Powerful storms that generated flooding and tornadoes across the south-central United States killed at least seven people at the weekend.
More flooding and tornadoes are possible as storms roll eastward in a band stretching from Alabama into the Ohio River valley. A flood warning was in effect for rivers in Arkansas, Mississippi and Louisiana.
Levees were straining to contain the floods in Missouri. Several rivers are still rising, including the Meramec near St. Louis, where hundreds of people are sandbagging to protect homes and businesses.
More severe weather was expected in the South.
The storm that tore through the central United States from Texas to IL could spawn damaging winds, hail and tornadoes as it heads into parts of the Middle Atlantic and Northeast, the National Weather Service said. Parts of the Florida Panhandle could be affected by severe thunderstorms or high winds and unsafe rip currents.
Earlier a Canton fire department captain said he believed five people had been killed.
Authorities are still notifying next of kin about the other two who were killed.
The weekend round of storms included high-intensity winds, hail and isolated tornadoes in East Texas, where four people died. According to CNN, one of those killed was a 72-year-old woman who was stranded in her auto as it was swept away by flood waters. The 72-year-old woman was a passenger in a vehicle that was swept of a highway in Christian County.
The Rankin County sheriff's office reported that a 7-year-old boy had unplugged an electric golf cart, dropped the cord in the floodwaters on the ground and was shocked.
Some 71,000 customers in the state were without power on Sunday morning, according to Entergy Arkansas, though service to all but 15,000 had been restored by Monday morning.
Crews in the state were still looking for an 18-month-old girl and 4-year-old boy after the pair were in a vehicle that went off a bridge in floodwaters as of Sunday night, April 30.
"It is heartbreaking and upsetting to say the least", Canton Mayor Lou Ann Everett told reporters at a news conference Sunday morning.
Rescue operations were hindered by the weather, Judge Don Kirkpatrick, the chief executive for Van Zandt County reportedly said. The National Weather Service confirms at least five tornadoes struck Eustace, Caney City and Canton in Northeast Texas.
Texas Gov. Greg Abbott has not declared a state of disaster in Van Zandt County, where four tornadoes touched down Saturday killing four and injuring scores of others, but he expects to make a decision soon.
Tornadoes tore roofs off homes, ripped trees out of the ground and tossed cars around "like toys", one witness said.
