Historic winter storm kills at least 10 across US

A monster storm barreling across swathes of the United States has killed at least 10 people and prompted warnings to stay off the roads, mass flight cancelations and power outages, as freezing conditions persisted into Monday. As the storm dumped snow, sleet and freezing rain across the wide expanse, officials cautioned that an Arctic air mass behind the system would see temperatures fall dangerously low for days, prolonging disruptions to daily life. New York Mayor Zohran Mamdani said five people were found dead outside over the weekend in freezing temperatures. While he did not confirm the deaths were weather-related, he told reporters "there is no more powerful reminder of the danger of extreme cold."
