18 people have died due to floods and storms in the South and Midwest of America.

According to the Associated Press (AP), the death toll from Saturday's storm and subsequent flooding due to continuous rain has risen to 18 as of Sunday local time.

Among the dead are 10 from the western part of Tennessee, 2 from Kentucky, 2 from Missouri, 1 from Indiana and 1 from Arkansas. The addresses of the other two have not been disclosed. 

Storms from Arkansas to Ohio and persistent heavy rains in Tennessee, Kentucky caused river flooding. Floods and storms caused the most damage in Tennessee, according to the National Weather Service . 

10 people died due to tornadoes in Tennessee . More than a thousand houses, commercial structures, roads, public places have been flooded. 

In Kentucky, a 9-year-old boy was swept away by floodwaters on his way to the school bus, and in Arkansas, a 5-year-old boy died after a tree fell on his house, police said. A 16-year-old volunteer died in an accident while rescuing people trapped in a storm in Missouri.

According to Leyne Wilkerson, mayor of Frankfort, Kentucky, the river reached 47 feet on Sunday and is expected to reach 49 feet by Monday morning.

Since the city's flood wall system can hold 51 feet of water, Mayor Wilkers said that less than 51 feet of water can be prevented from entering the city. Meteorologists are warning that floods may occur as torrential rains continue in some states. Parts of Alabama, Georgia and Florida will continue to experience storm surges throughout the day, the weather service said. 

Emergency officials in north-central Kentucky have ordered mandatory structure evacuations for Falmouth and Watler. Officials there ordered the evacuation of the structure to prevent a repeat of the river, which reached 50 feet (15 meters) 30 years ago, killing five people, according to AP. The National Weather Service has estimated that large floods may occur again in dozens of places in different states.
