The nor'easter is forming amid a suppressed Atlantic hurricane season due to El Niño, but unusually warm ocean waters — made 10-50 times more likely by climate change — are fueling the storm's intensity.
A powerful nor’easter storm on track to lash the East Coast this weekend is being fueled by climate change, according to scientists.
Even though a super El Niño climate pattern has suppressed hurricane formation in the Atlantic so far this year, the ocean’s exceptionally warm waters have helped the storm’s formation.
These water temperatures have been made 10-50 times more likely due to human-caused climate change, according to the non-profit Climate Central.
And it’s not just ocean temperatures that have been influenced. Rising sea levels and flooding linked to the storm are also exacerbated by climate change.
Delaware would only experience minor flooding from the nor’easter without sea level rise and New York City wouldn’t see flooding at all without climate change, the group said.
“Climate change is raising sea levels along the East Coast, so coastal communities are starting every storm from a higher water level,” Dr. Zachary Labe, a climate scientist at Climate Central, said in a statement.
“That makes flooding and erosion from nor’easters like this one more likely and more severe,” he added.
A wind gust of 52 mph was recorded on the north side of Long Island on Friday afternoon, according to The Weather Channel.
Coastal flooding is expected from the Mid-Atlantic up to New England, with some flooding already affecting parts of Virginia and North Carolina on Friday.
Rip currents are expected at beaches, and heavy rain and strong wind gusts will make travel difficult.
Ahead of the storm, states of emergency were declared by the governors of New York and New Jersey.
New York Gov. Kathy Hochul urged residents to “take this storm seriously” on social media, declaring an emergency for Nassau, Suffolk, New York City and Westchester.
“We’re expecting dangerous coastal flooding, strong winds and potential power outages through the weekend,” she said in a post on X.
In New York City, the annual Global Citizens Festival, featuring artists and celebrities including Lauryn Hill, John Legend, Shaboozey and Korean boy band Tomorrow X Together was cancelled and tickets were refunded.
Con Edison, New York City’s largest utility, said the energy company was “preparing additional crews to respond around the clock” in a post on X.
Notably, there are no lifeguards on duty at New York’s public beaches this weekend, because the season ended on September 13.
In neighboring New Jersey, Gov. Mikie Sherrill wrote on X that a state of emergency was effective starting at 5 p.m. in Atlantic, Burlington, Cape May, Cumberland, Middlesex, Monmouth, Ocean and Salem counties.
The state’s largest utility, PSE&G, also said its crews were prepared to work “24/7” to restore any service, should outages occur.
“As the storm’s track continues to evolve, the company has activated its storm response plan, positioned additional crews and resources throughout its service territory, alerted customers, and is prepared to respond safely and efficiently should severe weather cause power outages,” the company wrote in a release.
Impacts from the nor’easter are expected into next week, federal forecasters cautioned.
“In addition to the rain, wind gusts in excess of 50 mph are likely for eastern Long Island and southeastern New England, which will lead to power outages and tree damage in some areas,” the National Weather Service said.

Hurricane Polo intensified to Category 5 in the Pacific with 165 mph winds, expected to move slowly off Mexico's coast without making landfall but bringing heavy rain and flood risks to western Mexico through Thursday. Though weakening as it approaches Baja California, the storm may increase moisture and shower activity in the U.S. Southwest by mid-next week, raising concerns for localized flooding in Southern Arizona and Utah, following recent flash floods in south-central Arizona that stranded vehicles and required rescues.

Typhoon Dujuan neared Japan's eastern coast on Monday, bringing risks of floods and landslides, prompting flight cancellations by Japan Airlines and All Nippon Airways, suspending some railway services, postponing an equestrian event at the Asian Games in Aichi, shutting down the Tokyo Game Show, and leaving over 4,000 households in Chiba without power, with the Japan Meteorological Agency warning of potential record-breaking rainfall and linear rain bands over central Japan and Kanto.

Flooding rain is expected to threaten hundreds of millions across large parts of the U.S. over the weekend and into next week, starting with flood watches in the Southwest, Intermountain West and Midwest on Friday. The pattern is driven by an intensifying super El Niño and climate change, which are loading the atmosphere with moisture from record-warm Pacific waters. Heavy rain poses risks in burn scar areas of Idaho and Montana, with worsened flooding seen in wildfire-affected New Mexico and California. Three people, including a child, were killed on the Navajo Nation after being swept away in floodwaters, and three friends died earlier in August flash floods at Arizona’s Grand Canyon National Park. The threat shifts eastward by Saturday toward the Great Lakes and from Nebraska to Michigan, with potential impacts in Colorado’s Boulder area. Along the East Coast, showers could affect cities from Boston to the Carolinas into next week as a cold front brings storm chances Friday evening and Saturday morning.

Hurricane Lowell, a Category 3 storm in the Pacific, is approaching Hawaii with warnings of tornadoes, flash flooding, and destructive winds. Forecasters predict up to 360mm of rain and life-threatening surf, prompting emergency preparations on Kauai and Niihau as residents stock supplies and officials urge shelter-in-place measures.

Unseasonably hot spring temperatures in early September prompted fire bans in Queensland and New South Wales, with Brisbane recording its hottest September day since 2019. Strong winds fueled fire risks and caused jumping castle accidents in NSW and Victoria, injuring children and an infant. A cold front brought relief by Monday, with milder temperatures and showers expected across the east coast.

A severe thunderstorm struck Toronto on Wednesday, bringing torrential rain, strong winds, large hail, and flooding that damaged buildings, closed roads including the Don Valley Parkway, cut power to at least 45,000 customers, affected Michael Garron Hospital's emergency department, delayed or cancelled flights at Toronto Pearson, and prompted emergency operations activation by Mayor Olivia Chow.
