Search and rescue teams in Alabama are using dogs and heat-detecting drones to search for victims of the deadly tornado that tore through the southeastern part of the state, as new drone video and photos show the scale of the devastation.

Lee County Sheriff Jay Jones said Monday at least 23 people were killed and 90 were injured when the giant EF4 twister with 170 mph winds hit the rural community of Beauregard, and dozens are still missing.

The tornado impacted what the sheriff described as a rural area that had a lot of mobile homes and manufactured-type housing. The twister created a debris field that spread over hundreds of yards, according to Jones, with some debris being thrown a half-mile away.

Authorities were expected to give an update on search and rescue efforts at 11 a.m. ET, but said earlier that crews were  “basically using everything we can get our hands on” to comb through what was left of homes.

Harris said all but six of the people killed in the storm have been identified, and his office soon will begin contacting families about funeral homes and arrangements. He also warned that the overall death toll could still increase as searches continue.

Chris Darden, meteorologist-in-charge at the NWS’ Birmingham office said at a news conference it was the deadliest tornado in the United States since the twister that hit Moore, Oklahoma in 2013. The storm had a track of at least 24 miles.

Alabama Gov. Kay Ivey said the tornado ravaged a “tight-knit” community of people.

“We lost children, mothers, fathers, neighbors, and friends,” she said.
