“Nairobi area received light to heavy rainfalls compared to the rest parts of the country with received heavy rainfall.” Koros said.

Warning of heavy rains
“We use the feedback shared with us to understand the weather outlook in different parts of the country,” Koros said, “especially in areas where we do not have our stations installed. For instance, reports from the media also help inform our assessments.”

Mr Koros noted that reports continue to indicate intense rainfall in several regions.
“Today, I am receiving reports that some parts of the country are experiencing heavy rainfall. People should still expect heavy rainfall,” he emphasized.
Flood waters may accumulate rapidly including in areas where heavy rain has not directly fallen.
“Flood waters may appear in places where it has not rained heavily,” KMD said, “especially downstream.”
