The month of April marks the peak of the March to May ("Long Rains") seasonal rainfall while March is normally associated with the onset of rainfall over most parts of the country. The rainfall outlook for April 2018 indicates that most parts of the country are likely to experience enhanced rainfall especially in western and mountainous areas of Elgon. Overall, wet conditions and reduced temperatures are likely to prevail during the month of April 2018 over most parts of the country.
Overall, the April forecast indicates that most parts of the country are expected to have enhanced rainfall. However, the mountain areas of Rwenzori and Elgon plus the highlands of South Western Uganda are expected to receive above the average rainfall which might impact negatively to the communities in those areas.
The cold and hazy conditions being experienced over most parts of the country have been caused by the winds blowing from the Northern Hemisphere which is experiencing winter towards our region and hence bringing the cold conditions.
Cold and hazy conditions are expected to prevail over most parts of the country until mid-January 2018 when the phenomenon will reduce.
