Autumn and winter in New York and at least other 15 East Coast states see mild temperatures, but this can change “surprisingly”, due to the La Niña phenomenon, which could cause more intense rains and snowfalls.
A similar situation occurred in the winter of 2021-2022 when the Empire State and various entities , including the New England region, had days of almost summer weather during the season, but the temperature dropped several degrees from one day to the next.
The projections of experts from the National Meteorological Service and AccuWeather -one of the most reliable systems- coincide in the conditions that La Niña will cause, which is a phenomenon that causes colder water in the equatorial Pacific , which amplifies the “polar jet” current, generating more intense winter storms, even if they seem isolated.
Meteorologists attribute the current weather pattern to La Niña, as possible warmer temperatures along the East Coast.
“Warmer-than-average temperatures are favored in the southeastern US and along the Atlantic coast,” says an AccuWeather report.
However, the pattern is not consistent, so people will see sudden changes in temperature and generate “massive storms”.
Although the first waves of cold air are affecting New York and several states, before the official start of winter AccuWeather meteorologists note that this will change as winter progresses, but the weather will be almost unpredictable.
“Residents of the Northeast and Midwest will experience some early winter in November and December as waves of cold air descend from Canada, but the largest gusts of cold air will remain until later in the winter,” AccuWeather said.
A study by 2018 published in Nature Communications had warned of these sudden changes and the severe storms caused by La Niña.
“This allows the masses of Arctic air to expand further south while increasing the probability of heavy snowfall”, it was indicated then.
