Severe Arctic Blast to Hit the US

A severe Arctic blast is set to bring extreme cold to much of the United States, with the National Weather Service (NWS) issuing warnings across North Dakota, Minnesota, Montana, and Wisconsin. Temperatures are expected to plummet to subzero levels, with wind chills potentially reaching -25°F in some areas, posing risks of frostbite and hypothermia if precautions are not taken. The NWS has simplified its alert system, removing wind chill advisories in favor of Extreme Cold Watches and Warnings, which are issued when temperatures or wind chills fall below -4°F. This cold weather event is anticipated to extend to states as far south as Tennessee and Kentucky, with cold weather advisories likely in place. Residents are advised to prepare for the frigid conditions by dressing warmly, securing water pipes, and ensuring pets and vulnerable individuals are protected. Meanwhile, the UK is also experiencing a cold spell, with the UK Health Security Agency issuing alerts for potential health impacts due to lower temperatures.
