WASHINGTON: Travel misery was set to continue Sunday as a powerful snowstorm blasted southern US states, bringing subzero temperatures to regions not accustomed to the deadly winter conditions.

The latest bout of extreme weather came about a week after a monster storm pummeled a wide swath of the United States, killing more than 100 people and leaving many communities struggling to dig out from snow and ice.

Heavy snow fell in North Carolina and neighbouring states Saturday, as authorities urged residents to stay off the roads and warned oceanfront structures were threatened by the storm.

All of North and South Carolina, and portions of Georgia, eastern Tennessee and Kentucky, as well as southern Virginia were under a winter storm warning.

North Carolina saw 750 car crashes on Saturday, the highway patrol said.

Faust, North Carolina recorded 14.5 inches (37 cm) of snow, while West Critz, Virginia got 12.5 inches. Harrisburg, Tennessee received more than nine inches of accumulation.

In the North Carolina town of Cape Carteret, high winds sent thick snow blowing sideways, prompting the National Weather Service to warn that travel was “Treacherous and Potentially Life-Threatening especially if you become stranded.”

In dramatic footage released by police in Gastonia, North Carolina, a train ploughed at high speed into a semi-truck that had gotten stuck on the tracks, crushing the vehicle. No one was hurt.

The weekend storm forced more than 1,800 flight cancellations Saturday and Sunday at Charlotte Douglas International Airport in North Carolina, a major hub for American Airlines, data from the tracker FlightAware showed.

A 300-strong “snow team” was working to clear runways, taxiways, roads and sidewalks, the airport said Saturday.

More than 600 flights were cancelled Saturday at Atlanta’s international airport, the world’s busiest. About 50 flights in and out of Atlanta were cancelled in the early hours of Sunday.

“An explosively deepening coastal cyclone will continue to bring moderate to heavy snow, high winds, and possibly blizzard conditions for the Carolinas,” the National Weather Service said Saturday.

“An intense surge of arctic air behind the coastal storm will send below freezing temperatures down toward South Florida by Sunday morning.”

Davis, West Virginia recorded the lowest temperature in the lower 48 states on Saturday — a frigid minus 28°F (minus 33°C).

About 156,000 customers remained without power early Sunday, mostly in the south, according to poweroutage.us, with Mississippi, Tennessee and Louisiana hardest hit.

In North Carolina, the National Park Service announced the closure of campgrounds and some beaches at the Outer Banks, a series of barrier islands off the coast of the southern state that are vulnerable to storms.

It said oceanfront structures were threatened, and a section of highway that threads through its dunes was closed.

In Mississippi, Governor Tate Reeves said the US Army Corps of Engineers helped to install generators at critical sites, and authorities were opening 79 shelters and warming centres across the state.

The freezing weather forced Nasa to postpone a key fueling test over the weekend of the 322-foot (98-metre) rocket that is on the Cape Canaveral launch pad in Florida.

That in turn is likely to push back by at least a couple of days a planned manned Moon flyby slated for this month.

US President Donald Trump has said India will buy Venezuelan oil, as opposed to purchasing oil from Iran.

“We’ve already made that deal, the concept of the deal,” Trump told reporters aboard Air Force One as he travelled to his vacation home in Florida from Washington.

Reuters reported on Friday that the United States has told Delhi it could soon resume purchases of Venezuelan oil to help replace imports of Russian oil, citing three people familiar with the matter.

India has not been importing significant amounts of Iranian oil due to US sanctions, but became a major buyer of Russian oil after Russia’s invasion of Ukraine in 2022 triggered Western sanctions that drove down its price.

Trump in August doubled duties on imports from India to 50% to pressure New Delhi to stop buying Russian oil, and earlier this month said the rate could rise again if it did not curb its purchases.

However, Treasury Secretary Scott Bessent signaled in January that the additional 25% tariff on Indian goods could be removed, given what he called a sharp reduction in Indian imports of Russian oil.

Trump in March 2025 also imposed a 25% tariff on countries buying Venezuelan oil, including India. The US government this week lifted some sanctions on Venezuela’s oil industry to make it easier for US companies to sell its crude oil.

Trump’s comments on Saturday appeared to reflect continued improvement in US-India relations, which have been tense throughout the past year.

Trump also said China could make a deal with the US to buy Venezuelan oil.

“China is welcome to come in and would make a great deal on oil,” Trump said, without providing any details.

• New START expires Thursday unless an extension happens.
• President Putin proposes a one-year rollover in September.
• Treaty caps 1,550 deployed strategic warheads and 800 launchers.

WASHINGTON: Come Thursday, barring a last-minute change, the final treaty in the world that restricted nuclear weapon deployment will be over.

New START, the last nuclear treaty between Washington and Moscow after decades of agreements dating to the Cold War, is set to expire, and with it restrictions on the two top nuclear powers.

The expiration comes as President Donald Trump, vowing “America First,” smashes through international agreements that limit the United States, although in the case of New START, the issue may more be inertia than ideology.

Russian President Vladimir Putin in September suggested a one-year extension of New START.

Trump, asked afterward by a reporter for a reaction while he was boarding his helicopter, said an extension “sounds like a good idea to me” — but little has been heard since.

Putin ally Dmitry Medvedev, who as Russia’s president signed New START with counterpart Barack Obama in 2010, said in a recent interview with the Kommersant newspaper that Russia has received no “substantive reaction” on New START but was still giving time to Trump.

A White House official said on condition of anonymity that Trump would like to see “limits on nuclear weapons and involve China in arms control talks.”

The way to do that, the official said, Trump “will clarify on his own timeline.”

Daryl Kimball, executive director of the Arms Control Association, which supports reducing nuclear risks, said Trump’s second administration, which has sidelined career diplomats and entrusted decision-making only to a handful of people, is not functioning in a normal way that would allow complex negotiations.

Trump “seems to have the right instinct on this issue but has thus far failed to follow through with a coherent strategy,” Kimball said.

Jon Wolfsthal, director of global risk at the Federation of American Scientists, said Trump and Putin could pick up the phone and agree immediately at a political level to extend New START.

“This is a piece of low-hanging fruit that the Trump administration should have seized months ago,” he said.

Wolfsthal is among experts involved in the “Doomsday Clock” meant to symbolise how near humanity is to destruction. It was recently moved closer to midnight in part due to New START’s demise.

‘Empty formality’?

Trump called in October for the United States to resume nuclear testing for the first time in more than 30 years, although it is not clear he will carry it out.

Russia in 2023 already suspended a key element of New START, allowing inspections, as relations deteriorated sharply with US President Joe Biden’s administration over Russia’s invasion of Ukraine.

Alexander Khramchikhin, a Russian military analyst, said the two powers already had indicated they will do as they like.

“It’s clear that the treaty has reached its end,” he said. “It’s just an empty formality that will disappear.”

Vassily Kashin, director of the Center for Comprehensive European and International Studies in Moscow, said Russia would watch if the United States ramps up its nuclear arsenal and, if so, would decide measures in response.

“But if the Americans don’t take any drastic measures, such as installing warheads, Russia will most likely simply wait, observe and remain silent,” he said.

China factor

New START restricted Russia and the United States to a maximum of 1,550 deployed strategic nuclear warheads each — a reduction of nearly 30% from the previous limit set in 2002.

It also limits launchers and heavy bombers to 800 each, although the number is still easily enough to destroy Earth.

During his first term, also faced with New START’s expiration, Trump insisted a new treaty bring in China — whose arsenal is fast growing, although well below the other two powers. A US negotiator even provocatively put an empty chair with a Chinese flag.

Biden on taking office in 2021 quickly agreed to extend New START by five years to 2026.

Despite his stance on New START, Trump has enthusiastically restarted diplomacy with Russia that Biden cut off over the war, inviting Putin to an August summit in Alaska and unsuccessfully trying to broker a deal in Ukraine.

US allies France and Britain also have established nuclear arsenals on a smaller scale, while Pakistan, India, Israel and North Korea have known nuclear weapons but are not part of international agreements.
