The U.S. has a 74% chance of La Niña conditions, while there is a 40% chance of this being a moderate event. Will Texas freeze again in 2024? Here's what the Farmers' Almanac winter forecast predicts
La Niña is considered to be the cool phase of the El Niño-Southern Oscillation (ENSO) and is characterized by lower-than-average sea-surface temperatures, with anomalies of at least -0.5 degrees ...
The National Oceanic and Atmospheric Administration’s Climate Prediction Center says there is a 60% chance that a weak La Nina event will develop this autumn and could last until March. La Nina is part of a natural climate cycle that can cause extreme weather across the planet — and its effects vary from place to place.
For example, the La Niña winters of 2022-2023 and 2023-2024 both experienced above normal temperatures yet they still came with a "substantial" cold snap, added Husted.
La Niña is marked by sea-surface water temperatures in a key area of the eastern Pacific. (Image: NOAA/CPC) La Niña typically has the greatest impact on the Northern Hemisphere in the winter ...
An especially strong Walker circulation causes La Niña, which is considered to be the cold oceanic and positive atmospheric phase of the broader El Niño–Southern Oscillation (ENSO) weather phenomenon, as well as the opposite of El Niño weather pattern, [19] where sea surface temperature across the eastern equatorial part of the central ...
The strength of La Niña matters — the stronger it is the more of a “consistent” impact it can have on weather, according to Emily Becker, an atmospheric scientist at the University of Miami.
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 ...
