What the Pacific ‘Blob’ + La Niña Means for Winter in the US
NOAA forecasts a weak La Nina likely to continue through early 2026 with a 75% chance, potentially influencing late hurricane season activity and winter weather patterns.
- On Oct. 9, the Climate Prediction Center declared La Niña has officially arrived, confirmed by the National Oceanic and Atmospheric Administration.
- A La Niña forms when central Pacific Ocean cools by half a degree Celsius , influencing weather in Indonesia, the Philippines, parts of Australia, the Middle East, and eastern China.
- Traditionally, La Niña reduces Atlantic wind shear, allowing more storms especially late and in the Caribbean; an average season sees 14 storms and seven hurricanes, though as of Oct. 8 there have been 10 named storms and four hurricanes.
- Model forecasts show NOAA and Columbia University indicate this La Niña is likely weak and may disappear, with Michelle L'Heureux saying `There is a three out of four chance it will remain a weak event`.
- With the season ending Nov. 30, forecasters note this La Niña could affect the 2025 hurricane season tail and a 1999 economic study found droughts cost U.S. agriculture $2.2 billion to $6.5 billion.

AlKhaleej TodayLa Nina returns but expected to remain weak, says US weather agency
WASHINGTON, Oct 10 — The climate phenomenon known as La Niña has returned, a US agency announced yesterday. It is expected to remain weak, limiting its ability to cool the planet and supercharge Atlantic hurricane activity.La Niña is a naturally occurring climate pattern that cools surface temperatures in the central and eastern equatorial Pacific Ocean. Because of changes in vertical wind shear — the variation in wind speed and direction high …
A foreboding weather pattern has emerged: Here’s what it means for winter
La Niña, a climate pattern that can affect weather worldwide, has officially arrived. La Niña is fueled by colder-than-normal Pacific Ocean temperatures, which then affect the pattern of the Pacific jet stream. It’s the cooler counter to El Niño, which involves warmer-than-normal ocean waters. Both are part of a weather system called the El Niño-Southern Oscillation (ENSO). La Niña conditions emerged in September, the National Weather Service’s …
