A powerful nor'easter swept into the East Coast in the early hours of Saturday, packing high winds, driving rain against the shoreline and leaving thousands of households without electricity. By daybreak, regional and major airlines had already scratched hundreds of flights, and forecasters warned that the worst of the weather was not yet in. Tens of millions of residents from the mid-Atlantic through the coast of Maine sit inside the storm's path, and officials cautioned that significant wind and rain would continue through the weekend.
The early stages of the storm were visible along exposed waterfronts, where residents were hauling patio furniture and other loose objects away from the surf. In a photograph from the early hours of the storm, John Garrisi and Gaige Graf carried an outdoor table inland from a shorefront property, one of countless small precautions taken by coastal residents bracing for a system forecast to deliver a prolonged blast of wind and water. The image, by Robert F. Bukaty for The Associated Press, captured the pattern seen up and down the coast: securing property early, before conditions deteriorate.
A nor'easter is a powerful storm whose defining feature is the direction of its wind. Rather than tracking across the country, a low-pressure system develops over the warm waters of the Atlantic and intensifies as it moves northward, drawing cold air down from the interior and driving winds in from the northeast. That wind, amplified by a pressure gradient between the storm and a high-pressure ridge to the west, is what gives the phenomenon its name — and it is what makes the system so punishing, since the strongest gusts arrive from the direction that has open ocean to build strength over.
The timing is not unusual. Nor'easters are a hallmark of the autumn season, becoming most common from September into early October, when the contrast between Arctic air masses and still-warm ocean water is greatest. A storm of this kind typically intensifies as it tracks up the coast, meaning the Mid-Atlantic often sees the leading edge of wind and heavy rain while New England endures the most sustained pressure, with Massachusetts, Rhode Island, Maine and the coastal waters between them bearing the brunt later in the event.
The first tangible effects have been transportation and utility casualties. Thousands of people lost power as lines were brought down by wind-blown branches and, in some places, by trees that toppled outright. Utility crews, which typically stage extra teams and equipment ahead of a forecast of this magnitude, will face long restoration timelines because access to downed lines is difficult in saturated, storm-damaged terrain. Away from homes, hundreds of flights were cancelled, disrupting the plans of passengers on routes that pass through the affected corridor and stranding travelers at airports where ground crews and de-icing or de-watering operations cannot keep pace.
Along the coast, the combination of onshore wind and rising seas is the primary hazard. Storm surge and battering waves can overtop sea walls and flood low-lying streets, particularly in the hours around high tide, while the heaviest surf is forecast to hit barrier beaches, lighthouses and harbor entrances. Shoreline communities are typically urged to avoid floodwaters, which can hide dangerous currents and wash out roadway surfaces, and to stay clear of the surf during high-wave periods even where conditions appear manageable.
The National Weather Service, the federal agency responsible for watches, warnings and advisories, has been the lead source of guidance, and its warnings have covered the full breadth of hazards — from wind gusts capable of downing trees, to coastal flood inundation, to rainfall that can overwhelm drainage systems in already-saturated urban areas. Forecasters expect the storm to deliver not a single burst of severe weather but a multi-day siege, with a foot or more of wind-driven rain in some coastal locations and no let-up until the weekend's end.
A second system is unfolding thousands of miles away, giving forecasters two simultaneous crises to track. Hurricane Nolo, a zig-zagging storm, is approaching Hawaii, and satellite imagery captured Friday showed the system approaching the islands as it strengthened. Nolo is expected to avoid making landfall, but forecasters warn that it will still bring dangerous flooding rains, a hazard that can turn quickly — especially over steep volcanic terrain and in low-lying valleys where water does not drain well.
The pairing is a reminder of how broad the current stretch of severe weather has become. Coastal residents from Virginia to Maine are dealing with a windstorm, while Hawaiian officials are preparing for a strengthening hurricane that threatens heavy rain even without a direct hit. Emergency planners, utility companies and airlines servicing both regions are effectively running two large operations at once, and any additional development in the tropics could complicate that picture further.
For residents, the practical guidance issued ahead of both storms is largely unchanged: charge phones and power banks before conditions worsen, secure loose objects on patios and balconies, keep a flashlight and spare batteries on hand, and check on elderly neighbors or relatives who may be in areas prone to flooding. Travelers should confirm itineraries directly with carriers rather than relying on departure boards, and avoid driving through standing water.
The weekend ahead, forecasters say, is expected to remain unsettled. With significant winds and rain in the forecast through the end of the weekend and repair crews working around the clock, the scope of the damage — and the return date of cancelled flights — will likely not be clear until the storm has fully moved through.
