Multiple tornadoes were reported in the watch area Sunday evening, said CNN meteorologist Michael Guy.
“Primary threats into the early morning hours include the potential for a few tornadoes, in which a couple could be intense. Scattered damaging winds are also likely with isolated significant gusts to 75 mph,” Guy said.
A spokesperson for the Arkansas Division of Emergency Management said there was tornado damage and multiple downed power lines near the Martin Township area, about 70 miles northwest of downtown Little Rock, with one injury reported.
A family was reported to be trapped in their storm shelter but were later able to be helped and are safe, according to the agency.
As residents brace for more potentially severe weather in Arkansas and Missouri, recovery efforts are ongoing in Iowa, where several tornadoes touched down near Des Moines Saturday. Seven people, including two children, died in the storms, officials said.
Six Madison County residents were killed, according to county Emergency Management Director Diogenes Ayala. The oldest victim was 72 years old and the youngest was aged 2, Ayala said at a news conference in Winterset Sunday afternoon. He had earlier said there were two victims under 5.
A person in a rural area near the Lucas County city of Chariton was also killed, an official said.
Six people in Madison County were being treated for injuries sustained in the tornado, according to officials. Ayala previously said one adult had life-threatening injuries and three others had been hospitalized in serious condition.
“This is, I think, the worst anyone has seen in quite a long time,” Ayala said Sunday.
At least 2 EF3 tornadoes hit Iowa, NWS says
After the severe weather passed through, many residents began the arduous process of recovering from the damage inflicted.
“You really realize who cares about you and just makes you feel special, you know you have all these people who are willing to help you,” she told KCCI.
An initial estimate of the Madison County tornado that impacted Winterset showed it was an EF3, the NWS said.
Iowa Gov. Kim Reynolds issued a disaster proclamation for Madison County, allowing state resources to be used for response and recovery efforts, according to a news release. Additional counties may be added to the proclamation.
The Chariton tornado is also estimated to have been an EF3 with winds of 138 mph and was on the ground for more than 16 miles, according to preliminary NWS surveys.
Other tornadoes that touched down include an EF2 with estimated winds of 122 mph near Leon, which was on the ground for 19 miles, the NWS said.
An EF1 tornado with 110 mph winds occurred in Vinton, an EF1 with 100 mph winds struck in West Lake Park and an EF-0 tornado also impacted West Lake Park with 65 mph winds, according to the NWS.
The agency said Sunday it is still conducting damage surveys across the state and is working to determine how many tornadoes occurred.
