The death toll in the Southeast climbed to 18 on Saturday after less than a week of tumultuous weather — unusual warmth, tornadoes and torrential downpours — sparked flooding and caused damage that wreaked havoc during the Christmas holiday.

Two deaths attributable to weather were reported Saturday in Mississippi: two people who have been missing since Wednesday, bringing that state’s death toll to 10. Late Saturday, one death was reported in Alabama.

In Texas, meanwhile, residents hunkered down for what the National Weather Service was calling a “historic blizzard.” Some parts of the state’s panhandle could see as many as 14 inches of snow, with sub-zero wind chills and accumulating ice. Residents in Lubbock and Amarillo prepared for a storm expected to begin Saturday night.

Jason Strunk, the football coach at Lubbock High School, said he was checking his home’s pipes and laying out cat litter for traction on his sidewalk and driveway, just as he learned growing up and living in colder climates farther north. Strunk’s major concern was unprepared drivers going out on wet, icy roads.

“When we get an inch or two, people panic,” he said. “They really don’t know how to drive in this kind of stuff.”

Mississippi Emergency Management Agency spokesman Greg Flynn said 56 injuries were reported. In a statement, Flynn said preliminary damage estimates show 241 homes were destroyed or severely damaged.

More than 400 homes were affected, he said. Severe storms are forecast for Sunday night through Monday as a strong cold front pushes through. Tornadoes are possible, and residents are asked to remain alert.

The flooding is the result of downpours that have thrashed the Southeast since Wednesday, bringing record rainfalls in some areas. Four inches of rain walloped Mobile, Ala., on Wednesday — smashing the previous record of 2.2 inches set in 1990.

Six people were killed in Tennessee, including three who were found in a car submerged in a creek, according to the Columbia Police Department. The Tennessee Emergency Management Agency said Saturday that authorities were monitoring areas for potential flooding.

One person died in Arkansas, and dozens of homes were damaged or destroyed.

In Alabama, Gov. Robert Bentley (R) on Saturday visited weather-damaged areas in Coffee County. A statement from the governor’s office said that about 190 roads across Alabama were closed because of flooding.

Authorities on Saturday recovered the body of a 5-year-old boy who drowned after the car he was riding in was submerged by floodwaters on Friday, said Coffee County Coroner Robert Preachers. The search is ongoing for a 22-year-old man who was also in the car.

A flood warning was in effect late Saturday afternoon for parts of northern Alabama.

A tornado touched down in Birmingham on Friday evening, but damage was limited.
