(NEW YORK) — The South is bracing for a potentially major winter storm this weekend, impacting Texas, Oklahoma, Louisiana, Arkansas, Mississippi, Alabama and Tennessee.
The storm is still several days away, so exact timing and locations are not yet clear. But as of now, more than 30 million people are under a winter storm watch, from Dallas to Little Rock, Arkansas, to Huntsville, Alabama, to Nashville, Tennessee.
Snow is expected to develop over the Plains on Friday and a wintry mix of sleet and freezing rain is forecast to the south. The storm will become more widespread Saturday morning.
Texas Gov. Greg Abbott said on Tuesday he was activating state emergency response resources ahead of the storm, saying the freezing rain, sleet and snow “could create hazardous travel conditions into the weekend and cause impacts to infrastructure.”
The system will reach the East Coast by Sunday and impacts could linger there into Monday. But the specific timing and what to expect is still unclear.

(NEW YORK) — New details about how police caught up to Claudio Manuel Neves Valente, the 48-year-old former Brown graduate student who allegedly perpetrated a mass shooting at Brown University and killed an MIT professor, have emerged after a dayslong manhunt where he made a series of moves designed to evade authorities.
Providence Police Chief Oscar Perez said local police helped track down Valente, who was found dead in a New Hampshire storage unit, thanks, in part, to surveillance video and a detailed tip about a vehicle being driven by a person who noted odd behavior by the suspect.
“I’m being dead serious. Police need to look into a grey Nissan with Florida plates, possibly a rental,” the tipster told police, according to a complaint released by Rhode Island authorities. “That was the car he was driving.”
The tip and surveillance video, along with the use of license-plate reader technology led investigators to a car rental agency in Massachusetts.
There, police obtained a copy of the rental agreement with the suspect’s name, as well as video of the suspect that matched the videos of the person of interest seen on the Brown University campus on the day of the shooting, the complaint said.
That discovery ultimately led investigators to a storage facility in Salem, New Hampshire, where the suspect was found dead, officials said.
Financial records and video evidence confirmed that the storage unit belonged to the alleged suspect and that the rental vehicle was connected to both the Rhode Island and Massachusetts cases.
Authorities identified the suspect as Valente, a Portuguese national and former Brown University student whose last known address was in Miami, Florida. Officials said Valente died by suicide Thursday evening.
Officials confirmed that Valente was found with a satchel containing two firearms, and evidence recovered from the vehicle matched what was found at the Providence crime scene.
Federal authorities confirmed that shortly before 9 p.m. on Thursday, FBI SWAT teams executed court-authorized search warrants at a storage facility in Salem, which is where they found Valente’s body.
Portugal’s Instituto Superior Técnico (IST) confirmed to ABC News that Cláudio Manuel Neves Valente studied between 1995 and 2000 in the school’s physics engineering program, the same one attended at the time by slain MIT professor Nuno F.G. Loureiro.
A 1998 announcement in Portugal’s official Diario da República referred to Valente’s appointment as a teaching assistant at IST and a 2000 notice in the same publication mentions his termination from the role.
A spokesperson for IST declined to comment further on Valente’s history at the institution, due to the ongoing investigation and out of respect for the friends and family of Loureiro.
Brown officials confirmed that Valente was enrolled at the university from the fall of 2000 through the spring of 2001 as a graduate student in physics, entering Brown’s graduate program in September 2000 before taking a leave of absence in April 2001 and formally withdrawing in 2003.
“He was not a current student, was not an employee and did not receive a degree from the University, attending for only three semesters as a graduate student until taking a leave in 2001 and formally withdrawing effective July 31, 2003,” Brown University President Christina Paxson wrote in a letter to students and faculty Thursday.
During his time at Brown, he was enrolled only in physics courses, which were typically held in the Barus & Holley building. University records indicate he has had no active affiliation with Brown for more than two decades.
Police said the suspect acted alone and that there is no indication, at this time, of additional planned attacks. Investigators have not identified any writings, known criminal history or clear motive.
Officials said forensic teams are still processing evidence recovered in New Hampshire, including firearms, and will compare it with ballistic and DNA evidence from the Providence crime scene.
Paxson said the university is still reviewing how the suspect gained access to the building. She said the building was unlocked that day because exams were being held, and the university will examine security procedures moving forward.
Investigators said Valente obtained lawful permanency in April 2017 and was issued a green card.
Secretary of Homeland Security Kristi Noem said in an X post that Valente received his visa through the diversity visa lottery program, and announced that, at President Donald Trump’s direction, she was pausing the program.
Each year, the State Department awards up to 50,000 immigrant visas to “winners” of the diversity visa lottery. The program was created by Congress in 1990 to allow applicants from countries with low rates of immigration into the U.S. to come here.
The winners are selected at random, but they must still go through a lengthy application process, which includes submitting criminal records, being interviewed at an embassy or consulate, and meeting other requirements, such as having a High School Diploma or two years of work experience. Applicants are then allowed to apply for lawful permanent resident status.
Investigators said they identified Valente by name late Wednesday night and weighed whether releasing his identity could cause him to flee or take further action.
Officials said they believed he might return the rental car in Boston or attempt to leave the area, and they wanted the opportunity to arrest him without alerting him that police were closing in.
Officials said it remains unclear exactly when the suspect took his own life, but noted that he signed into the storage facility but was never seen leaving.
The site was secured by federal agents, and investigators said an autopsy will help determine the timing of his death.

(LOS ANGELES) — Heavy rain and dangerous flooding left one person dead in Redding, California, the mayor announced on Sunday.
It comes as flood watches are in effect for more than 30 million across California due to the threat of heavy rain and flash flooding in the coming days.
Redding Mayor Mike Littau said in a post on Facebook that local police and fire crews have been out doing water rescues while Public Works and Redding Electric Utility have been working to clear roads and restore power to customers.
Cities across Northern California on Sunday saw roadways inundated with flooding, leaving vehicles stranded.
The deadly flooding is due to repeat atmospheric rivers that continue to swamp the West Coast.
A Flood Watch was announced for much of Northern California, including Redding and Sacramento, on Saturday, with some areas expected to get 4 to 6+ inches.
On Christmas Eve Wednesday, another coastal storm will set its sights on the West Coast, but this time Southern California will bear the brunt.
There is growing concern for potentially significant flash flooding, mudslides and debris flows impacting portions of SoCal, as heavy rain sweeps across the region. The greatest concern will be across wildfire burn scars.

(BOSTON, Mass.) — It was Thursday morning when investigators definitively determined the same individual opened fire on a study group at Brown University and, two days later, murdered an MIT professor — raising fears among law enforcement officials that the killer may have had other intended targets, according to the top federal law enforcement official in Boston.
“We had no idea if he had a hit list and these were just the first two stops on his tour,” Leah Foley, the United States Attorney for the District of Massachusetts, told ABC News on Friday.
Foley said that the suspect, Claudio Manuel Neves Valente, was found dead in the New Hampshire storage unit with two 9mm Glock firearms equipped with green laser sights, five magazines with nearly 200 rounds of ammunition and nearly $900 in cash. In his car, investigators said they found more ammunition and body armor.
“This was highly premeditated and he was definitely equipped for the mission that he sought out to do,” Foley said.
Neves Valente, 48, died from a self-inflicted gunshot wound, police said.
On Friday, an autopsy was underway to determine how long the suspect had been dead by the time his body was found. Ballistics tests and DNA tests were underway.
Investigators were also searching through the contents of three USB thumb drives found in the suspect’s car to see if they contained clues about a motive. It is unclear at this time if the suspect had any other potential targets, according to people familiar with the investigation.
Foley said investigators believe Brown University and the MIT professor — Nuno F.G. Loureiro — were intentional targets, but they do not know why.
“I don’t know that even if he had explained why, that that would be an answer that is satisfactory to anyone,” Foley said. “He was evil.”
The possibility that the killer could have struck again infused the manhunt with new urgency. Federal agents fanned out across four New England states and posted up at airports in Boston and Hartford.
“We had no idea if he was going to act again in New England or try to leave New England,” Foley said.
Neves Valente had already switched license plates once, according to authorities. In the car, investigators said they found another expired plate.
The suspect was a former Brown graduate student who attended the school some 25 years ago, school officials said. He had enrolled as a Ph.D student in Brown’s physics program in 2000 and attended for less than a year, before going on a leave of absence and then withdrawing.
Neves Valente and Loureiro were both Portuguese nationals and had attended the same physics engineering program at Instituto Superior Técnico in Lisbon, the school confirmed to ABC News.
