Historic winter storm kills at least 10 across US

WASHINGTON – A monster storm barrelling across swathes of the US has killed at least 10 people and prompted warnings to stay off the roads, and caused mass flight cancellations and

power outages

, as freezing conditions persisted into Jan 26.

As the storm dumped snow, sleet and freezing rain across the wide expanse, officials cautioned that an Arctic air mass behind the system would see temperatures fall dangerously low for days, prolonging disruptions to daily life.

The US National Weather Service (NWS) told Americans to expect more of the same weather conditions into the morning of Jan 26.

New York Mayor Zohran Mamdani said five people were found dead outside over the weekend in freezing temperatures. While he did not confirm the deaths were weather-related, he told reporters “there is no more powerful reminder of the danger of extreme cold”.

In Texas, the authorities confirmed three deaths, including a 16-year-old girl killed in a sledding accident.

Two people died in Louisiana from hypothermia, the southern state’s health department said.

The PowerOutage.com tracking site showed more than 840,000 customers without electricity as of the night on Jan 25, mostly in the US South where the storm intensified on Jan 24.

In Tennessee, where a band of ice has downed power lines, more than 300,000 residential and commercial customers were without electricity, while Louisiana, Mississippi and Georgia – where such storms are less common – each had over 100,000 outages.

The outages are particularly dangerous as the South is being walloped by treacherous cold that the NWS warns could set records.

The authorities from Texas to North Carolina and New York urged residents to stay home due to the perilous conditions.

“Stay off the roads unless absolutely necessary,” Texas’s Emergency Management Division posted on X.

The storm was moving on Jan 25 into the north-east, dumping snow and sleet on heavily populated cities including Philadelphia, New York and Boston.

At least 20 states and the US capital Washington have declared states of emergency.

Residents in the capital Washington awoke to a blanket of several inches of snow on sidewalks and roads, followed by heavy sleet.

Federal offices have been pre-emptively closed for Jan 26.

Several major airports in Washington, Philadelphia and New York had nearly all flights cancelled for the day.

Tracking site Flightaware.com showed more than 19,000 flights into and out of the country

had been scrapped since

Jan 24

.

US President Donald Trump, who was riding out the storm at the White House, said on his Truth Social platform on Jan 24: “We will continue to monitor, and stay in touch with all States in the path of this storm. Stay Safe, and Stay Warm!”

Polar vortex

The brutal storm system is the result of a stretched polar vortex, an Arctic region of cold, low-pressure air that normally forms a relatively compact, circular system but sometimes morphs into a more oval shape, sending cold air spilling across North America.

Scientists say the increasing frequency of such disruptions may be linked to climate change, though the debate is not settled and natural variability plays a role.

But Mr Trump – who scoffs at climate change science and has rolled back green energy policies – questioned how the cold front fit into broader climatic shifts.

“WHATEVER HAPPENED TO GLOBAL WARMING???“ the Republican leader posted.

The NWS warned that heavy ice could cause “long-duration power outages, extensive tree damage, and extremely dangerous or impassable travel conditions”, including in many states less accustomed to intense winter weather.

The authorities warned of life-threatening cold that could last a week post-storm, especially in the Northern Plains and Upper Midwest, where wind chill lows were forecast to dip to extremes under minus 45 deg C.

Such temperatures can cause frostbite within minutes. AFP
