NOAA has declared that a La Niña is underway. This cool weather event is likely to be shorter and weaker than usual, but will still affect global weather and climate.

The long-awaited La Niña has finally arrived but it is weak and meteorologists say it's unlikely to cause as many weather problems as usual. Experts have been expecting the arrival of the climate phenomenon since last spring but finally,

Weather patterns across the U.S. and the world from October through December resembled patterns from previous La Niña events. 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,

It's not great news for the Gulf Coast and other storm-prone regions: La Niña is associated with more tropical activity in the Atlantic Ocean. But this event might not make it to hurricane season.

A long-awaited La Niña has finally appeared, but meteorologists say the periodic cooling of Pacific Ocean waters is weak and unlikely to cause as many weather problems as usual.

NOAA predicts La Niña to persist until spring 2025 Event likely to be weaker and shorter than typical La Niñas Global weather patterns, including hurricanes, could still be affected

If you live in a city where a meteorologist mentions an "La Niña" or "El Niño" it is important to distinguish the difference between the two.

The National Oceanic and Atmosphere Administration announced this week La Niña has arrived. This usually means the northern parts of California and the U.S. see more rainfall while Southern California sees less rain.
