Americans in the midwest braced for extreme weather on Memorial Day amid floods and storms across the centre of the US that have already left 12 people dead.

With regions of Nebraska, Indiana, Ohio and Illinois braced for potential tornados and extreme flooding, plans of barbecues and pool parties may be changing for evacuation.

Other parts of the nation are already undergoing severe weather, including floods that killed twelve in the Central US.

The Arkansas River is expected to see flooding four feet above the record, meaning “catastrophic flooding is possible in the towns of Van Buren and Fort Smith,” said CNN meteorologist Dave Hennen.

In Oklahoma, where six people were killed in severe weather last week, Governor Kevin Stitt warned the situation “still could get worse,”.

“We still have water still rising in the east,” said Mr Stitt. ”We are not out of the woods yet.”

A state of emergency remains in effect for all of Oklahoma on Monday.

Over 100 injuries have been reported at local hospitals, according to the state health department said.

Meanwhile, cities in South Carolina and Georgia are expected to hit over 100 degree fahrenheit, record-breaking temperatures on Memorial Day, and the Grand Canyon is expecting snow.
