For the past week, Rwanda continues to experience rainfall in a period of the year previously known to be a dry season that normally starts in the month of June through July and August. September is normally when rains start.
Although the RMS had communicated on 17th that after four days that normal dry weather would return, this has not been the case instead there have been more experiences of rains.
According to Rwanda Meteorological Services (RMS), the rains we are experiencing are caused by two masses of air (winds). One that has travelled from the Indian Ocean, and over Lake Victoria and is therefore warm and wet.
Warm air always rises so when the two air masses converge, the warm air is forced upwards by the cooler air. As it rises into the atmosphere, the moisture cools and forms a cloud. The cloud condenses and thus causes rainfall.
The RMS body also notes that during the months of June, July and August, the winds over Rwanda come from the south East.
The communiqué also explains that because the winds travel overland, they lose their moisture along the way. This thus causes hot and dry weather in Rwanda commonly referred to as ‘Dry Season’.
RMS is Rwanda’s national weather service under the patronage of Ministry of Infrastructure. RMS observes weather from across the country on a daily basis by gathering data from scattered weather centers
