The United Nations' World Meteorological Organization (WMO) has warned that the warming El Nino weather phenomenon could return later this year as the cooling La Nina fades.

• There is a 40% chance of El Nino developing between May and July.
• The WMO community is closely monitoring conditions to inform decision-making.
• Naturally occurring events like El Nino and La Nina are occurring against the backdrop of human-induced climate change, which exacerbates extreme weather.
