A slow-moving nor’easter pounded the U.S. Northeast from Saturday into Sunday, flooding New Jersey shore towns with each high tide, toppling trees on Long Island and in New York City and knocking out power to well over 100,000 customers at times, the Associated Press reported.

Leighton Brown, 56, a New York City Housing Authority maintenance worker, was killed Saturday when a tree fell on him in Brooklyn, according to the BBC and the New York Post (opens in new tab). The Post reported that he was working overtime at the Cypress Hills Houses, where residents knew him as “Mr. Fix-it,” and that the tree was one of several that came down in the development. The Guardian (opens in new tab), which did not name him, reported that the 56-year-old housing authority employee was struck in a parking lot and that police had not immediately determined whether wind brought the tree down.

New York Gov. Kathy Hochul declared a state of emergency for New York City’s five boroughs and Nassau, Suffolk and Westchester counties, and eight New Jersey counties were under an emergency declaration issued before the storm arrived, The Guardian (opens in new tab) reported. Parts of New Jersey received more than 4 inches of rain from Friday on, and residents told the AP that some places used to high water saw their worst flooding in close to a decade. A North Beach Haven shop owner said it was the worst she had seen in 10 years, and a Sea Bright homeowner credited rules adopted after Superstorm Sandy requiring homes to be raised with limiting the damage.

Outage estimates varied with the time of day. The BBC cited more than 160,000 households without power at one point, the AP said well over 100,000 customers were affected at times on Sunday, and The Guardian (opens in new tab) reported about 110,500 still without service Sunday afternoon, citing PowerOutage.us. More than 250 flights were canceled at Boston Logan International Airport by late Sunday morning as gusts reached about 40 mph, according to the Massachusetts Port Authority. The storm also canceled the Global Citizen Festival in Central Park and Ed Sheeran’s concert at Gillette Stadium, and the Red Sox moved their final game against the Cubs to Florida, the BBC reported.

By Monday the weakening storm was drifting away from the coast. Forecasters had expected Monday morning’s high tide to bring minor to moderate coastal flooding, less than over the weekend, and a coastal flood warning stayed in effect until 2 p.m. for much of the Jersey Shore, WPVI-TV reported. New Jersey Gov. Mikie Sherrill said in a social-media post Monday, quoted by CBS New York (opens in new tab), that some coastal and back-bay flooding could linger around the morning high tides and that a state of emergency remained in effect for eight counties. CBS New York (opens in new tab) reported that evacuations remained in place in parts of the state and that crews spent Monday pumping out floodwater in Allenhurst, where nearby Deal Lake had overflowed into the streets.

Monday’s coverage centered on cleanup rather than new flooding. U.S. Army Corps of Engineers contractors began measuring beach erosion in Ocean City, with surveys planned from Long Beach Island to Cape May this week, WPVI reported, and Rep. Frank Pallone asked state and federal agencies to survey the damage so New Jersey can seek recovery money, according to CBS New York (opens in new tab). WPVI said Tuesday morning’s high tide could also bring minor to moderate flooding. The AP reported that the storm could be the first of several along the East Coast this fall because of an El Niño pattern.
