The March to May 2011 seasonal rainfall has almost ceased over most parts of the country. As per the prediction, the rainfall was highly depressed and poorly distributed, both in time and space, over most parts of the country. This was more so over the North-eastern parts of Kenya and the Coastal strip where most meteorological stations recorded less than 50 percent of their seasonal Long-Term Means (LTMs) for March to May. The rainfall was also characterised by late onset in some parts of the country. The poor rainfall performance impacted negatively on the agricultural and pastoral activities in various parts of the country. The water levels in the hydroelectric power generation dams also went down following the generally poor rainfall performance in the catchment areas.
The climate outlook for June-July-August (JJA) 2011 season indicates that the Western highlands are likely to receive near normal rainfall with a tendency to above normal while generally depressed rainfall is likely to be experienced over the Central Rift Valley and the coastal Strip. The central highlands including Nairobi area are expected to experience cool, cloudy and drizzly conditions. Rainfall emanating from western Kenya may occasionally spread to the Central districts and Nairobi. Fairly low temperatures are also expected to be experienced in Central Rift Valley and parts of the highlands west of the Rift Valley).>>More
