Flash Flood Threat, Too

While swaths of the Plains and Midwest are currently indrought, these repeated rounds of thunderstorms could also trigger areas of flash flooding, particularly in areas that have been soaked repeatedly this month.

That includes parts of the Great Lakes, Ohio Valley and Plains.

Be Prepared

There are steps you can take to stay safe in severe weather:

1. Know where to seek safe shelter when severe weather strikesbeforethe storm. If you live in a manufactured home, the safest place is probably either a designated community shelter or the closest building such as a church, industrial building or any building with reinforced concrete.

2. Have multiple ways of receiving official National Weather Service watches and warnings, including from yourphoneandNOAA weather radio. Make sure your devices are full charged in case you lose power and alerts are turned on to wake you up at night.

3. Seek safe shelterimmediatelywhen you receive a severe thunderstorm or tornado warning for your area.

4.Never drive into flood waters. You could be carried away and the road underneath could have been washed away.

Storm Fatigue

It has been yet another active March for severe weather in the U.S., including parts of the Midwest.

On March 6, four tornadoes struck southern Michigan, including an EF3 in Branch County killing three, an EF2 in Three Rivers and an EF1 tornado that claimed a life in Cass County.

Four days later, a lone supercell spawned 12 tornadoes across northeast Illinois into northwest Indiana, including the EF3 Kankakee, Illinois, tornado, which killed three.

Then on March 15, another 17 tornadoes were confirmed across central and southern Illinois.

NOAA's Storm Prediction Center has received 196 reports of and confirmed tornadoes in March, almost double the 20-year average of March twisters (104).

Chinese chipmakers claim nearly half of of local market as Nvidia's lead shrinks, IDC says

By Che Pan and Laurie Chen

BEIJING, April 1 (Rtrs) - Chinese GPU and AI chip makers captured nearly 41% of China's AI accelerator server ‌market last year, erodingNvidia's once-dominant position in one of its ‌most important overseas markets, according to data from an IDC report reviewed by Reuters.

The gains ​come as Beijing grows increasingly cautious about dependence on foreign chips, pushing government agencies and companies to adopt domestic alternatives after successive waves of U.S. export controls cut China off from Nvidia's most advanced products.

Total shipments of AI accelerator cards ‌by Nvidia, AMD, and ⁠Chinese chipmakers reached approximately 4 million units in China in 2025, the data showed.

Nvidia remained the market leader, shipping around ⁠2.2 million cards and holding a 55% share. But that figure marks a significant retreat for the U.S. chipmaker, which held a dominant market share in China's ​AI chip ​market. AMD carved out a modest ​presence, shipping roughly 160,000 cards for ‌a 4% share, the IDC data showed.

Chinese vendors collectively shipped 1.65 million cards, accounting for 41% of the total market — a milestone that underscores how aggressively domestic players have moved to fill the void left by tightening U.S. export controls.

Huawei Technologies emerged as the runaway leader among Chinese vendors, shipping ‌around 812,000 AI chips, roughly half of all ​domestically branded shipments. Alibaba's chip design unit ​T-Head claimed second place, shipping ​approximately 265,000 cards.

Baidu's Kunlunxin and Cambricon each shipped around 116,000 ‌cards, ranking them jointly third among ​Chinese vendors.

Hygon, GPU startups ​MetaX and Iluvatar CoreX accounted for 5%, 4% and 3% of total Chinese vendor shipments, respectively.

In 2025, the central government launched a new ​wave of AI infrastructure ‌spending, with local governments accelerating intelligent computing centers across provinces, many ​of which carried implicit directives to "buy Chinese."

South Korea and Indonesia expand cooperation on defense and energy as Mideast war disrupts markets

SEOUL, South Korea (AP) — South Korea and Indonesia agreed Wednesday to expand cooperation in defense industries, technology and supply chains as their leaders pledged to upgrade their strategic partnership in face of uncertainties stemming from the war in the Middle East, Seoul's presidential office said.

South Korea Indonesia

After a summit in Seoul between PresidentLee Jae Myungand Indonesian PresidentPrabowo Subianto,the two governments issued a joint statement pledging deeper economic ties and continued cooperation on joint defense projects, including fighter jets, trainer aircraft and anti-tank missile systems.

The two countries agreed to deepen cooperation on supply chains for energy, critical minerals and other resources. Lee described Indonesia as a vital source of natural gas and coal amid global energy disruptions caused by the war in the Middle East.

According to Lee's government, South Korean companies will receive about 820,000 tons of liquefied natural gas from Indonesia this year, enough to power all of the country's gas-fired plants for about 12 days.

The leaders expressed satisfaction with the two countries' cooperation in developing South Korea's homegrown KF-21 supersonic fighter, a program launched in 2015 with Indonesia as a partner. The first of these planes were rolled out last week and South Korea reportedly plans to export 16 of them to Indonesia.

Supreme Court weighs Trump's contentious attempt to limit birthright citizenship

WASHINGTON — Tackling one of President Donald Trump's most provocative policies, the Supreme Court on Wednesday considers the lawfulness of his proposal to limit the constitutional guarantee of birthright citizenship for people born on U.S. soil.

Announced on the first day of Trump's second term in office as part of his hard-line immigration policy, theexecutive orderat issue would limit birthright citizenship to people who have at least one parent who is a U.S. citizen or a permanent resident.

As a result, babies born to temporary visitors who entered the country legally or to people who entered illegally would not be citizens at birth.

Trump said Tuesday heplans to attend the oral argumentin person, which would be a first for a sitting president.

His executive order upends the traditional understanding of a provision of the Constitution's 14th Amendment known as the citizenship clause.

"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States," the clause states.

The clause, ratified with the amendment after the Civil War to provide equal rights to formerly enslaved Black people, has long been assumed by officials at all levels of the government to apply to almost anyone born in the United States, regardless of the legal status of their parents.

The few exceptions understood at the time included children born to diplomats and foreign invaders.

Trump's executive order was immediately blocked by courts around the country and has never been in effect. Most legal experts predict he faces an uphill battle to win the case.

The plan, if it were implemented, would affect thousands of babies born every year across the U.S.

One woman, who asked not to be identified to protect her family, was heavily pregnant last year when she heard about the executive order. Originally from Argentina, she now lives in Florida on a student visa and was immediately alarmed about what legal status her child would have.

"My baby was actually going to be one of the first ones impacted. I immediately went into panic mode," she said in an interview.

Determined to make sure her now-8-month-old son's citizenship was secured, she started making arrangements to apply for a passport for him before he was even born.

Although her son now has his passport, she said she is deeply sympathetic to other families expecting babies who remain unsure what will happen.

"I know there's probably a lot of different families and moms, pregnant moms, in my situation that are probably stressed," she said.

The administration's legal argument focuses on the "subject to the jurisdiction thereof" language in the citizenship clause, saying it has a much broader meaning than hitherto believed.

Solicitor General D. John Sauer argued in court papers that the citizenship clause was intended to apply primarily to the children of free slaves. People must be under the direct "political jurisdiction" of the U.S. and not have any allegiance to another country, he wrote.

He cited, among other things, the 1884 Supreme Court ruling in a case called Elk v. Wilkins that spelled out why Native Americans did not, at the time, have birthright citizenship. That case "squarely rejected the premise that anyone born in U.S. territory, no matter the circumstances, is automatically a citizen so long as the federal government can regulate them," Sauer wrote.

Experts on Native American law have questioned the government's reliance on that case,telling NBC Newsit was limited specifically to the unique status of tribes under U.S. law.

The American Civil Liberties Union, which is leading the legal challenge to Trump's executive order, responded in its brief that the text of the 14th Amendment is largely self-explanatory, as are the history and tradition of how it has been interpreted.

The group's lawyers also point to an 1898 Supreme Court ruling called United States v. Wong Kim Ark, which concluded that a man born in San Francisco to parents who were both from China was a U.S. citizen.

In addition to probing the language of the 14th Amendment, the justices may also examine whether the executive order falls afoul of a federal immigration law that usessimilar language, including "subject to the jurisdiction thereof." The court could rule that the executive order is unlawful under that law without having to decide the 14th Amendment question and put the onus on Congress to act.

The Supreme Court has a 6-3 conservative majority, whichrepeatedly ruled in Trump's favorlast year. But the court handed him amajor defeatin February when it ruled that his broad use of tariffs was unlawful.

Trump responded to that ruling withharsh criticismof the justices who voted against him in the 6-3 decision, calling them "disloyal to the Constitution."
