WMO Forecasts Extraordinary El Niño Strength

The projection raises the risk of large shifts in rainfall and temperature across Argentine provinces, prompting stepped-up forecasting and local preparedness.

Overview

The World Meteorological Organization says El Niño is expected to reach an extraordinary intensity and that its effects could continue into early 2027.
Argentine outlets and climate specialists report the event is already active in the country and expect changes to local rainfall and temperature patterns in the coming weeks.
Forecasters and experts say impacts will vary by region, with the Litoral and Pampas likely to see heavier rains and the northwest and northeast particularly exposed to stormy conditions.
Practical household steps advised by local coverage include cleaning gutters and drains, checking roofs and seals, pruning overhanging branches, securing outdoor items, and testing emergency lighting and electrical safety.
Specialists warn an extreme 'Súper Niño' remains a developing possibility and urge continuous monitoring of forecasts and strengthened provincial and municipal preparedness measures.
