A wave of tornadoes and wild storms continued its angry march across the Midwest and South on Sunday, raising the death toll to at least 11 and leaving homes and neighborhoods in ruin.

A 2-year-old girl in Tennessee died after being struck by a metal soccer goal post that was blown over by high winds.

Melanie Espinoza Rodriguez was transported to Vanderbilt Children’s Hospital, where she was pronounced dead, the Metro Nashville Police Department posted on its Twitter page Sunday evening.

Middle Tennessee was hit by a strong line of storms that knocked down trees and power lines earlier Sunday.

In Arkansas, where two children were missing when their mother's car was caught in floodwaters, Cove Creek/Pearson Fire Chief Doug Decker died early Sunday after being struck by a vehicle while checking water levels around 4 a.m. CT, Arkansas State Trooper Liz Chapman said. It wasn't clear if Decker's death would be attributed to the storms.

Police say 65-year-old Julia Schwede was killed when a tree was blown into her home Saturday night.

At least four people were killed and 49 injured Saturday after multiple tornadoes and wild storms swept through Van Zandt County, Texas, about 50 miles east of Dallas, Canton Mayor Lou Ann Everett said Sunday. She said crews were still working to assess the situation and the death toll could rise.

The storms tore through an area 35 miles long and 15 miles wide, she said. Homes were destroyed, trees and power lines downed. Thousands were without power.

"The damage was extensive in affected areas," Everett said. "I have just driven through some of it, and it is heartbreaking."

Canton resident Ernestine Cook said she rushed to a storm shelter just in time.

"It hit so hard, so fast. It just kept moving," she said. "I've never seen anything like it after 22 years of living here."

In Arkansas, the state Emergency Management Department warned that numerous roads in the state were closed because of flooding.
