Meteorologists say a weak La Nina weather event has arrived but will bring fewer storms than usual. Here's how the Pacific El Nino and La Nina weather phases can influence extreme weather globally.

An El Niño weather pattern—La Niña’s counterpart—brought the warmest winter on record last year. La Niña conditions emerged in December and will likely persist through April, though the ...

Forecasters closely monitor La Niña and its counterpart El Niño because they influence global weather in a way that’s largely consistent and predictable well in advance – especially when the ...

The last El Niño, the periodic warming of Pacific Ocean waters, finished in June 2024. NOAA forecasters have been expecting La Niña for months. The previous La Niña concluded in 2023 after an ...

However, it is expected to be weaker and shorter than usual. La Niña is the cold phase of a natural climate pattern called the El Niño Southern Oscillation (ENSO) cycle, which is a pattern of ...

But that won’t totally eliminate its effect. And, despite its late arrival, it’s already played a clear role in this winter’s weather. Forecasters closely monitor La Niña and its counterpart El Niño ...

As the climate continues to change, there are challenges in monitoring and predicting El Niño and La Niña events. The best source of information is the Bureau’s outlooks as they encapsulate ...

La Nina, the flip side of the better-known El Nino, is an irregular rising of unusually cold water in a key part of the central equatorial Pacific that changes weather patterns worldwide.

Last winter (2023-2024) was an El Niño winter marked by cooler and wetter weather for the southern states. The last La Nina ended in 2023 after an unusual three-year stretch. The odds favor ENSO ...
