The NWS described conditions as an 'unprecedented and expansive area of hazardous winter weather' from coast-to-coast

Much of the US was in the icy grip of an "unprecedented" winter storm Monday as frigid Arctic air sent temperatures plunging, forcing hundreds of flight cancellations, making driving hazardous and leaving millions without power in Texas.

Texas Governor Greg Abbott issued a disaster declaration for the southern state, and the National Weather Service (NWS) said more than 150 million Americans were under winter weather advisories.

"I urge all Texans to remain vigilant against the extremely harsh weather," Abbott said in a statement.

The NWS described conditions as an "unprecedented and expansive area of hazardous winter weather" from coast-to-coast.

More than 2.7 million people were without power in Texas, according to PowerOutage.US, and temperatures in the major metropolis of Houston dipped to minus 9°C.

"We woke up this morning, our pipes are all frozen and we have no water in the house," Burke Nixon, a resident of Houston, told AFP.

President Joe Biden issued an emergency declaration for Texas on Sunday providing federal assistance to supplement state relief efforts.

Texas is not used to such brutal winter weather, and the storm caused havoc in parts of the state, including a 100-car pile-up on Interstate 35 near Fort Worth last week that left at least six people dead.

"It's lovely to see the white but very dangerous at the same time because people here don't know how to drive in it. You know they're driving too fast," said Michael, a Houston resident who gave only his first name.

Austin-Bergstrom International Airport said that all flights had been cancelled on Monday due to the "historic weather," and Houston's George Bush Intercontinental Airport also shut down.

The NWS said Arctic air was driving a "polar plunge" that is expected to bring record-low temperatures.

Much of the US has been shivering under chilly temperatures for days, with about half of all Americans now under some sort of winter weather warning.

Temperatures have dropped across the country, with only parts of the southeast and southwest dodging it.

The cold snap has led to heavy snowfalls and ice storms that have caused a spike in electricity demand and power outages.

'Polar plunge'

Besides Texas, weather-related emergencies have also been declared in Alabama, Oregon, Oklahoma, Kansas, Kentucky and Mississippi. 

More than 300,000 customers are without power in Oregon. 

"Over 150 million Americans are currently under winter storm warnings, ice storm warnings, winter storm watches, or winter weather advisories as impactful winter weather continues from coast to coast," the NWS said.

"This impressive onslaught of wicked wintry weather across much of the Lower 48 [states] is due to the combination of strong Arctic high pressure supplying sub-freezing temperatures and an active storm track escorting waves of precipitation."

The NWS said record low temperatures were expected in much of the country.

"Hundreds of daily low maximum and minimum temperatures have been/will be broken during this prolonged 'polar plunge,' with some February and even all-time low temperature records in jeopardy," it said.

In a large area known as the southern Plains that spans parts of Texas, Oklahoma and Kansas, temperatures are expected to fall well below typical readings for the time of year. 

"Temperature anomalies are likely to be minus 3°C to 7°C below normal for much of the central and southern Plains," the NWS said.

It said six to 12 inches of snow were forecast from the Ohio Valley and eastern Great Lakes to northern New England.

Florida will remain the warmest spot in the continental United States, with highs above normal and temperatures generally around 26°C.

The extreme weather in the US triggered a massive blackout in northern Mexico that left some three million people without power, as natural gas supplies across the border were disrupted.

"Of the 4,766,901 users in the northern region of the country, 3,088,517 were affected and so far the electricity service has been restored to 65%," Mexico's Federal Electricity Commission announced on Twitter.

It said freezing gas pipelines had triggered "significant" cuts in gas supplies from the US, which affected local power plants that depend on the fuel in northern Mexico – itself suffering from plunging temperatures.
