"Daytime (maximum) temperatures above 30°C are expected in several parts of the country, including the Coast, the South-eastern Lowlands, North-eastern, and North-western Kenya," the department noted.
At the same time, some high-altitude areas were to experience cold nights, with temperatures expected to drop below 10 degrees Celsius.
