Nearly 110 million under wind chill warnings, advisories as ‘Arctic blast’ grips US

Nearly 110 million people were under wind chill advisories or warnings, as of Sunday afternoon, as much of the country prepares for freezing temperatures and wind chills as a result of an Arctic blast approaching from the north.

The National Weather Service (NWS) warned of “dangerously cold wind chills” and of temperatures about 25 to 40 degrees below average from the Northern Rockies to the Plains, Middle Mississippi Valley, and Ohio Valley.

The blast is expected to bring snow downwind from the Lower Great Lakes and will bring snow from parts of the Lower Mississippi Valley to the Northeast, the NWS said in its forecast, also warning of freezing rain over parts of the Southern Plains to the Southern Appalachians.

There were 109.13 million people under wind chill advisories or warnings as of Sunday afternoon, according to the NWS.

For those under a wind chill warning, the NWS warns that just 10 minutes outside could cause frostbite on exposed skin. A wind chill advisory means frostbite could develop after 20 minutes.

The NWS, in its wind chill warning, tells people to “avoid outside activities if possible,” but, in its advisory, the NWS instructs people to “use caution while traveling outside.
