People in central Tennessee witnessed horrifying scenes of destruction and death when deadly tornadoes hit their communities this weekend. Six people were killed and dozens more were injured by the powerful storms that toppled a mobile home onto another, tore off roofs from houses and flattened a church.

On Sunday, emergency crews and residents worked to clear the damage caused by the weekend tornadoes and storms that also flipped over vehicles and cut off electricity to tens of thousands.

Marco Tulio Gabriel Pérez traveled from Atlanta to Nashville after learning that his sister and nephew, aged 2, died in the tornado. He said two other children in the family had minor injuries.

Pérez and his relatives sobbed as they searched through the debris of the trailers on Sunday morning.

“A tragedy occurred here, sadly. It was a tornado, as you can see here. She lived in this trailer. The other trailer fell on my sister who died. She was under it, the other trailer was on top,” Pérez said in Spanish to The Associated Press.

The Metropolitan Nashville Police Department named the victims who died north of downtown as Joseph Dalton, 37; Floridema Gabriel Pérez, 31; and her son, Anthony Elmer Mendez, 2. Dalton was in his mobile home when the storm threw it onto Pérez’s home. Two other children were taken to a hospital with non-life-threatening injuries, the department said in a statement.

Officials in other areas confirmed that three people, including a child, died after a tornado hit Montgomery County 50 miles (80 kilometers) northwest of Nashville near the Kentucky border on Saturday afternoon. They did not give names right away. About 60 people were treated for injuries at local medical facilities, including nine who were in critical condition and moved to a Nashville hospital, said Jimmie Edwards, Montgomery County’s director of emergency services.

City officials said 21 people were injured in Nashville, and 13 of them were hospitalized after a church north of downtown crumbled in the storm. Nashville emergency officials said in a news release that they were in stable condition later.

Donella Johnson, the pastor’s wife, said in a Facebook video that the sanctuary and activities building at Community Baptist Church in Nashville were completely destroyed. She said some members who were trapped by the debris had to undergo emergency surgeries for broken bones.

The church website had announced an appreciation banquet for the Johnsons for late Saturday afternoon.

“We have seen unimaginable devastation, but we did not lose any lives,” the Rev. Vincent Johnson said. “God took brick and wood and metal and twisted it in a tornado … yet God protected us.”

The National Weather Service said at least six tornado tracks were reported Saturday in central Tennessee. Cory Mueller, a meteorologist with the agency in Nashville, said they were sending out teams on Sunday to verify these possible tornadoes and assess their intensity.

Mueller said it was normal for tornadoes to occur during this season.

Joe Pitts, the mayor of Clarksville in Montgomery County, said it could take a few weeks before everyone had power back. He said residents of the city of about 166,000 helped each other clean up from the destructive storms on Sunday.

“We know we have people who are suffering from losing lives and property,” Pitts said. “One thing I love about this city is that when someone has a problem, we support that problem.”

At a press conference with Metropolitan Nashville leaders, Mayor Freddie O’Connell said that more than 20 structures had fallen there because of Saturday’s storm and that “many others had significant damage.”

Teresa Broyles-Aplin, an executive at Nashville Electric Service, said electric substations in north Nashville and in nearby Hendersonville had major damage and that some areas could be without power for days.

She said a video that showed a fireball in the sky on Saturday evening could have been caused by Nashville Electric equipment.

“That shows you how much damage we’re dealing with at some of these substations,” she said.

People in the region are used to severe weather in late autumn. Saturday’s storm happened almost two years to the day after the National Weather Service recorded 41 tornadoes in several states, including 16 in Tennessee and eight in Kentucky. A total of 81 people died in Kentucky alone.
