Kenya El Niño warning: Why prolonged rain could drive bigger impacts

Kenya's meteorologists have issued a warning about the potential impacts of El Niño-enhanced rains, emphasizing that the duration and persistence of rainfall, not just the intensity of individual storms, could determine the severity of flooding and other hazards. Richard Muita, Director of Regional Meteorological Services-Eastern, explained that the interaction between El Niño and the Indian Ocean Dipole (IOD) could lead to above-normal rainfall across much of the country.

The IOD, a separate climate phenomenon, is expected to be strong and could coincide with the El Niño signal during the upcoming rainy season. When these two forces combine, their effects could be amplified, potentially leading to significant impacts. Muita cautioned that the forecast should not be viewed as a guarantee that every part of Kenya will experience the same conditions, as the Greater Horn of Africa is expected to see considerable variation in rainfall probabilities and amounts.

Areas already vulnerable to flooding, such as low-lying regions in eastern Kenya and areas inhabited by pastoralist communities, are likely to face more intense direct impacts. Muita urged communities in exposed areas to remain vigilant and cooperate with government agencies and humanitarian organizations, including the Kenya Red Cross, to take appropriate action and protect lives and property.
