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.

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 ...
The weak La Niña is forecast to stick around through April before yielding once again to so-called neutral — not La Niña or El Niño — conditions, according to the Climate Prediction Center.
The term La Niña may be one that casual weather observers, as well as aficionados, hear meteorologists using from time to time, especially when breaking down long-term weather trends or providing ...
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 ...
A weak La Niña is less likely to have a significant impact on weather patterns during the winter and spring. ... La Nina climate pattern officially arrives and is expected to persist through winter.
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 the eastern Pacific. These cold ocean temperatures and changes in the atmosphere affect the position of the jet stream — a narrow band of fast moving air flowing from west to east around the ...
La Niña, which means "little girl" in Spanish, is a climate phenomenon characterized by the cooling of sea surface temperatures in the central and eastern equatorial Pacific Ocean. La Niña and ...
