CHICAGO, Jan 30, 2019 (BSS/AFP) – Tens of millions of people in the United
States are bracing for a potentially life-threatening deep arctic chill
forecast to hit swaths of the country on Wednesday.
Companies have told their workers to stay home, schools are closed and
hundreds of flights have been canceled.
The US Postal Service — known for its commitment to bringing the mail
whatever the weather — has even reportedly suspended deliveries in Iowa due
to the severe cold.
Temperatures in almost a dozen states stretching more than 1,200 miles
(1,930 kilometers) from the Dakotas to Ohio were forecast to be the coldest
in a generation, if not on record.
“One of the coldest arctic air mass intrusions in recent memory is surging
south into the Upper Midwest before spreading across much of the eastern two-
thirds of the country,” the National Weather Service said.
“Expect frigid temperatures, bitterly cold and life-threatening wind
chills, likely leading to widespread record lows and low maximum temperatures
from the Upper Midwest to the Great Lakes and Ohio Valley.”
The cause is a swirl of arctic air that broke away from the polar vortex
that usually encircles the North Pole.
The National Weather Service forecast temperatures between -10 to -40
degrees Fahrenheit (-23 to -40 Celsius) by Wednesday across the Midwest, with
wind chills making it seem as cold as -65 degrees Fahrenheit in one area of
Minnesota.
Chicago, America’s third largest city, was expected to be colder than parts
of Antarctica.
Authorities in Illinois, Michigan and Wisconsin put emergency measures in
place to handle the frigid weather.
“We need everyone to do your part and make sure you and your families are
prepared,” said Illinois Governor JB Pritzker.
– Frostbite warnings –
Americans were asked to stay home if possible Wednesday, when temperatures
are expected to be at their coldest.
Scores of schools, businesses and government agencies announced closures in
multiple states.
“People exposed to extreme cold are susceptible to frostbite in a matter
of minutes,” warned the NWS.
Lawrence Gottlieb of the University of Chicago Medical Center said the
threat was significant “when temps fall below zero, especially when there is
a strong wind.” Some 160 warming centers were opened in Chicago, where
temperatures could potentially equal or exceed the all-time record of -27
degrees Fahrenheit. With the wind chill, it would feel like -40 or -50,
officials said.
“They are life-threatening conditions and temperatures,” Chicago Mayor Rahm
Emanuel told a news conference.
In Minneapolis, officials allowed residents to stay on public buses and
trains for warmth.
– Snow storm –
In the northeastern and southern United States, snow was falling.
A cold emergency was declared in the US capital Washington, with additional
services put on for the homeless.
In Atlanta, some 300 flights were canceled Tuesday as the city prepares for
the Super Bowl and more than 400 were canceled in Chicago, a major regional
hub for US airlines.
In Canada, the icy temperatures — stretching from Manitoba in the western
Prairies region to the Atlantic seaboard — prompted a rare “hazardous” cold
warning from the government.
Environment Canada reported record-breaking snowfall at the Ottawa airport,
where some 50 flights were canceled, with an accumulation of nearly a meter
(more than three feet).
An additional 200 flights were canceled at Toronto’s airport.
– Global warming? –
Scientists say climate change is causing more extreme weather, and one
theory for polar vortex chills is that arctic air currents usually trapped
around the North Pole are weakened and dislodged by a warming climate.
President Donald Trump used the occasion to again voice skepticism about
climate change, tweeting: “What the hell is going on with Global Waming?
(sic) Please come back fast, we need you!”
But the National Oceanic and Atmospheric Administration, which operates
NWS, tweeted, “Winter storms don’t prove that global warming isn’t
happening,” with a link to a 2015 explanatory article.
