The United Nation has warned that the El Nino weather phenomenon will intensify during the latter part of 2026.

El Nino will quickly develop into a strong event between July and September, fuelling the likelihood of extreme weather, the United Nations' weather and climate agency warned Friday.

The World Meteorological Organization said El Nino had already set in, and would quickly gain strength, as it warned countries to brace for impact.

El Nino is a natural climate phenomenon that warms surface temperatures in the central and eastern equatorial Pacific Ocean, bringing worldwide changes in winds, pressure and rainfall patterns.

It typically takes place every two to seven years and lasts around nine to 12 months. It is known to bring drought conditions to South Africa, and economists are already warning that it could lead to a surge in food prices.
