers, including areas near Mount Carmel and Shawneetown, could see rapid water level increases by midweek. Across Indiana, river points near Evansville, Vincennes and along the White River basin are projected to approach action stage, with some locations potentially reaching minor flood levels as early as Wednesday.
As the system progresses east, Kentucky, Ohio and western Pennsylvania face similar concerns. River rises are expected to begin Wednesday, with scattered minor flooding and isolated moderate flooding possible late this week into early next week. Urban areas could also see brief flash flooding during heavier downpours.
Drivers should avoid water-covered roads, secure outdoor items and monitor local emergency management updates. Additional flood advisories or warnings may be issued as confidence increases in rainfall placement and river responses through March 11.
