The Director General of the Kenya Meteorological Department (KMD), Edward Muriuki, has linked Kenya’s unusual February rains to the Madden-Julian Oscillation, a tropical weather phenomenon that moves eastward and influences rainfall patterns in tropical regions.
Muriuki explained that the recent off-season rainfall was caused by the oscillation’s rainfall-enhancing phase, which increased precipitation over the past two weeks.
Kenya is now transitioning into the long rains season, which typically lasts from March to May, and these off-season rains mark its early onset.
The Intertropical Convergence Zone (ITCZ) also plays a major role in rainfall patterns, shifting north and south with the sun and determining the timing and intensity of seasonal rains.
Muriuki warned of heavy rainfall expected in 22 counties, including Kisumu, Siaya, Busia, Migori, Nairobi, Nakuru, and Meru, which could cause flooding in low-lying areas.
Residents in flood-prone regions were urged to take necessary precautions, while local authorities were advised to remain alert and ready to respond.
The KMD emphasized the importance of accurate weather monitoring and forecasts, noting that ongoing research on the Madden-Julian Oscillation and improved forecasting systems will help communities adapt.
The department continues to provide updates to ensure the public is informed and prepared as Kenya enters the peak of its long rains season.
