US, IMD Differ on La Niña Status; IMD Expects Indian Monsoon Impact
The US weather body says La Niña is here, but India and other countries disagree.
They all think it might end soon.
India expects La Niña to affect its monsoon.
US' NOAA's CPC says La Niña has emerged and will continue through winter.
IMD and other global agencies disagree, predicting La Niña to emerge later or not at all.
All agencies agree La Niña, if it occurs, will be short-lived, ending by March 2026.
La Niña may ease early 2026, with a shift towards ENSO-neutral likely between January and March.
IMD expects La Niña and negative IOD to influence rainfall over Tamil Nadu and southern India.
