Cleanup efforts continued Friday morning after severe storms spawned tornadoes that left at least four dead, three in Texas and one in Florida, destroyed hundreds of homes, tossed vehicles into buildings and left hundreds of thousands without electricity.

In Perryton in the Texas Panhandle, Ochiltree County Sheriff Terry Bouchard said three people were killed when the tornado struck Thursday afternoon.

Another person died Thursday night in the Florida Panhandle when at least one confirmed tornado cut through Escambia County, toppling a tree onto a home, county spokesperson Andie Gibson told the Pensacola News Journal.

Of the homes searched so far in Perryton, all but one occupant had been accounted for, so the main priority was going back over the area and the debris field to find that person, Perryton Fire Chief Paul Dutcher said on NBC’s “Today” show.

Dutcher estimated that 150 to 200 homes in the community had been destroyed and said that in the downtown area, many storefronts were totally wiped off and buildings had collapsed or partially collapsed.

“You keep hearing people say, ‘We’ll rebuild’ and ‘We’ll be back,’” he said. “And we will. That’s the hope we have.”

But the biggest concern for now is trying to help the families of those who were killed carry on, Dutcher said.

“It is such a tragedy,” Dutcher said. “All the stuff behind me, it can all be rebuilt, but those lives that we’ve lost is really the tragedy of everything,” the fire chief said while standing in front of a collapsed building and a pile of bricks and other debris covered the ground, partially burying a truck.

Sheriff Bouchard urged residents to remain home if possible as cleanup efforts continued in the town of more than 8,000 about 115 miles (185 kilometers) northeast of Amarillo, just south of the Oklahoma line.

Bouchard said in a social media post that the Thursday tornado destroyed homes, mobile homes, businesses and damaged the local police station. Bouchard did not immediately return a phone call for comment Friday, but said much of the county is without power.

“We (the sheriff’s office) are probably one of the only places with power in the county, thanks to our generator,” Bouchard said.

The National Weather Service in Amarillo was sending a survey team Friday to assess damage and determine the tornado rating in the Perryton area, meteorologist Brett Muscha said.

More thunderstorms are possible in the far northern Texas Panhandle and the Oklahoma Panhandle Friday afternoon and night, Muscha said.

The greatest chance of strong and severe storms are on the Oklahoma side with golf ball-size hail and 60 mph (97 kph) wind gusts, Muscha said, although noting the environment is not as favorable for severe storms Friday.

Ochiltree General Hospital treated 115 patients due to Thursday’s tornado in Perryton, according to a Facebook post.

“We kind of expected to see more last night and we didn’t,” interim CEO Kelly Judice said. “We just want people in our community to know that we’re here. We’re open. We have clinics open. We’re ready for business to take care of the people that need to be treated.”

Patients had minor to major trauma, ranging from “head injuries to collapsed lungs, lacerations, broken bones,” Judice said, and people with routine medical checkups planned were asked to reschedule.

The hospital is operating on a generator and some patients were being treated in a bright conference room since exam rooms in one clinic don’t have windows, Judice said.

After hitting Perryton, the storm system moved into Oklahoma, spawning several more suspected twisters in addition to high winds and large hail.

Observations Program Leader Forrest Mitchell at the National Weather Service office in Norman, Oklahoma, said survey crews were expected to head out Friday to southwest and west central Oklahoma and western North Texas to investigate possible tornados.

“Today (Friday), it looks like we may have a bit of a breather, which is fortunate so we can go take care of our surveying needs, and then we have another system coming in (Saturday) that may give us opportunity for severe weather” Mitchell said.

Nearly 590,000 customers were without electricity in Texas, Louisiana, Mississippi and Oklahoma Friday morning, according to the poweroutage.us website.

Texas Gov. Greg Abbott said Thursday he had directed the state Division of Emergency Management to help with everything from traffic control to restoring water and other utilities, if needed.

Meanwhile, flash flooding was reported in Pensacola, Florida, where between 12 and 16 inches of rain has fallen since Thursday evening, said Caitlin Baldwin, a meteorologist with the National Weather Service’s Mobile in Pensacola. She said the weather service had received reports of evacuations and water rescues in Pensacola following the deluge, which was the heaviest amount of rainfall the city had received since 2014.

In West Pensacola, flash floodwaters surrounded an apartment complex, prompting officials to evacuate the building of all 146 residents, using boats to remove some, and take them to a local community center, said Davis Wood, public information officer for Escambia County Public Safety.

No injuries were reported in that evacuation.

The storms left about 160,000 in Mississippi without power, though no injuries were reported, according to Gov. Tate Reeves.

The storm system also brought hail and possible tornados to northwestern Ohio.

A barn was smashed and trees toppled in Sandusky County, Ohio, and power lines were downed in northern Toledo, leaving thousands without power.

It was the second day in a row that powerful storms struck the U.S. On Wednesday, strong winds brought down trees, damaged buildings and blew cars off a highway from the eastern part of Texas to Georgia.

Also in Texas and other Southern states including Louisiana, heat advisories were in effect Friday and were forecast into the Juneteenth holiday weekend with temperatures reaching toward 100 degrees Fahrenheit (38 degrees Celsius). It was expected to feel as hot as 110 degrees Fahrenheit (43 degrees Celsius).
