Rescue workers fanned out again Wednesday through some shattered middle Tennessee communities after tornadoes ripped through the region, killing at least 24, some of whom have been identified.

At a news conference Wednesday morning, Putnam County Mayor Randy Porter said the death toll remained at 18 in the county east of Nashville, where a tornado damaged more than 100 structures. In the 2-mile path of destruction, some homes were ripped from their foundations and the wreckage was flung far away.

"We ask that you please keep those families in your prayers," Porter told reporters. "We have lots of folks, citizens, and families of Putnam County who are suffering this morning due to the loss of these loved ones."

Porter said the number of unaccounted for had "decreased dramatically" to 22 as of Wednesday morning after initially 78 missing people were reported.

"We're hoping to decrease it down to zero," he told reporters. Officials plan to search a 20- to 25-acre marshy field filled with debris before weather impacts efforts on Thursday.

All but one of the victims have been identified, according to Porter. Authorities still need to identify a 30- to 35-year-old white female with dark curly hair who is about 5-feet 8-inches tall and was found in the Echo Valley Apartment area.

Three members of a family in Cookeville, Tenn., were identified by family and friends as among those killed in the Putnam County twister. A post on Facebook from Lauren Pitts says that Josh, Erin and their 2-year-old son Sawyer Kimberlin are "all in heaven together."

"We’re devastated with this news," Pitts, a family friend, wrote. "They were a beautiful family."

"Erin was the best of our cousins. Josh was one of the best men I had the pleasure of knowing," Jesse Pitts wrote. "Sawyer was a beautiful, amazing little guy with so much life ahead."

Erin was identified as the " kindest most attentive teacher" by the parent of one of her students, Melodee Bartlett-Maples.

"She would often tell me the boys in this class were her favorites... I’m sure she has whispered this to all class moms," she wrote.

Gov. Bill Lee declared an emergency and sent the National Guard to help with search-and-rescue efforts. Police kept parts of Putnam County cordoned off, and imposed an 8 p.m.-8 a.m. curfew as the grim search continued into Wednesday.

"It is tragic and heartbreaking," Lee told "America's Newsroom" on Wednesday, saying a "large swath of the state" was impacted by the severe weather.

More than 140 buildings were shredded across Tennessee early Tuesday as the storms moved through, burying people in piles of rubble and wrecked basements.

The National Weather Service survey teams indicated that the damage in Nashville and Wilson County to the east was inflicted by a tornado of at least EF-3 intensity, with wind speeds up to 165 mph. One twister wrecked homes and businesses across a 10-mile stretch of Nashville that included parts of downtown and an abandoned prison.
