A powerful snowstorm has paralyzed large parts of the United States, leaving at least 10 people dead and causing widespread disruption from Texas to New England. The storm forced the closure of schools and roads nationwide, canceled thousands of flights, and left millions without electricity. The U.S. National Weather Service said conditions were unlikely to improve before Monday morning and urged residents to stay indoors unless absolutely necessary.

According to reports, two people in Louisiana died from hypothermia, while one person died in Texas. New York City Mayor Zohran Mamdani said five deaths occurred over the weekend, though it was unclear if they were weather-related. Major U.S. media outlets, citing the National Weather Service, reported that heavy snow covered most of 15 states, including Illinois, Ohio, Indiana, Kansas, New Jersey, New York, Pennsylvania, Missouri, Oklahoma, Texas, and Tennessee. Freezing rain also hit the Carolinas and mid-Atlantic states, placing about 185 million people under winter weather alerts.

Airlines canceled around 11,000 flights scheduled for Sunday, and more than 900,000 customers lost power, including 250,000 in Tennessee.
