🆕 WMO confirms: El Niño conditions are developing and are set to influence global temperature and rainfall patterns around the world in the months ahead. Most forecast models suggest it will be at least moderate – possibly strong.
Be prepared. More info➡️ https://t.co/htyps0XfsE

An El Niño is emerging. What do you know about it?

El Niño is a powerful natural climate pattern that warms ocean waters in the central and eastern Equatorial Pacific. It typically occurs every 2-7 years, but no two El Niños are exactly alike.

[António Guterres @antonioguterres]

El Niño is arriving on our doorstep in the coming months with 90% certainty.

The world must treat it as the urgent climate warning it is.

The only effective response is #ClimateAction equal to the crisis – ending the addiction to fossil fuels, accelerating the shift to renewables, protecting the most vulnerable, and delivering early warning systems for all.

In 2025, temperatures in Latin America & the Caribbean were +0.4 °C hotter than average. But temperature does not rise equally everywhere nor across time.

Changing temperatures have cascading impacts on health, agriculture, energy demand & ecosystems. https://t.co/mF1aOExbfA

There is a 55% chance of a below-normal season for the Atlantic basin this year, according to @NOAA.

Forecasters predict a 8-14 named storms, 3-6 to become hurricanes. Tropical hurricanes are named by WMO in the interests of public safety.

⚠️Extreme rainfall and droughts are intensifying with climate change

🌳Less water, fewer trees and rising temperatures are a challenge in urban areas

💰Every $1 invested in early warning systems yields $9 in benefits

🗣️WMO Deputy Secretary-General Ko Barrett:

❝A couple of important water-related actions that could potentially come out of the COP would be to recognize fully the connection between water and climate in the conference itself❞

[World Meteorological Organization @WMO]

A below-normal hurricane season for the Atlantic basin is forecasted this year, according to @NOAA.
The outlook is influenced by expected competing factors such as El Niño, warmer ocean temperatures and weaker trade winds.
