The torrential rains came right after a prolonged drought in vast swaths of the country that has left many areas dry and crops in fields scorched. The eastern region of Uganda is prone to flooding after heavy rains, but the whole country is vulnerable to natural disasters Intense rainfall has led to many deaths in the past. More than 30 people were killed and many more were displaced when floods swept away homes in the country's eastern Bududa district in 2018. In 2010, around 80 people were killed in Bududa, one of Uganda's worst disasters in recent years because of a torrential downpour. More than 300,000 people have been affected by floods and landslides in the Bududa and Sironko districts - both in eastern Uganda and Bundibugyo in the western region, according to a report by the United Nations Office for the Coordination of Humanitarian Affairs. An estimated 65,000 people have been displaced, according to the report.
