Dozens of people are still missing in Tennessee after the second-deadliest tornado in state history ripped through Nashville and nearby areas, leveling buildings and killing at least 24 people.

In hard-hit Putnam County east of Nashville, where Monday night’s twister left at least 18 dead and dozens injured, 38 people remained missing Tuesday evening, officials said in a statement. Among the missing are many couples, and the county is asking for residents help.

Elsewhere, in the Nashville suburb of Mt. Juliet in Wilson County, police are searching for a 27-year-old man, Benjamin Fitch. He was reported to have been walking outside about an hour before the tornado hit, waiting for a ride back to his home state of North Carolina, authorities said.

“Benjamin’s ride arrived in Mt. Juliet to pick him up, but he was not located. He does not own a cell phone, and his family members are concerned about his well-being,” Mt. Juliet police said in a tweet.

It was unclear Wednesday morning if any people were missing in other areas hit by the tornado, including Davidson County.

Country music stars like Carrie Underwood, Kacey Musgraves and Faith Hill meanwhile shared their concerns and personal accounts of the disaster.

Underwood told “TODAY” that her husband was at their Nashville home with their two young children during the tornado and rushed to take shelter. “He said he had to go upstairs at like 2 a.m. and grab the boys and take them down to a little safe room in our house,” Underwood said.

The number of missing in Putnam County was originally 77, but was lowered as officials went door to door searching for residents, NBC Nashville affiliate WSMV reported.

At least 88 people in the county were treated at hospitals for their injuries, Putnam County Mayor Randy Porter said.

“The damage is dramatic to see,” Porter said after touring the county by helicopter.

Tuesday’s tornado was the second deadliest in Tennessee history, according to the National Oceanic and Atmospheric Administration’s Storm Prediction Center. The most fatal was on March 22, 1952, when twisters killed 38 people in the state. Another deadly tornado came on Feb. 5, 2008, when 22 died, according to federal authorities.

Country star Kacey Musgraves, tweeted Tuesday that, “Me and my fam are safe but many friends aren’t so lucky … I’m so nervous to find out who the fatalities are.”
