This is the scene of a tornado ripping through a residential area after touching down near Wynnewood, Oklahoma, in the United States on Monday.

Tornadoes caused by a strong series of storms hit the Great Plains. Vehicles were overturned and homes were damaged, reported Fox News.

According to American media, at least two people were killed, one of them a 76-year-old man.

Ms Jessica Randolph, a cashier at the Love's Travel Stop in Paul's Valley, Oklahoma, said the tornado came so close that managers ordered employees and customers to take shelter. Despite the danger, she said she was not frightened. "Not for me. I'm used to it."

This is the start of what is expected to be a period of unsettled weather in the United States' midsection. About 41 million people from Houston, Texas, to Sioux City, Iowa, were going to be affected by stormy weather, reported NBC News.

Another storm system may sweep across northern Texas to Missouri today.
