A detailed analysis found La Niña began in December 2024 with a weak La Niña favored during the rest of this winter. La Niña is the cool phase of ENSO (El Niño-Southern Oscillation) that is ...
Across Alaska, El Niño events do not have a correlation towards dry or wet conditions; however, La Niña events lead to drier than normal conditions.During El Niño events, increased precipitation is expected in Southern California, Arizona, and New Mexico due to a more southerly, zonal, storm track over the Southwest, leading to increased winter snowpack, but a more subdued summer monsoon ...
During La Niña, increased precipitation is diverted into the Pacific Northwest due to a more northerly storm track. [209] During La Niña events, the storm track shifts far enough northward to bring wetter than normal winter conditions (in the form of increased snowfall) to the Midwestern states, as well as hot and dry summers.

El Niño has been shaping the weather across North America all winter, but the tides are changing, and a major shift is on the horizon. On Thursday, NOAA issued a La Niña watch, explaining that ...
Similar concerns exist for much of the Southwest during a La Niña winter. "As the active storm track remains displaced well to the north, the Southwest typically stays warm and dry," Bauer explained.
The 2020–2023 La Niña event was a rare three-year, triple-dip La Niña. [1] The impact of the event led to numerous natural disasters that were either sparked or fueled by La Niña. La Niña refers to the reduction in the temperature of the ocean surface across the central and eastern equatorial Pacific, accompanied by notable changes in the ...
El Nino is the warm phase and happens when trade winds that typically blow across the Pacific toward Asia weaken, allowing warm ocean waters to pile up along the western edge of South America. But during La Nina, the trade winds intensify and cold water from the depths of the sea rises up, resulting in cooler than average ocean temperatures in ...
However, for the following three-month period running from March-May 2025, there's a 60% chance for La Niña to fade with the climate pattern returning to neutral status – neither La Niña or El ...
