The forecast shows that there will be isolated storms and possible flooding over some parts of the Highlands West of the Rift Valley and Northwestern.

North-western Kenya (Turkana and Samburu Counties) will experience morning rains, afternoon showers, and thunderstorms as well as night showers are likely to occur over a few places, occasionally spreading to several places, during the first half of the forecast period.
