Severe storms and isolated flash flooding are expected across the country over the next three days, beginning in the Southeast.
The multi-day event, which could bring strong winds, floods and tornadoes, comes as parts of the country are trying to recover from recent tornadoes that killed six people in Michigan and Oklahoma. The tornado risk continues this week for the Midwest and Southwest.
Five million people were at risk Monday for severe storms across the Southeast, stretching from central Arkansas to central Alabama. Threats include strong wind gusts, large hail, and a potential tornado.
The Midwest and southwest Texas will be on high alert Tuesday thanks to two clusters of storms that could bring 60 mph winds and flash flooding.
Straight-line winds from central Pennsylvania to central Louisiana will rush in as the middle of the week approaches, putting 27 million people at risk.
Deadly storms
Oklahoma is bracing for more severe weather, days after devastating tornadoes killed a mother and daughter in Fairview.
Jodie, 47, and Lexi Owens, 13, were found dead in a vehicle just west of Fairview about 10 p.m. Thursday. The pair were driving home after Jodie picked up Lexi from a friend's house, Jodie's brother Justin Zonts said.
Zonts said that the mother and daughter were racing home after receiving a tornado warning and had called and warned family at home to take shelter.
"She's telling them how they need to take cover. They've got a storm shelter put in their home. They just, they always try to be prepared," Zonts said. "But, unfortunately, she was on the phone with her daughter just as the storm hit."
"A tornado at night is sometimes essentially invisible, and she had, I'm sure, no idea that was right in front of her or coming right at her from the side," Zonts said.
He said his sister and niece were "constantly together" and joked they were attached at the hip.
Jodie and her husband, David, who have eight children, moved to Oklahoma in recent years, her brother said.
Last week's deadly tornado outbreak also struck Michigan, killing three people in the Union City area, as well as 12-year-old Silas Anderson in Cass County, Michigan.
