A dangerous polar-vortex weather system is bringing extreme low temperatures to large parts of the US this week, with authorities warning residents about hypothermia and frostbite, thousands of flights canceled, and at least two people already dead in connection with the cold.
This week, regions from North Dakota into Missouri, and as far east as upstate New York, are expected to drop to about 50 degrees below average for late January, The Washington Post reported Monday.
Weather forecasters and doctors have warned of cold and wind so intense that it could give people frostbite within five minutes of exposure.
This map shows the lowest that windchills are expected to fall this week. Windchill figures are adjusted down from actual temperatures to reflect that strong wind removes heat much faster than still air.
The polar vortex refers to an air pattern that keeps cold air in the polar regions.
Sometimes, that mass of air expands and get pushed away from its normal pattern, in this case allowing cold air from the North Pole to pour over the US.
President Donald Trump, who has long questioned the science behind climate change, spoke sarcastically of the cold on Twitter on Monday.
“What the hell is going on with Global Waming? Please come back fast, we need you!” he tweeted. Weather and climate are two different things: Weather on one day or even over a longer period in one large location doesn’t define the global climate.
“A single cold snap in one part of the world does nothing to invalidate the long-term trends,” Andrew Freedman of the news website Axios tweeted.
Under-25s ‘never felt this cold before’
Forecasters predict a high of minus 14 degrees Fahrenheit (minus 26 degrees Celsius) in the northern cities of Chicago and Minneapolis on Wednesday, The New York Times reported Monday.
hicago could see a low of minus 29 (minus 34 Celsius), The Washington Post added. This would surpass the city’s coldest recorded temperature of minus 27 on January 20, 1985, according to the National Weather Service.
Windchills could hit minus 50 (minus 45.6 Celsius) in Chicago and minus 60 (minus 51 Celsius) in Minneapolis that same day, The Times added.
Americans who are 25 or younger will have “never felt this cold before,” the CNN meteorologist Tom Sater said.
Frostbite in less than 5 minutes
Experts say residents could contract frostbite and hypothermia from even very brief exposure to the elements.
“You’re talking about frostbite and hypothermia issues very quickly, like in a matter of minutes, maybe seconds,” Brian Hurley, a meteorologist at the Weather Prediction Center, told the Associated Press.
The lack of blood circulation to hands and feet can cause frostbite. Hypothermia occurs when the body is exposed to extremely cold conditions over a prolonged period, and as a result the body temperature becomes dangerously low.
The National Weather Service’s Chicago office warned that “dangerously cold wind chills could cause frostbite on exposed skin in as little as 5 minutes.”
Amanda Jackson, an emergency-room doctor at SSM Health St. Mary’s Hospital in Madison, Wisconsin, also told the local Channel 3000 newsthat people with exposed skin could see signs of frostbite — “a tingling sensation and then a throbbing pain” — in less than five minutes.
Eric Ernest, a doctor at the Nebraska Medicine Emergency Department,told Omaha’s local WOWT 6 News that people could incur frostbite “anywhere from 10 to 20 minutes of exposed skin.”
A 22-year-old man in Rochester, Minnesota, was found dead amid cold temperatures outside his relatives’ house, to which he didn’t have a key, the local KIMT 3 News reported. Authorities believe he suffered from frostbite and hypothermia, though an autopsy has not yet been carried out.
The police found blood smeared on several doors and footprints that suggested that he fell multiple times. Officers also found clothing near the house, seeming to confirm the hypothermia theory — people in the final stages of hypothermia can feel irrationally hot and take their clothes off.
Two deaths have already been reported in connection with the cold weather this week, CNN said.
Classes and flights canceled
Nearly 2,300 flights have already been canceled, with another 11,800 delayed, Reuters reported.
American Airlines, United Airlines, JetBlue Airways, Delta Air Lines, and Spirit Airlines have waived flight change fees from the Midwest and the Northeastern to accommodate for the weather, CNBC reported. Southwest Airlines said people could delay their flights from up to two weeks later without having to pay the fare difference.
The city of Peoria, Illinois, closed all public schools and canceled trash collections on Wednesday because of the cold weather and snow.
Public schools in Milwaukee also closed on Tuesday and in Chicago on Wednesday.
‘All hands are on deck’
Chicago has opened community centers, libraries, and police stations as warming centers. Mayor Rahm Emanuel told The New York Times he was working with local officials to help homeless people living alongside highways, adding: “All hands are on deck.”
