Uganda is experiencing some of its most unpredictable weather in 20 years. Weather experts say the reason is El Nino: a climate event that affects weather conditions worldwide. El Nino takes place when water temperatures in the Pacific Ocean warm, and redirect wind movements.

Godfrey Mujuni works at Uganda's meteorological data center. He says rains will continue through what should be the country’s dry season. He says that if El Nino remains strong, he expects heavy rainfall during the months of January and February.

Heavy rains have already led to a rise in cholera cases. The disease has killed at least six people in western Uganda. In rural, mountainous areas, people have been asked to leave their homes because of the risk of landslides.

In the capital, Kampala, a number of wetland systems are responsible for drainage. These systems remove surplus water during periods of increased rainfall. However, both legal and illegal building projects have blocked the flow of water.
