A powerful snowstorm has caused widespread disruption across the United States, leaving at least 30 people dead and millions without electricity. The storm has led to the cancellation of thousands of flights and prompted weather-related emergency declarations in at least 25 states, according to the Associated Press. The extreme cold and heavy snowfall have affected areas from New York and Massachusetts in the northeast to Texas and North Carolina in the south.

Snowfall reached up to 18 inches in some regions, with temperatures dropping to minus 18 degrees Celsius. The storm directly impacted about 118 million people, while more than 150 million were advised to remain cautious. New York reported the highest number of fatalities, with five deaths. Governor Kathy Hochul deployed the National Guard in New York City, and Mayor Zohran Mamdani urged residents to assist those in need. Deaths were also reported in Tennessee, Louisiana, Texas, Massachusetts, and Kansas.

The U.S. National Weather Service said the storm’s main system was moving toward the Atlantic Ocean but warned that new Arctic air could bring more snow and rain to the northeast in the coming days.
