A powerful nor'easter swept into the East Coast early Saturday, packing high winds and heavy rain across a corridor stretching from the mid-Atlantic to New England. By daybreak, thousands of households had lost electricity and hundreds of flights had been scratched from airline schedules, as the storm moved across the region with little sign of letting up.
The reach of the system was enormous. Tens of millions of people from the mid-Atlantic all the way to the coast of Maine found themselves inside the storm's path, a footprint that puts major cities, small towns, ports and coastal communities in the same warning zone. Forecasters said they expected significant winds and rain to continue throughout the weekend, meaning the danger was expected to linger well past the initial landfall of the system.
Coastal residents began preparing before the worst arrived. In one scene captured Friday as the storm's early stages moved in, John Garrisi and Gaige Graf carried an outdoor table away from the shorefront, a routine precaution taken by people who have learned that loose furniture and yard debris become missiles in a coastal storm. The photograph, by Associated Press photographer Robert F. Bukaty, captured the quiet preparation that precedes a storm's most destructive hours.
A nor'easter is a weather phenomenon distinct from a tropical cyclone, and understanding the difference matters for anyone trying to judge the risk. The storms form when powerful winds rotate around a low-pressure system offshore and, over time, shift to blow from the northeast toward the southwest. Because that wind direction pushes water and wave energy directly onto a coastline — rather than away from it — nor'easters can deliver the kind of prolonged coastal flooding, erosion and storm surge that a hurricane passing at a distance may not.
The combination of wind and water is what makes this kind of storm so disruptive. Sustained strong winds can topple trees onto power lines, snap utility poles and take down wires across entire neighborhoods at once. That is why outage totals tend to climb quickly once the storm arrives, and why electric utilities — often under pre-storm emergency orders — position repair crews in advance. Restoring power after a widespread wind event is slow work, because crews must clear debris before lines can be rebuilt, and every fallen branch can be a new outage.
Air travel is affected just as sharply. Hundreds of flights were cancelled as the storm moved through, a disruption that spreads far beyond the airports directly in its path. When weather grounds aircraft at a hub, the cancellations cascade: a plane that never arrives in New York is unavailable for an evening departure from somewhere else. Airlines typically also impose ground stops, holding departures for a period so the network can stabilize, which turns a regional weather problem into a national one.
Hurricane Nolo, a zig-zagging storm, is adding a second headache for forecasters, this time thousands of miles away in the Pacific. Satellite imagery captured Friday showed the hurricane approaching Hawaii's islands, and Nolo is expected to strengthen as it nears. Forecasters caution that it is likely to avoid making landfall, but they warn it will still bring dangerous flooding rains to the islands.
That distinction is the critical one for Hawaii. A storm that never crosses the coastline can still deliver a punishing rainfall event, and it is often the water — not the wind — that does the most damage. Saturating soils, swelling streams and overwhelming drainage systems can be disruptive even in areas well away from a storm's strongest core. Residents in the storm's path are advised to monitor rainfall forecasts closely, since the accumulation, not the track, determines how much flooding develops.
The two events underscore how busy the atmosphere is at this moment. On one coast, a mid-latitude windstorm is delivering wind, waves and surge; in the Pacific, a tropical cyclone is organizing near an island chain. The hazards differ substantially, which means the guidance differs too: coastal East Coast residents face a combination of flooding, erosion and outages, while Hawaii faces the risk of heavy rain over already vulnerable terrain.
The National Weather Service, the federal agency responsible for official forecasts, warnings and storm tracking, has both systems on its radar, along with local emergency managers who make staffing and evacuation decisions as each event unfolds.
For residents of the mid-Atlantic and New England, the message from Saturday's forecast is that the storm is only beginning to make its point. With rain and wind expected to persist through the weekend, the most dangerous hours may still be ahead, and the clean-up from Saturday's outages could stretch into Sunday. The national story began before dawn and, with a second storm bearing down on Hawaii, is unlikely to end with the weekend.
