World Meteorological Organization: El Niño weakens but impacts continue. From March to May, temperatures will be above normal in almost all land areas.
El Niño causes flooding in the Horn of Africa and the southern United States. It also causes unusually dry weather in Southeast Asia, Australia and southern Africa, and intensifies drought in northern South America. The El Niño phenomenon occurs on average every 2 to 7 years, usually lasting 9 to 12 months, and affects weather changes in many parts of the world.
