New York City has entered a state of emergency after Mayor Zohran Mamdani ordered a sweeping shutdown of the city’s traffic network in response to a powerful winter storm. As reported by The Associated Press, the order restricts travel across streets, highways and bridges except for emergency and essential purposes. The shutdown began Sunday night and is set to remain in effect through midday Monday as officials respond to what meteorologists describe as a major nor’easter.
The National Weather Service warned that snowfall rates could reach three inches per hour, with total accumulations of up to 24 inches in some areas. Wind gusts near 60 miles per hour are expected to create whiteout conditions and increase the risk of coastal flooding and power outages. Blizzard warnings extend beyond New York to Long Island, Boston and several northeastern states, with tens of thousands already without electricity in neighbouring New Jersey.
Mayor Mamdani said the city has not faced a storm of this magnitude in nearly a decade, urging residents to avoid nonessential travel. Essential workers remain exempt from the restrictions. By Sunday evening, visibility had sharply deteriorated, and parts of Manhattan’s skyline were barely visible from Brooklyn as heavy snow intensified. Some residents expressed concern about workplaces remaining open despite widespread transit suspensions.
The aggressive shutdown mirrors emergency responses often seen in major Canadian cities during severe winter events. In Toronto and Montreal, municipal governments routinely declare snow emergencies that restrict parking, close major roads and deploy large scale snow removal fleets when accumulation thresholds are met. Canadian cities also rely heavily on coordinated provincial and federal weather alerts, similar to the U.S. system, to guide closures of schools, public transit and government offices. However, due to more frequent exposure to heavy snowfall, Canadian infrastructure is generally built with higher winter resilience, often allowing core transit services to continue operating even during major storms.
As climate patterns bring more extreme weather events across North America, the New York shutdown highlights how large urban centres on both sides of the border are adapting emergency protocols to balance public safety, economic disruption and infrastructure capacity during severe winter conditions.
