New York City Mayor Zohran Mamdani declared a state of emergency and issued a temporary travel ban for the metropolis starting Sunday evening, October 21:00 local time, until Monday midday, in anticipation of a severe winter storm. The ban prohibits all traffic, including cars, trucks, scooters, and e-bikes, on streets, highways, and bridges, with exceptions for essential personnel and emergency services. This storm, which is expected to bring between 45 and over 70 centimeters of snow, is the most significant the city has experienced in a decade. Winter storm warnings have been issued for New York and at least six other states along the East Coast, with potential coastal flooding also predicted.
