NEW YORK - A powerful nor’easter intensified its impacts across the East Coast Saturday, knocking out power to more than 100,000 homes and businesses and forcing airlines to cancel hundreds of flights.

Reuters reported that more than 119,000 utility customers were without electricity at one point Saturday as the storm affected a broad corridor stretching from Washington, D.C., through the Northeast and into Maine.

By 1:07 p.m. Eastern time, more than 88,000 customers remained without power across New Jersey, Connecticut, New York and Pennsylvania, according to PowerOutage.com data cited by Reuters.

Air travel was also significantly disrupted.

FlightAware reported approximately 425 flight cancellations involving U.S. airports Saturday, along with more than 1,300 delays as of the afternoon.

Storm affects major population corridor

The nor’easter is affecting one of the most heavily populated and traveled regions of the country.

The National Weather Service said coastal flooding, dangerous rip currents, strong wind gusts and heavy rain are expected from the Mid-Atlantic through New England through Monday.

The storm has affected communities from the Washington metropolitan area north through New Jersey, New York, Connecticut, Rhode Island and Massachusetts.

Coastal areas have faced some of the most severe conditions.

National Weather Service forecasters warned of multiple high-tide cycles capable of producing significant flooding in low-lying communities.

Power outages widespread

New Jersey, Connecticut and New York each had more than 25,000 utility customers without electricity shortly after 1 p.m. Saturday, according to Reuters.

PSEG Long Island reported approximately 13,300 customers without power and said crews had already restored service to more than 34,600 customers affected by the storm since Friday morning.

Utilities reported downed trees, branches and power lines as strong winds moved through the region.

Because many trees still have leaves in late September, forecasters warned they could catch more wind than during a typical winter nor’easter, increasing the risk of falling limbs and additional outages.

Flights canceled across Northeast

Airports throughout the Northeast experienced delays and cancellations Saturday as winds and heavy rain disrupted operations.

Boston Logan International Airport was among the facilities experiencing significant disruptions.

The Associated Press reported dozens of early cancellations at Logan and additional cancellations at New York’s John F. Kennedy International Airport.

Airlines including American Airlines, JetBlue and United Airlines had previously waived some change fees for passengers scheduled to travel through affected East Coast airports.

Travelers were urged to check directly with their airlines before leaving for airports.

Coastal flooding becomes major concern

The National Weather Service warned Saturday that the storm could produce major coastal flooding across portions of the Mid-Atlantic over multiple high-tide cycles.

Forecasters warned residents in low-lying coastal communities to prepare for roads becoming submerged and water reaching homes and businesses.

Flooding was already reported along parts of the New Jersey coast Saturday.

In Surf City, New Jersey, floodwater covered streets and entered some properties as the storm pushed water inland.

Officials in other coastal communities were preparing for additional flooding as the storm continued.

Strong winds batter coastline

Wind gusts along exposed portions of the coast were forecast to approach or exceed 60 miles per hour.

National Weather Service meteorologists said gusts on Cape Cod, Martha’s Vineyard and Nantucket could reach approximately 60 to 65 miles per hour.

Coastal portions of New Jersey, Delaware, Connecticut and Long Island were also expected to experience damaging wind gusts.

Those winds can bring down trees and power lines while making travel hazardous, particularly for high-profile vehicles.

Some bridges in Rhode Island restricted certain vehicles because of the wind.

Transportation disruptions extend beyond aviation

The weather also affected rail and ferry service.

Amtrak warned passengers about weather-related disruptions in the Northeast.

Ferry service connecting Cape Cod with Nantucket and Martha’s Vineyard experienced widespread cancellations because of high winds and rough seas.

Ferries serving Block Island in Rhode Island were also disrupted.

Officials urged travelers to verify schedules before attempting to travel.

States activate emergency measures

New York Gov. Kathy Hochul and New Jersey Gov. Mikie Sherrill declared states of emergency Friday in areas expected to experience significant storm impacts.

The declarations included New York City and other coastal communities.

Connecticut Gov. Ned Lamont activated the state’s Emergency Operations Center as officials prepared for power outages, flooding and wind damage.

Emergency officials continued monitoring conditions Saturday as the storm moved through the region.

Maryland and Mid-Atlantic impacts

The same storm had already disrupted events farther south along the Mid-Atlantic coast.

Organizers canceled the entire Oceans Calling Festival in Ocean City, Maryland, after high tides, flooding, strong winds and beach erosion made it unsafe to complete the festival site.

Coastal Maryland and Delaware have faced dangerous surf and flooding concerns as the nor’easter moves north.

The widespread impacts demonstrate the storm’s reach well beyond New England.

Storm expected to remain hazardous

Although conditions will vary by location, forecasters expect hazardous weather to continue into the remainder of the weekend.

The National Weather Service said coastal flooding, strong winds, heavy rain and dangerous surf could persist through Monday in parts of the Mid-Atlantic and Northeast.

Power restoration efforts are continuing while utilities prepare for the possibility of additional outages.

Airlines and other transportation providers are also continuing to adjust schedules as conditions evolve.

The American Desk will continue monitoring the storm as updated power-outage, travel and flooding information becomes available.
