A massive winter storm is poised to grip the United States, threatening over 160 million people. The "extremely dangerous" conditions, including heavy snow and freezing rain, are expected to begin Friday. The National Weather Service (NWS) issued warnings about the Arctic blast.

The storm will track east from the High Plains and Rockies. Cities from Memphis to New York City are in the storm's path. Heavy snow is predicted for the Southern Rockies and Plains, extending into the Mid-Atlantic and Northeast.

US transportation officials are bracing for widespread travel disruption. Airports in major cities warned of potential delays and cancellations. The NWS cautioned about life-threatening risks of hypothermia and frostbite due to sub-zero temperatures and wind chills.

Winter storms are a recurring challenge in North America, impacting infrastructure and daily life. Similar weather patterns have caused disruptions in other northern hemisphere countries, highlighting the global impact of extreme weather events.

The storm is expected to continue its eastward movement. Residents are urged to monitor weather updates and heed safety advisories.
