VALLEY VIEW, Texas (AP) — Powerful storms killed at least 18 people, injured hundreds and left a wide trail of destruction across Texas, Oklahoma and Arkansas after obliterating homes and destroying a truck stop where dozens sought shelter in a restroom during the latest deadly weather to strike the central U.S.

The storms inflicted their worst damage in a region spanning from north of Dallas to the northwest corner of Arkansas, and the system threatened to bring more violent weather to other parts of the Midwest. By Monday, forecasters said, the greatest risk would shift to the east, covering a broad swath of the country from Alabama to near New York City.

Seven deaths were reported in Cooke County, Texas, near the Oklahoma border, where a tornado Saturday night plowed through a rural area near a mobile home park, Texas Gov. Greg Abbott said at a news conference Sunday. The dead included two children, ages 2 and 5. Three family members were found dead in one home, according to the county sheriff.

Storms also killed two people and destroyed houses in Oklahoma, where the injured included guests at an outdoor wedding, eight people in Arkansas and one person in Kentucky. Tens of thousands of residents were without power across the region.

In Texas, about 100 people were injured and more than 200 homes and structures destroyed, Abbott said, sitting in front of a ravaged truck stop near the small agricultural community of Valley View. The area was among the hardest-hit, with winds reaching an estimated 135 mph (217 kph), officials said.

“The hopes and dreams of Texas families and small businesses have literally been crushed by storm after storm,” said Abbott, whose state has seen successive bouts of severe weather, including storms that killed eight people in Houston.

Hugo Parra, who lives in Farmers Branch, north of Dallas, said he rode out the storm with 40 to 50 people in the bathroom of the truck stop. The storm sheared the roof and walls off the building, mangling metal beams and leaving battered cars in the parking lot.

“A firefighter came to check on us and he said, ‘You’re very lucky,’” Parra said. “The best way to describe this is the wind tried to rip us out of the bathrooms.”

Multiple people were transported to hospitals by ambulance and helicopter in Denton County, also north of Dallas.

No more deaths are expected and nobody was reported missing in Texas, said Abbott, though responders were doing one more round of searches just in case.

Eight people died statewide in Arkansas, Gov. Sarah Huckabee Sanders confirmed in a news conference Sunday evening. An emergency official said two of the deaths were attributed to the circumstances of the storm but not directly caused by weather, including a person who suffered a heart attack and another who was deprived of oxygen due to a loss of electricity.

The deaths included a 26-year-old woman who was found dead outside a destroyed home in Olvey, a small community in Boone County, according to Daniel Bolen of the county’s emergency management office. One person died in Benton County, and two more bodies were found in Marion County, officials said.

In Oklahoma, two people died in Mayes County, east of Tulsa, officials said.

In Kentucky, a man was killed Sunday in Louisville when a tree fell on him, police said. Louisville Mayor Craig Greenburg confirmed it was a storm-related death on social media.

A DEADLY SERIES OF STORMS

The destruction continued a grim month of deadly severe weather in the nation’s midsection.

Tornadoes in Iowa last week left at least five people dead and dozens injured. The deadly twisters have spawned during a historically bad season for tornadoes, at a time when climate change contributes to the severity of storms around the world. April had the second-highest number of tornadoes on record in the country.

Meteorologists and authorities issued urgent warnings to seek cover as the storms marched across the region late Saturday and into Sunday. “If you are in the path of this storm take cover now!” the National Weather Service office in Norman, Oklahoma, posted on X.

Harold Brooks, a senior scientist at the National Severe Storms Laboratory in Norman, said a persistent pattern of warm, moist air is to blame for the string of tornadoes over the past two months.

HOMES DESTROYED, ROADS BLOCKED

Residents awoke Sunday to overturned cars and collapsed garages. Some residents could be seen pacing and assessing the damage. Nearby, neighbors sat on the foundation of a wrecked home.

In Valley View, near the truck stop, the storms ripped the roofs off homes and blew out windows. Clothing, insulation, bits of plastic and other pieces of debris were wrapped around miles of barbed wire fence line surrounding grazing land in the rural area.

Kevin Dorantes, 20, was in nearby Carrollton when he learned the tornado was bearing down on the Valley View neighborhood where he lived with his father and brother. He called the two of them and told them to take cover in the windowless bathroom, where they rode out the storm and survived unharmed.

As Dorantes wandered through the neighborhood of downed power lines and devastated houses, he came upon a family whose home was reduced to a pile of splintered rubble. A father and son were trapped under debris and friends and neighbors raced to get them out, Dorantes said.

“They were conscious but severely injured,” Dorantes said.

WIDESPREAD POWER OUTAGES

The severe weather knocked out power for tens of thousands of homes and businesses in the path of the storms.

By late Sunday, more than 80,000 customers in Arkansas were without power. In neighboring Missouri, more than 90,000 were also without power. Texas reported 27,000 outages while 3,000 were reported in Oklahoma, according to the tracking website poweroutage.us.

Inaccessible roads and downed power lines in Oklahoma also led officials in the town of Claremore, near Tulsa, to announce on social media that the city was “shut down” due to the damage.

MORE SEVERE WEATHER IN FORECAST

The system causing the latest severe weather was expected to move east over the rest of the holiday weekend.

The Indianapolis 500 started four hours late after a strong storm pushed into the area, forcing Indianapolis Motor Speedway officials to evacuate about 125,000 race fans.

More severe storms were predicted in Illinois, Missouri, Kentucky and Tennessee.

The risk of severe weather moves into North Carolina and Virginia on Monday, forecasters said.
