A powerful nor'easter is taking shape along the U.S. East Coast, and by late Friday night its first major effects were already visible: flooded streets and water pushing into homes in some New Jersey shore communities, while thousands of residents across the region were without electricity.
The storm arrived in stages. Its early stages were evident Friday, Sept. 25, along the rocky coastline of Gloucester, Mass., where surf broke heavy against the shore with the twin lighthouses of Thatcher Island visible offshore. Forecasters say the system is still building, and that the weekend — not Friday night — is expected to bring the worst of it.
According to the National Weather Service, tens of millions of people are in the storm's path, stretching from the Mid-Atlantic northward. The service said dangerous coastal flooding is the principal threat, concentrated especially along the waters of New Jersey and Delaware, where nor'easters routinely funnel wind-driven water inland and overwhelm drainage systems already saturated by earlier rain.
In the small New Jersey borough of Surf City, standing water covered streets Friday, its surface rippling with waves pushed in from the bay. Several homes were inundated, with water entering structures rather than merely pooling at the curb. Similar flooding was reported farther down the shore.
About 34 miles (54.7 kilometers) north in Manasquan, Mayor Mike Mangan said some roads were already underwater and warned residents not to expect a quick recede. He said he anticipated a lot of water in the streets "for a long time" — language that reflects how slowly floodwaters drain in low-lying barrier-island and river-estuary communities, where high water is pushed inland and can remain once the winds shift. A voluntary evacuation had been issued earlier for some low-lying sections of the borough, a step taken before conditions had visibly deteriorated.
Those early evacuation calls were among the first signs that officials in the region were preparing for a serious event rather than a routine autumn storm. In Sea Bright, a barrier-island beach community at the northern end of the Monmouth County coast, Mayor Brian Kelly said the borough was bracing for sustained winds of up to 50 mph (80 kph) and flooding that could reach as much as 6 feet (1.8 meters) on some streets. He said officials expect the water to begin arriving Saturday and to worsen by midday, meaning residents would face the worst of the storm with little daylight left to act.
Kelly compared the coming flooding with the community's typical experience, noting that Sea Bright sees only one or two significant flooding events in a given year — sometimes more, sometimes fewer. This time, he said, he believes it will be substantially worse than that norm, and likened the potential impact to the 2011 storm known as Irene, which produced major flooding across the Northeast. He cautioned that he hopes his assessment is wrong, but said it was his honest expectation based on the setup.
His focus, however, was less on the forecast totals than on getting people out of harm's way. Kelly urged the hundreds of residents living in Sea Bright's lowest-lying areas to seriously consider evacuating ahead of Saturday, and said the town would open up for those who decide to leave. The appeal reflects a recurring theme in coastal storm coverage: officials cannot prevent the water, but they can reduce the number of people in it when the surge arrives.
The storm's effects were being felt well beyond the water's edge. Concerts were canceled, and dozens of flights bound for Boston, Nantucket and Martha's Vineyard were scrapped on Friday and Saturday. Several major airlines said they would waive change and cancellation fees on a range of East Coast flights through the weekend, a gesture that typically signals carriers anticipating a high volume of cancellations and misrouted passengers extending well past the storm's duration.
Electricity losses added to the disruption. Thousands of homes and businesses across the East Coast were in the dark late Friday, a number officials and utility planners generally expect to climb as the storm intensifies overnight and into Saturday morning. Outages of that scale complicate emergency response, since residents lose refrigeration, heating, medical-device power and access to news and weather alerts at exactly the moment conditions turn most dangerous.
For meteorologists, nor'easters are a familiar but unpredictable threat. The storms form offshore and rotate counterclockwise, driving wind and ocean water from the northeast into the coastline at a near-right angle — a geometry that maximizes the volume of water pushed toward shore. Because the system's impact depends on the precise track and timing of its strongest phase, officials are careful to speak of ranges rather than single numbers, and to reserve worst-case language for areas that fall squarely within the storm's most dangerous sector.
That uncertainty is why communities such as Sea Bright, Surf City and Manasquan are balancing evacuation requests against the disruption of leaving, and why transportation networks from Boston to the islands are shutting down two days before the weather is expected to peak. The message from officials is consistent even as the numbers shift: conditions will deteriorate through Saturday, the highest water is expected around midday, and the danger comes not from wind alone but from water moving ashore into streets, homes and evacuation routes.
