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.

A weak La Nina event has arrived in the Pacific, bringing colder waters and potentially cooler weather. Despite being delayed and relatively weak, La Nina may bring intense storms and rainfall ...

This La Niña event is expected to be weak and its time of emergence may not have the impact it would otherwise have had, according to meteorologists ...

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 ...

La Niña is part of a natural climate dynamic, along with the better-known El Niño, called El Niño–Southern Oscillation (ENSO). La Niña is ENSO’s cool phase, while El Niño is its warm phase.

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 ...

who is also one of the main authors of NOAA’s La Niña/El Niño blog, explained. The phenomenon is marked by cooler than average water temperatures in the equatorial Pacific, along with ...

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 ...

During La Nina, strong trade winds push warm surface water westward, allowing colder water from the deep ocean to rise up along the South American coast ...

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 ...

La Niña is usually associated with drier conditions across the southern part of the U.S. and wetter conditions to the north. This reflects how La Niña is associated with a more poleward-shifted jet ...

La Niña is considered 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 Celsius (-0 ...
