A powerful Nor’easter—now being referred to as Winter Storm Hernando—has forced New York City into a rare standstill, with Mayor Zohran Mamdani issuing a sweeping Travel Ban as the storm barrels through the Northeast.
According to the BBC, the order, which took effect on February 22 and runs through midday on February 23, shuts down all non-emergency movement across city streets, highways, and bridges. Officials say the decision comes as snowfall intensifies and conditions rapidly deteriorate across the region.
“This will be something the likes of which we’ve not seen in years,” New York Governor Kathy Hochul said while announcing a statewide emergency declaration ahead of the storm’s arrival.
The Nor’easter has already delivered several inches of snow across parts of New York and New Jersey, with totals expected to climb significantly. Forecasts indicate snowfall rates could reach 2 to 3 inches per hour, with some areas projected to see 18 to 24 inches—and isolated totals nearing 28 inches—by the time the system moves out.
Meteorologists warn that the Travel Ban is tied directly to the storm’s intensity. According to the National Weather Service, conditions are expected to become “extremely treacherous,” with travel described as “nearly impossible” at peak snowfall.
The science behind Winter Storm Hernando explains why officials are taking aggressive action. Per NOAA, a Nor’easter forms when cold Arctic air collides with warm, moisture-rich air from the Atlantic Ocean, creating a powerful low-pressure system. In this case, that interaction has produced a fast-developing storm capable of heavy snow, high winds, and coastal flooding all at once.
“This is a large and impactful system affecting a densely populated region,” meteorologist Cody Snell said, noting it has been years since a storm of this scale hit the Northeast so broadly.
Wind gusts along coastal areas are expected to reach 65 to 70 miles per hour, increasing the risk of downed trees, power outages, and flooding in low-lying neighborhoods. Nearly 90,000 homes in New Jersey were already without electricity early Monday, with outages spreading across neighboring states.
Air travel has also taken a major hit. More than 5,500 flights were canceled on February 22, with thousands more grounded on February 23. New York’s major airports—including JFK and LaGuardia—have been among the hardest affected.
Beyond transportation, the Nor’easter has disrupted daily life across the city. Public schools are closed, Broadway performances were canceled, and major events—including scheduled horse races at Aqueduct Racetrack—have been called off.
The current storm marks the first blizzard warning issued for New York City in nearly a decade. It also represents the second major winter emergency under Mamdani’s administration, following a deadly cold snap earlier this year.
