Concern is rising that the first major storm outbreak on the verge of spring could strike the nation's heartland, putting millions of Americans from Texas to Iowa at risk of potentially strong tornadoes.
Some scattered severe thunderstorms were expected to begin late Thursday in the Texas Panhandle and across western Oklahoma and parts of Kansas, the National Weather Service said. Large hail, damaging winds and possibly a few tornadoes were also expected, according to the forecasters.
The strongest storms are forecast to develop Friday in a zone that includes much of Oklahoma, Kansas and Missouri and areas of some nearby states.
“This is probably our first real event this season where people are really starting to pay attention getting into the spring storm season,” said Melissa Mayes, deputy director of the Washington County Emergency Management Agency in Bartlesville, Oklahoma, north of Tulsa.
More than 6 million Americans are at the highest risk of severe weather Friday in an area that includes the metropolitan areas of Kansas City and Tulsa, Oklahoma, according to the national Storm Prediction Center. Another 22 million people are at a slightly lesser risk in a zone that includes Oklahoma City; St. Louis; Omaha, Nebraska; and Milwaukee, Wisconsin.
“We're right in the middle of it,” said John Stipetich, deputy emergency management director in Douglas County, Kansas, home to the University of Kansas.
Stipetich has been working this week with forecasters to glean details of what's expected and then turn that into a situation report he can share with schools, government agencies and others in the community.
The general setup for the strong storms is a clash between warm air streaming north from the Gulf Coast and cooler Canadian air behind cold fronts, according to meteorologists with the private forecasting service AccuWeather.
In parts of the eastern U.S., this weather pattern is also expected to usher in extremely warm temperatures for this time of year by the weekend.
“Temperatures will be 20-30 degrees above average, with 80s reaching as far north as parts of the Ohio Valley and Mid-Atlantic,” federal forecasters wrote in their long-range forecast discussion. “Daily records could become widespread.”
The high temperature in Louisville, Kentucky, for instance, is expected to reach 81 degrees (27.2 Celsius) by Friday, the weather service predicts. Atlanta's high temperature is expected to hit 82 degrees (27.8 Celsius) by Saturday. The forecast for Washington, D.C., calls for a high temperature of 74 degrees (23.3 Celsius) on Saturday.
The spring storms in the forecast come near the start of what many call tornado season, which generally begins at different times in different parts of the United States.
In what has historically been known as Tornado Alley — a designation that typically includes Kansas, Oklahoma and Texas — the peak of tornado season is May into early June. But the season starts earlier in what is often called Dixie Alley made up of southern states such as Arkansas, Louisiana, Mississippi, Alabama and Georgia.
Experts recommend a few simple safety steps to take before tornadoes hit.
For Mayes and other emergency managers at this time of year, social media is a key tool for raising awareness of the risks that storm season brings.
“We will probably start pushing out some safety tips this afternoon,” she said.
In Lawrence, Kansas, emergency managers must deliver information and warnings to a mix of university students, staff and visitors who might not be familiar with Kansas weather.
“Even people who have lived in Kansas their whole life sometimes get confused about what the siren means,” Stipetich said. “If you hear the siren, there’s a tornado coming and you need to take cover.”

NEW YORK (AP) — No quick dispatching of disease investigators. No televised news conference to inform the public. No timely health alerts to doctors.
In the midst of a hantavirus outbreak that involves Americans and is making headlines around the world, the U.S. government's top public health agency, the Centers for Disease Control and Prevention, has been uncharacteristically missing in action, according to a number of experts.
To President Donald Trump, "We seem to have things under very good control," as he told reporters Friday evening.
To experts, the situation aboard a cruise ship has not spiraled because, unlike COVID-19 or measles or the flu, hantavirus does not spread easily. It has been health experts in other countries, not the United States, who have been dealing primarily with the outbreak in the past week.
“The CDC is not even a player," said Lawrence Gostin, an international public health expert at Georgetown University. “I've never seen that before.”
Not until late Friday did CDC actions accelerate.
Health officials confirmed the deployment of a team to Spain's Canary Islands, where the ship was expected to arrive early Sunday local time, to meet the Americans onboard. They said a second team will go to Offutt Air Force Base in Nebraska as part of a plan to evacuate American passengers from the ship to a quarantine center. Also, the CDC issued its first health alert to U.S. doctors, advising them of the possibility of imported cases.
The CDC's diminished role in this outbreak is an indicator the agency is no longer the force in international health or the protector of domestic health that it once was, some experts said.
The hantavirus outbreak is “a sentinel event” that speaks to “how well the country is prepared for a disease threat. And right now, I’m very sorry to say that we are not prepared,” said Dr. Jeanne Marrazzo, chief executive officer of the Infectious Diseases Society of America.
Early last month, a 70-year-old Dutch man developed a feverish illness on a cruise ship traveling from Argentina to Antarctica and some islands in the South Atlantic. He died less than a week later. More people became sick, including the man's wife and a German woman, who both died.
Hantavirus was first identified as a cause of sickness of one of the cases on May 2. The World Health Organization swung into action and by Monday was calling it an outbreak. About two dozen Americans were on the ship, including about seven who disembarked last month and 17 who remained on board.
For decades, the CDC partnered with the WHO in such situations. The CDC acted as a mainstay of any international investigation, providing staff and expertise to help unravel any outbreak mystery, develop ways to control it and communicate to the public what they should know and how they should worry.
Such actions were a large reason why the CDC developed a reputation as the world's premier public health agency.
But this time, the WHO has been center stage. It made the risk assessment that has told people the outbreak is not a pandemic threat.
“I don’t think this is a giant threat to the United States,” said Jennifer Nuzzo, director of Brown University’s Pandemic Center. But how this situation has played out “just shows how empty and vapid the CDC is right now,” she said.
The current situation comes after 16 tumultuous months during which the Trump administration withdrew from the WHO, has restricted CDC scientists from talking to international counterparts at times and embarked on a plan to build its own international public health network through one-on-one agreements with individual countries.
The administration has laid off thousands of CDC scientists and public health professionals, including members of the agency's ship sanitation program.
As this was playing out, Trump's health secretary, Robert F. Kennedy Jr., said he was working to “restore the CDC’s focus on infectious disease, invest in innovation, and rebuild trust through integrity and transparency.”
The CDC has not been completely silent on hantavirus.
The agency on Wednesday issued a short statement that said the risk to the American public is “extremely low,” and described the U.S. government as “the world’s leader in global health security.”
Said Nuzzo: “Not only was that not helpful, it actually does damage because a core principle of public health communications is humility.”
The CDC's acting director, Dr. Jay Bhattacharya, posted a message on social media that the agency was lending its expertise in coordinating with other federal agencies and international authorities. Arizona officials this week said they learned from the CDC that one of the Americans who left the ship — a person with no symptoms and not considered contagious — had already returned to the state. WHO officials said the CDC has been sharing technical information.
The CDC also is “monitoring the health status and preparing medical support for all of the American passengers on the cruise,” Bhattacharya wrote.
But federal health officials have mostly been tight-lipped, declining interview requests.
In interviews this week, some experts made a comparison with a 2020 incident involving the Diamond Princess, a cruise ship docked in Japan that became the setting of one of the first large COVID-19 outbreaks outside of China.
The CDC sent personnel to the port, helped evacuate American passengers, ran quarantines, shared genetic data on the virus, coordinated with the WHO and Japan, held public briefings and rapidly published reports “that became the world’s reference data on cruise ship COVID transmission,” said Dr. Tom Frieden, a former CDC director.
Some aspects of the international response to the Diamond Princess were criticized, and it did not halt the outbreak or stop COVID-19’s spread across the world. But some experts say it was not for the CDC's lack of trying.
“The CDC was right on top of it, very visible, very active in trying to manage and contain it,” Gostin said, while the agency's work now is delayed and subdued.
Instead of working with nearly all of the world's nations through the WHO, the Trump administration has pursued bilateral health agreements with individual nations for information sharing, public health support, and what it describes as “the introduction of innovative American technologies.” Roughly 30 agreements are currently in place.
That's not sufficient, Gostin said. “You can't possibly cover a global health crisis by doing one-on-one deals with countries here and there,” he said.
