Super El Niño's 'Off the Charts' Strength Could Alter US Winter Weather Patterns
Forecasters predict an unusually potent El Niño event, potentially bringing milder conditions to New York City while posing flood risks to other regions.
An exceptionally strong Super El Niño, described as "off the charts" by forecasters, is poised to significantly influence weather patterns across the United States this winter. The World Meteorological Organization (WMO) anticipates the event, measured by sea surface temperatures, could reach more than six times the intensity of a typical El Niño between November and January.
"This is literally off the monitoring charts that we have used for the past four decades," said Celeste Saulo, secretary of the WMO. This "behemoth" weather system is expected to bring a milder winter to the Northeast, with New York City potentially experiencing autumn-like conditions into January.
According to AccuWeather Senior Meteorologist Matt Benz, New York City could see considerably less snowfall than last year. While the city recorded 43 inches of snow in the previous winter, forecasts suggest only 10 to 20 inches for the upcoming season. "Fall will linger longer this year," Benz stated. "We expect winter to arrive later." He added that the Tri-State area might not experience typical winter weather until mid- to late January.
While the Northeast may experience a milder winter, other parts of the country face different conditions. Northern California could be hit by frequent storms bringing rain and wind, with a heightened risk of coastal erosion. California and the desert Southwest are identified as areas with the highest risk of flooding. Additionally, parts of the Southern US, including the Northern Gulf Coast, are expected to experience more intense rainfall events.
The western mountainous regions, such as the Rockies and the Sierra Nevadas, along with portions of the Midwestern plains, are likely to receive heavier snowfall. Benz cautioned that while El Niño is a recurring phenomenon, the current event could be among the strongest on record.
Globally, the UN's emergency relief chief, Tom Fletcher, characterized the Super El Niño as a potential "wrecking ball," citing risks of extreme heat, droughts, and floods worldwide.
