The Ohio River crested earlier than expected on Monday afternoon, at 55.06 feet.
The National Weather Service had predicted the river to crest Tuesday morning at 56 feet, which is considered moderate flood stage.
Normal flood stage is 52 feet.
Rain that fell Monday morning pushed the rain total for April 2011 to 11.85 inches, which is now the third wettest month on record.
The record is 13.68 inches in January of 1937. Second is 12.18 inches in March of 1964.
Between now and Wednesday, the Tri-state could pick up another two to four inches of rain, and possibly more, which would break the record.
More rain is not good news for some areas of the Tri-State that are already dealing with high water and flooding.
Portions of Eastern Cincinnati are underwater due to the Ohio River overflowing its banks.
For David Powell, the river water threatens the house he and his family just moved into. He suddenly has a river for his front yard.
"I'm afraid the water is getting too high. But, I'm going to wait a little bit longer and if it gets much higher, I think we're gonna go," says Powell.
He told FOX19 he'll head for a hotel if he has to, and leave behind a neighborhood that Ohio River is slowly swallowing.
Meanwhile, pizza bar owner Mark Murray felt waterlogged and beaten down by Mother Nature.
"It's just distressing, it's distressing. You know. We've just, we have a lot of rain. Too much," said Murray.
