(CNN) The flooding in Nebraska has gotten so bad it's breaking records across the state.

About 9 million people in 14 states along the Mississippi and Missouri rivers are under a flood warning, according to CNN meteorologist Karen Maginnis.

Some of the records go as far back as 1960 and some are as recent as 2011, according to a press release from the Nebraska Emergency Management Agency, or NEMA. The majority of the records NEMA listed involved the Missouri River, which crested between 30 and 47.5 feet in different areas throughout the state since Tuesday, breaking previous records by 1 to 4 feet.

The Platte River in Louisville is expected to crest Sunday at 14.3 feet, breaking its 1960 record by 1.9 feet, NEMA said. The Elkhorn River at Waterloo crested at 24.6 feet on Saturday, breaking its 1962 record by 5.5 feet.

Much of the major flooding is expected to continue through next weekend, NEMA said. The Elkhorn River is the only river whose major flooding was expected to decrease to moderate on Sunday.
