(CNN) — A heightened risk of severe weather is expected across a large swath of the southern United States on Saturday and Sunday – days after storms cut a deadly path across Texas, Florida and Mississippi.
The Storm Prediction Center said the enhanced risk is centered on Oklahoma, southern Kansas, and portions of the Texas Panhandle – including Perryton, which was hit by an EF-3 tornado on Thursday.
The threat includes “damaging hail as large as golf balls, severe to extremely severe gusts over 70 mph, and a few tornadoes from southeastern Colorado to northwestern Arkansas,” according to the SPC.
The majority of the storms are expected during the later afternoon and evening hours.
On Sunday, the highest risk level is centered across the lower Mississippi River Valley, including Arkansas, much of Mississippi, and northern Louisiana as the storms from the previous night move eastward during the early morning.
A new round of storms is likely to develop across this region and into the Florida Panhandle Sunday afternoon and evening, bringing damaging winds and large hail, along with a few isolated tornadoes.
Heavy rainfall could lead to isolated flash flooding in the deep South, especially portions of the Florida Panhandle and northern and central Florida.
Additionally, more than 40 million people – mainly in southern Louisiana, central and southern Texas and southern Florida – were under heat alerts Saturday, according to the National Weather Service.
A child and two other people killed in Texas
Three people, including a child, were killed in Perryton when a ruinous tornado slammed the town Thursday, the fire chief told CNN. The storm sent up to 100 people in the Panhandle town to the hospital with injuries ranging from head wounds to abrasions, the Ochiltree General Hospital interim CEO told CNN.
An 11-year-old boy, among the three killed by the tornado in Texas, was found dead in the neighborhood where he lived, Perryton Fire Chief Paul Dutcher told CNN.
One person died after severe weather swept through Mississippi overnight, the Mississippi Department of Emergency Management said in a release. Preliminary reports show that more than 70 homes have been damaged.
A person in Florida died after being trapped under a tree that fell on their home, Escambia County officials said.
The county, which includes Pensacola, was hit with flash flooding emergencies overnight, leading to high water rescues, the National Weather Service in Mobile, Alabama, reported early Friday, citing local rescuers.
“Widespread and significant” flash flooding was continuing in West Pensacola, Warrington and Gulf Breeze, Escambia County Emergency Management said. “Numerous roadways remain flooded with water entering several structures,” emergency officials said.
Nearly 150 residents of an apartment complex in Pensacola were moved amid the rising water Friday morning and taken to a community center for shelter, county officials said.
Warrington, just south of Pensacola, got nearly a foot of rain in just three hours. Radar estimates indicate as much as 16 inches of rain fell overnight, and more is expected Friday. A flash flood watch is in effect for the area until 7 p.m.
Many of the areas that saw severe conditions Thursday could see storms return as a level 2 of 5 slight risk of severe storms is in place for parts of the South, Mid-Atlantic and Southern Plains.
Large hail, damaging winds and tornadoes are possible in the slight risk areas, which include Montgomery and Mobile in Alabama, Little Rock, Arkansas; Jackson, Mississippi; and Tallahassee, Florida.
A marginal, level 1 of 5 risk is in place from South Dakota to Florida and for parts of the Mid-Atlantic. Cities in the marginal risk area, which could see large hail and damaging winds, include Philadelphia, Baltimore, Washington, DC, Denver and Jacksonville, Florida.
The destructive tornado that swept through Perryton was rated an EF3 that packed estimated peak winds of 140 mph, according to preliminary findings from the NWS. It touched down for about 11 minutes and traveled for a length of more than six miles.
The tornado damaged homes and businesses in the town of some 8,000 residents, including the local fire department and EMS, as well as multiple mobile homes, Dutcher said, noting many of the department’s trucks were damaged.
“A tornado formed, and it just dropped on us. It came out of nowhere. There were no sirens, no time to get to a shelter,” Perryton resident Jamie James said, telling CNN she had to ride out the storm in her truck.
“There was a time I thought I was going to die,” she said. “Everything went crazy. Dumpsters were flying, hailstones hitting the car.”
James’ home is still standing but the structure next to it is destroyed. She said the tornado is a devastating blow to the city she’s lived in for 15 years. “So many good people in this town. … We look out for one another.”
The city’s power facilities were shut off for safety purposes, according to Xcel Energy.
“Transmission lines supplying the city with electricity have sustained damage and many lower voltage distribution lines are down in the city,” said Wes Reeves, a spokesperson for Xcel Energy.
“Xcel Energy personnel are working to ensure the safety of Perryton residents and first responders. An estimated time of restoration is not yet available,” he added.
As of 7 p.m. CT Saturday, 125,000 homes and businesses across Texas were in the dark, according to the tracking website Poweroutage.us. In neighboring Louisiana, more than 139,000 were without power, and outages were also reported in Oklahoma, Virginia and Alabama.
And in Mississippi, more than 52,000 customers remained without power Saturday, according to Poweroutage.us.
Texas Gov. Greg Abbott issued a disaster declaration for communities impacted by the severe storms and tornadoes in Ochiltree and Cass counties, according to a news release from the governor’s office.
“The disaster declaration will further support Texas’ recovery efforts in response to extensive damage in those counties,” the news release read. “Additional counties may be added to the declaration as damage assessments are completed.”
The disaster declaration will help streamline the state’s ability to assist local officials recover and rebuild their communities, according to the governor.
Abbott also deployed state emergency resources to “meet urgent life-safety needs in Perryton, Texas,” according to a news release from his office.
“We remain ready to quickly provide any additional resources needed over the course of this severe weather event,” the governor noted in the statement.
Resources from surrounding areas have poured into the city to provide much-needed assistance.
Officials in Beaver County, Oklahoma, sent fire, law enforcement and EMS units to help, according to the county’s emergency manager Keith Shadden.
Neighboring city officials in Stinnett, Texas, also began sending officers and EMS crews. The sheriff’s office in Hutchinson County — which includes Stinnett — also sent rescue and emergency operations following the “devastating tornado,” according to a Facebook post from the office.
Medical help also came from staff at nearby hospitals who swiftly aided up to 100 people after the tornado struck, Ochiltree General Hospital Interim CEO Kelly Judice said.
“A few of them took patients to their hospitals, most of the staff just stayed here and worked,” she added.
On Thursday, there were two tornado reports in Texas, four in Oklahoma and one in Michigan, according to the National Weather Service, with the tornado in Perryton being the most significant.
‘People lost everything today’
The tornado, which was confirmed by the NWS, cut through some of Perryton’s main sections.
“It literally hit the residential, the downtown and then the industrial as well,” storm chaser Brian Emfinger told CNN.
The worst damages he saw were in the northwest part of town, where the tornado barreled toward a mobile home park directly in its path, Emfinger explained.
“The storm produced a wall cloud very quickly, and that wall cloud tightened up very rapidly, and then it just went to the ground very quickly,” Emfinger added.
Perryton’s fire department said via Facebook that one of their buildings was severely damaged.
“The Fire Department took a direct hit, (but) our trucks and ambulances are drivable!” the fire department said.
They also shared photos showing a fire station missing its roof and debris strewn throughout the building.
On the northeast side of town, about 300 people were sheltered inside Perryton High School after the area saw extensive damages, the school’s athletic director and football coach, Cole Underwood, told CNN.
“We have the gym space, and we have the capabilities to help the people that have lost everything and we’re more than willing to do that,” he said. “Sadly, there’s just not a list of things. … You think about what you need on hand, but people lost everything today.”
US Rep. Ronny Jackson, who represents Perryton, said the community needs help.
“If you are in the area, I ask that you do whatever you can to help your neighbors. Food, fuel, water, generators – anything you can.”
