Authorities say at least seven people have died as severe storms sweep across parts of the U.S. South, bringing high winds and unrelenting rain.

The National Weather Service in Birmingham, Alabama, said Saturday via Twitter that three people have been confirmed killed near Carrollton in Pickens County. The Alabama Emergency Management Agency said that an “embedded tornado within a long line of intense thunderstorms” caused the deaths.

Earlier Saturday, firefighters found the bodies of an elderly couple Saturday near their demolished trailer, the Bossier Parish Sheriff’s Office said via Facebook. The winds were so strong that the home was moved 200 feet from its foundation.

The deaths of the victims, who were the in-laws of a parish deputy, brings the storm-related toll in the state to three after a 75-year-old man was killed in Oil City, according to the Caddo Parish Coroner’s Office. Raymond Holden was in bed when the tree fell on his home, crushing him.

Bossier Parish Sheriff Julian Whittington told The Associated Press that a truck driver and a Benton police officer had a close call after being shocked by a downed power line.

“A power line was hanging across the road and a eighteen wheeler truck ran into it and got hung up in it and the Benton officer got there to help him,” Whittington said. Both were expected to survive.

The National Weather Service in Shreveport estimated that a tornado, with about around 135 mph (217 kph) winds, touched down in Bossier Parish.

Arkansas, Oklahoma and Texas on Saturday morning were clear of the severe thunderstorms that had passed through the night before. One person died Friday night in Texas when a car flipped into a creek in Dallas. Additionally, lightning from Friday’s stormy weather is suspected of causing two house fires in the North Texas cities of Burleson and Mansfield. Officials said no one was injured.

Homes were damaged or destroyed in Missouri, Oklahoma and Arkansas on Friday, but no injuries were reported. Downed trees and power lines were widespread.

More than 85,000 people without power in Alabama, according to Alabama Power. According to PowerOutage.us, Mississippi had more than 61,0000 power outages midday Saturday. About 35,000 customers were without power in Louisiana. Outages were reported from Texas to Michigan.

In Tennessee, Memphis Light, Gas and Water said about 23,000 customers were without power Saturday morning. Damage was widespread throughout Shelby County, Tennessee’s most populous county that includes Memphis, including downed trees and power poles, some of which will need to be replaced, according to the utility.

Entergy Arkansas reported nearly 42,000 power outages Saturday morning, mostly in the southeastern part of the state. Southwestern Electric Power Co. reported nearly 5,000 customers in East Texas were without power Saturday morning.

The Oklahoma Department of Transportation reported Saturday morning that portions of several highways in the southeastern part of the state were closed due to flooding. The Arkansas Department of Transportation reported that portions of several state highways across the state, particularly in the southeastern portion of Arkansas were closed due to downed trees and power lines and to flooding.

On Alabama’s Gulf Coast, Baldwin County canceled school activities including sporting events for Saturday. The National Weather Service warned of high winds and flooding and the potential for 10-foot-high (3-meter-high) waves on beaches, where northern visitors escaping the cold are a common sight during the winter.

Many streams already are at or near flood levels because of earlier storms, and heavy rains could lead to flash flooding across the region, forecasters said. Parts of Arkansas, Tennessee, Mississippi, Missouri, Illinois and Indiana were under flash flood warnings or watches on Saturday.

The storm, bringing the threat of ice and snow to the Chicago area, prompted the cancellation of about 1,000 flights Saturday at Chicago’s two main airports.

The Chicago Department of Aviation’s online flight-tracking website showed that as of 10:30 a.m. Saturday about 950 flight cancellations were reported at Chicago’s O’Hare International Airport and more than 50 flights had been canceled at Midway International Airport.

Delays at O’Hare and Midway were averaging around 15 minutes, the department said.

The weather service issued a winter weather advisory, flood watch and lakeshore flood warning for the Chicago metropolitan area for Saturday and a winter storm warning for adjacent areas of northwestern Illinois.

The weather service said rain, possibly mixed with snow, freezing rain and sleet was expected through Saturday afternoon in the Chicago area before changing by evening over to snow and sleet, possibly mixed with freezing rain.

Breezy conditions were forecast with gusts as high as 45 mph (72 kph).
